1 Description and Specifications

1.1 General Description

The RTS Model 803 Master Intercom Station is an updated replacement to the popular Model 802. By employing many of the technological breakthroughs that have occurred since the design of the 802, RTS has been able to integrate into the 803 the complete circuitry for all 802 base features and options except squawk. For example, call signaling is now standard on all twelve intercom channels. For applications requiring 4-wire operation, IFB panel emulation or ISO panel emulation the circuitry is already there; you simply install an option cable to the back panel, set one or two internal DIP switches (IFB and ISO emulate only) and you're ready to go. For all other applications, everything you need is "in the box".

In terms of form, fit and function the 803 can directly replace the 802 with the following exceptions: 1) squawk is not supported on the 803; 2) many users do not require a front panel gooseneck microphone, so that is now supplied as a separate plug-in style microphone (unlike the 802 microphone which was permanently mounted); 3) the 803 includes built-in DC blocking for the intercom channels, so when connecting to powered intercom channels that were previously connected to an 802, the external isolation capacitors are no longer required and may have to be removed for best audio performance; 4) although seldom done in practice, the 802 could be DC powered; the 803 cannot.

In addition to it's role as a product replacement for the 802, the 803 also adds several new features in response to the increasing communication needs of a variety of users. Following is a general description of 803 features. Expanded descriptions of these features, a detailed comparison and contrast with the 802, and a list of specifications may be found on the following pages.

1.1.1 General 803 Features

Setup Mode Features for Talk Buttons: Setup mode features that are accessed using the talk buttons are printed at the very top of the front panel. For example, access BUTTON LOCK by pressing the TALK 1 button during setup mode.

Setup Mode Features for Listen Buttons: Setup mode features that are accessed using the listen buttons are printed just below the setup mode features for the talk buttons. For example, access RELAY 1 by pressing the LISTEN 1 button during setup mode.

Setup Mode Features for Keypad Buttons: Some names for setup features are printed in italics next to the buttons. Some are printed in italics on the buttons. For example, access the LOCAL IFB feature by pressing button 2 during setup mode. Access presets by tapping any one of the buttons labeled PRE 1 through PRE 6. Labels that are not italicized are operating features and not setup mode features.

Note: some italicized labels are not setup mode features, but are submenu items for use with a particular setup mode feature.

1.1.3.2 Setup Mode Features

♦ 801 emulation: Default: 801 emulation disabled. ♦ Internal/external ISO select: internal is used when the

803 emulates a VCP panel; external is used when the 803 connects to an external VCP panel, or when ISO is not used. Default: external.

♦ ISO listen disable: turn off all activeconference chan-

nel listen buttons during ISO: Default: off (listens not disabled during ISO).

♦ ISO enable/disable: Default: disabled. ♦ IFB talk disable: turns off all active conference chan-

nel talk buttons during IFB. Default: off.

Jumpers

Separate jumpers set the "off" brightness for the keypad buttons and for the talk/listen buttons. Available settings are high, low and off.

2W/4W Setup

Each intercom channel may be set for two-wire operation, four-wire operation, or both (not applicable to auxiliary channels). For two-wire operation, nulling may also be optionally turned on or off. Thus, theintercomchannels may be individually programmed to operate with a variety of inputs and outputs. For example,two-wire operation won't work with a typical two-way radio, which often requiresa four-wire, unbalanced connection. R TS "TW" belt packs and intercom channels, of course, operatein two-wiremode, and nulling is normally activa tedwhen connecting to TW devices.

Default setting: all channels set for two-wire operation with nulling.

AUTO LISTEN Setup

Each listen button may be individually programmed for auto listen. When auto listen is assigned to a channel, that channel's listen button will automatically turn on when there is an incoming call signal from another intercom station.

Default setting: auto listen is disabled for all channels.

AUTO TALK Setup

Each talk button can be individually programmed to automatically activate when an incoming call signal is received on its intercom channel. The microphone also activates, so that the803 user can talk to the caller without having to press any buttons.

Default setting: auto talk disabled for all channels.

Default setting: caller ID is disabled on all intercom channels.

CHIME SELECT Setup

Chime select lets you select one of 3 chime tones for incoming call announcement on the intercom channels. The currently selected tone always sounds at power-up or after a reset.

BILAT SELECTSetup

If one or more of the auxiliary channels 13-15 are not being used with the ISO and IFB options, these channels may be assigned to front-panel buttons (usually unused keypad buttons) for talk and listen activation.

Default setting: channels 13 through 15 unassigned.

BUFFER RECALL Setup

The 803 has an internal buffer which stores the current status (on or off) for all 24 talk and listen buttons. The contents of this buffer can be recalled and stored in any one of the 6 presets (the PRE 1 through PRE 6 buttons on the keypad). You can then activate that preset button at any time during normal operation to recall the saved talk and listen button settings.

Default setting: N/A

BUTTON LOCK Setup

This feature locks selected talk and listen buttons in the on or off position. You must also use this feature to unlock buttons.

Default setting: all buttons unlocked.

CALL DISABLE Setup

Default setting: a single high-low tone

EXT CONTACT Setup

This feature lets you activate any one button on the front panel (except CALL & SETUP) using an external switch. You can also activate a group of buttons by assigning those buttons to a preset and then activating the preset with the external switch.

Default setting: the external switch activates the MIC ON button on the keypad.

INSTANT MIC Setup

In order to talk to an intercom channel, both the MIC ON button and the talk button for that channel must be on. In some cases it may be convenient to have both of these activate when the talk button is pressed. This is referred to as "instant mic".

Default setting: instant mic is disabled for all channels.

LATCH DISABLE Setup

Most front panel buttons can operate in both momentary and latching mode. You may not want certain buttonsto have the ability to latch (for example, a button that talks to a radio transmitter). You can disable latching for these buttons.

This feature disables or enables call signal reception on selected intercom channels. When call signal reception is disabled on a channel, there will be no chime tone or button flash to indicate an incoming call. Outgoing call signals are not affected.

Default setting: call reception enabled for all intercom channels.

CALLER ID Setup

Caller ID causes the listen button for an intercom channel to flicker when audio is being received on that channel. This provides a visual cue of which channel is talking. You can set caller ID to provide this indication when the listen button is on and/or off.

Default setting: latching operation enabled for all buttons that support latching.

LOCAL IFB Setup

Any of the intercom channels 1-12 can beconverted into a local IFB channel. (Not applicable to channels 13-15). A local IFB channel normally sends a program feed to a remote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the program feed and then talk to the remote listener. The program source for a local IFB channel can be either of the program 1 or 2 inputs, or the listen input for that channel.

Default setting: local IFB is off for all channels.

MIC SELECT Setup

This feature selects which microphone inputs areactivated by the PANEL ON button in both the on and off positions.

Default setting: the PANEL ON button selects the front panel gooseneck microphone in the on position and the front panel headset microphone (either carbon or dynamic) in the off position.

PRESET EXCLUDE Setup

Selected talk and listen buttons may be excluded so that they cannot be assigned for activation using the preset buttons.

Default setting: talk turns off listen is deactivated for all channels.

TALK TURNS ON LISTEN Setup

You can set the talk button for any channel so that activating that talk button will automatically turn on the listen button.

Default setting: talk turns on listen is deactivated for all channels.

TOTAL MUTE Setup

Total mute lets you turn off all talk and listen buttons by tapping a single button.

Default setting: no talk or listen buttons are excluded from assignment to presets.

PRESETS Setup

Any combination of talk and listen buttons may be assigned for activation by any one of the 6 preset buttons.

Default setting: no presets setup.

RELAY Setup

Any of the 6 built-in relays may be assigned for activation by selected front panel buttons.

Default setting: no relays assigned.

SP/L/R (Speaker Left/Right Select) Setup

Each audio input can be directed to the speaker, the left headphone, the right headphone, or any combination of the three.

Default setting: all audio inputs are assigned to the speaker and to both the right and left headphones.

SPECIAL PURPOSE Setup

This feature is only available for special-order products.

TALK TURNS OFF LISTEN Setup

Occasionally, activating a talk button while the listen button is on may cause feedback, echo or other undesirable sounds. This may only happen on selected channels, or it may happen on all channels in certain environments or with certain audio sources. You can eliminate this problem by setting selected listen buttons to automatically turn off while their associated talk buttons are on.

Default setting: no total mute button assigned.

VOXENABLESetup

The 803 can be set for voice-activated microphone. When this feature is enabled the microphone will remain off when you are not speaking into it. When you do speak, the microphone will turn on, and your voice will be transmitted on any channels that have talk buttons activated.

Default setting: vox disabled.

1.1.4 803 Compatibility with RTS Video ISO System

The 803 can be connected to an external VCP-6 or VCP12 Video ISOPanel. For external ISO, button activation at the VCP panel causes deactivation of all conferencechannel talk buttons at the 803 (listen button deactivation may also be setup via an internal 803 DIP switch), and the 803 mic audio is automatically routed to the VCP system.

The 803 can also emulate a VCP-6 or VCP-12 ISO Panel. VCP-6 emulation requires installation of an optional 50pin cable and resetting internal DIP switches. VCP-6 emulation takes over 3 intercom channels (and their talk and listen buttons) and auxiliary channel 15. VCP-6 emulation can be installed along with Model 4001 IFB panel emulation. VCP-12 emulation is similar to VCP-6 emulation, but requires installation of two 50-pin option cables. VCP12 emulation takes over 6 intercom channels and auxiliary channel 15. Also, IFB panel emulation is not possible when VCP-12 panel emulation is installed. (However, local IFB is still possible on any unused intercom channels.)

1.1.5 803 Compatibility with RTS Model 4000 IFB System and Local IFB

1.1.6 Comparison of 803 and 802

1.1.6.1 Retained Features

The 803 can be connected to an external 4001 or 4002 IFB Panel. For external IFB, button activation at the IFB panel causes deactivation of all conference channel talk buttons at the 803, and the 803 mic audio is automatically routed to the IFB system.

The 803 can also emulate a 4001 or 4002 IFB Panel. Model 4001 IFB Panel emulation requires installation of an optional 50-pin cable and resetting internal DIP switches. Model 4001 emulation takes over 3 intercom channels (and their talk and listen buttons) and auxiliary channel 13. Model 4001 emulation can be installed along with VCP-6 ISO Panelemulation. Model 4002 IFBPanel emulation is similar to Model 4001 emulation, but requires installation of two 50-pin option cables. Model 4002 emulation takes over 6 intercom channels and auxiliary channels 13 and 14. Also, VCP emulation isnot possible when Model 4002 emulation is installed. However, external ISO is still possible.

Any intercom channel that is not being used for intercommunication or IFB/ISO panel emulation may be configured as a local IFB channel. This channel can be set to normally monitor a program input at either the program 1 or 2 input. Or, if the local IFB channel is operated in 4wire mode, the listen input may be used as the program source. Pressing the talk button for that channel disconnects the program input and causes the 803 operator's voice to be heard at the IFB output.

2.2 Option Cable Installation

2.2.3 4-Wire Option Cable Notes

2.2.1 General Information

The connector openings for the option cables are labeled on the back panel as follows:

ISO 1 Connector: Used for VCP-6 and VCP-12 ISO Panel Emulation; provides connections for ISO1 through ISO6.

IFB 1 Connector: Used for 4001 and 4002 IFB Panel Emulation; provides connections for IFB1 through IFB4 and SA1 (Stage Announce 1)

IFB 2 / ISO 2 Connector: Can be used with the ISO1 connector for VCP-12 Panel Emulation (provides the ISO7 through ISO12 connections). Or, can be used with the IFB1 connector for 4002 IFB Panel Emulation (provides the IFB5 through IFB8 and SA2 connections)

2.2.2 Back Panel Connector Installation

1. Remove the 12 top cover screws and remove the cover.

2. Select thedesired connector opening in the back panel. Remove the 3/16 jack screw and the phillips screw that hold the mesh screen and white plastic cable retaining clip in place.

3. Insert the 50-Pin"D" connector of the option cable into the connector opening. The connector should be oriented the same way as the TWO WIRE LINE CONNECTOR that is already installed.

4. Reinstallthe white plastic cable retaining clip and the screws. Note that the "D" connector has threaded inserts, so the hex nuts that were originally used are no longer required.

5. Refer tothe following installation notes for each option cable to complete the installation.

Connect the 4-wire cable to J55 on the main circuit board. The red wire on the cable corresponds to pin 1 of J55. Note: there are no internal DIP switches directly related to the 4-wire option. You configureindividual channels to operate in 4-wire mode via the front panel setup mode. See "2W/4W Setup", page 43 for details.

2.2.4 IFB and ISO Option Cable Notes

2.2.4.1 General Notes

The priority and tally connectors are identified in Figure

2. Only one priority connector is used for each cable. It determines who gets controlling access to IFB's and ISO's when there is more than one IFB or ISO panel in the intercom system. Priority 1 overrides all panels set to priority 2, 3, or 4; priority 2 overrides priority 3 and 4 etc. When an IFB or ISO button is pressed at a panel which has a higher priority, any lower priority panels will be disconnected from that IFB or ISO until the buttonis released on the higher priority panel. If the same IFB or ISO button is activated on two panels with the same priority, both will be able to talk to the IFB or ISO at the same time.

The tally connector is used in all cases. It distributes button-pressed signals throughout the intercom system to notify all other IFB or ISO panels when any IFB or ISO button has been pressed.

Important! The priority and tally connectors can be installed backward if the correct location of pin 1 is not observed. Also, the connectors can be misaligned so that all pins are not connected. Check carefully when installing.

2.2.5 ISO 1 Cable Notes

♦ Connect the desired priority connector to J329 on the

main circuit board. Connectthe tally connector to J330.

♦ Set DIP switches S2-4 and S2-6 (page 16 ) to the ON

position to activate and use this connector*. DIP switch S2-5 may optionally be set to the ON position if you want all conferencechannel listen buttons to automatically shut off whenever any ISO button is activated (all conference channel talk buttons always shut off during ISO).

♦ When installing button inserts for ISO 1 (page 17)

note that different buttons are reserved,depending on whether or not another IFB or ISO connector is installed.

♦ Use a 50-pin cable to connect from the ISO 1 connec-

tor to a Model VIE-306 Video ISO Electronics Unit. Typical connections are shown in Figure 20, page 40. Refer to your Model VIE-306 Manual for further information. If you are only using the ISO 1 connector and not ISO 2, connections are the same as for a Model VCP-6.

2.2.5.1 ISO 2 Cable Notes

♦ The ISO 2 cable should only be installed in addition

to the ISO 1 cable. Also, if you install and activate this cable, you cannot install and activate any IFB option cables.

♦ Connect the desired priority connector to J331 on the

main board. Connect the tally connector to J332.

♦ Set DIP switch S1-4 to the on position to activate the

ISO 2 connector*. (You should already have set DIP switches S2-4 and S2-6 to the on position to activate the ISO 1 connector.)

2.3 DIP Switch Settings

Table 3. DIP switch S2 settings

Unless you are using the 803 for IFB or ISO operations, you will probably not need to change any of the DIP switch settings. However, briefly review the tables below and make any required or optional changes before proceeding. Figure 4 showsthe locations of the DIP switches. Access the switches by removing the 12 screws securing the top cover.

Switches that are grayed-out in the tables require a reset after changing, and will cause any setup-mode programming to be erased. All other switches do not require any reset. See "Resetting the 803", page 19.

If you activate any of the DIP switches for the IFB or ISO connectors on the back panel, change the front panel button inserts as described on the next page. Otherwise, proceed to "Setting the Key Code Switch", page 17.

2.6 Setting the Key Code Switch

KEY

The key code switch on the back panel controls access to the user-programmable setup mode features. (The setup mode features are described starting on page 43.) Key code switch settings are as follows:

0: No access permitted (no one can program the 803) 1-9: User must enter this number before accessing setup mode A-F: No restrictions on access to setup mode (default)

Note: The key code switch has a stop at the 0 setting. Do not attempt to rotate the switch through 0 to F.

To restrict access, select one of the settings 0 through 9. Otherwise, leave the setting in the default position. If you change the switch setting, the new setting will take place immediately. Note that if you select the 0 position, you will need to gain access to this switch if you ever need to change any 803 programmable features.

CODE

2.5 Front Panel Button Inserts

The default setting for the front panel buttons is 12 conference intercom lines, with one talk and listen button pair for each line. This configuration applies to both 2-wire and 4-wire conference lines. If ISO or IFB options are installed, the front panel button configuration may be changed by installing different inserts from the supplied button insert sheet. Or, you can make your own custom inserts. Figure 7 summarizes the button usage for the various option configurations.

2.7 Resetting the 803

Prior to mounting the 803, perform a power-up reset.This will allow any DIP switch changes to take effect, and it will allow you to verify the operation of the front panel displays. To perform the power-up reset, simply plug in the power supply module.

At the start of reset, the front panel buttons will light in sequence. Then one listen button and one keypad button will light simultaneously to display the version number. The listen button displays the high digit and the keypad button displays the low digit. For example, if the LISTEN 5 button and the "7" button on the keypad are both lit, the version number is 5.7.

After the version number is displayed, the currently selected chime tone (if any) willsound. This is the tone that you will hear for incoming call announcement. (You can change this tone or turn it off. See "Chime Select Setup". page 46.) At this time, the SPK ON button will also light and remain on.

A warm reset only occurs underthe followingconditions:

♦ At power up if DIP switch S1-7 is set to the off posi-

tion AND NO HARDWARE DIP SWITCH SETTINGS HAVE BEEN CHANGED ANDTHE BACKUP BATTERY IS FUNCTIONING CORRECTLY. (DIP switches that affect hardware opera-

tion are grayed-out in Tables2 or 3 , page 16.)

♦ When the user forces a warm reset during normal op-

eration (see below) AND NO HARDWARE DIP SWITCH SETTINGS HAVE BEEN CHANGED AND THE BACKUP BATTERY IS FUNCTIONING CORRECTLY.

Forcing a cold reset

Simultaneously press and hold the talk 1, 5, and 9 buttons and the listen 2 button. Then, release the talk buttons while continuing to hold the listen 2 button. After the front panel lights begin to cycle release the listen 2 button.

Note: The rest of this page provides a detailed explanation of the reset operation. You may skip this and proceed to "Mounting the 803" on the next page; however, note that changes to DIP switch settings after you have programmed the 803 (using setup mode, as described starting on page 43) could erase your programmed settings.

The 803 has two reset modes: cold reset and warm reset. A cold reset restarts the 803 and erases all setup mode programming. All front panel buttons are turned off (except the SPK ON button, which always starts up in the on position). A warm reset restartsthe 803 and resets all front panel buttons to the positions they were in before the reset was initiated.

A cold reset occurs under the following conditions:

♦ DIP switch S1-7 is set to the on position and the 803

is powered up.

♦ The user forces a cold reset during normal operation.

(See "Forcing a Cold Reset", below.)

♦ The user changes any of the DIP switches that are

grayed-out in Tables 2 or 3 (page 16) and then performs a cold or warm reset by any means.

Forcing a warm reset

Simultaneously press and hold the talk 1, 5, and 9 buttons, then release all 3 buttons.

2.8 Mounting the 803

2.9 803 Connections

Note: If the mounting location for the 803 provides access to the back panel controls and connectors, you should be able to mount the 803 at this time. Otherwise, perform the connections and adjustments as described in the following sections before mounting the 803.

The 803 mounts in any standard equipment rack or bay and occupies 2 rack spaces (3.5 inches high). Depth is

10.5 inches behind the front panel. Allow an additional 2 to 3 inches for connectors.

If the 803 will be used with a VCP-6/VCP-12 ISO Panel or a 4001/4002 IFB Panel, it is generally located within easy reach of these devices. General consideration should also be given to the visibility of the controls and indicators from the operator's position to avoid eye or neck strain during extended usage and to assure unobstructed vision of other personnel or equipment. If necessary, discuss the positioning of the 803 and related components with personnel who will have to use them to assure the best setup. Once the 803 has been mounted, you should be ready to connect it to the intercom system. Proceed to the next page.

Refer to the connector pin-out tables and notes on the following pages for information about each connector. For examples of connector usage, refer to the diagrams following the connector pin-out tables. After you connect the 803, you may have to configure one or more features prior to operation. See "Setup Mode", starting on page 43 .

Intercom Audio

By default, 803 channels 1-12 are set for 2-wire bilateral operation with nulling. This may be modified forselected channels. See "2W/4W Setup", page 43 for further details. The 803 uses a balanced configuration for 2-wire operation. The 803 channels can be connected to either balanced or unbalanced intercom stations or channels. However, when making unbalanced connections, the noise immunity of the balanced 803 channel will be compromised, and it is best to not distribute that channel over cabling to other points in the intercom system. If you are connecting the 803 to an unpowered (dry) intercomchannel, terminate that channel at one and only one point by connecting a 200 ohm, 1/4-watt resistor across the intercom channel. If you are connecting a powered channel, termination is usually accomplished by the power supply. The 803 has built-in dc isolation, and so it is not necessary to use isolation capacitors when connecting to a powered intercom channel.

Talk Ke ying Signal Outputs

The 12 talk keying signal outputs are activated by the 803's talk buttons. These outputs may be used to activate external devices such as relays. See "Using the Talk Keying Outputs", page 34.

Program 2

For a description of the program inputs, see this topic on page 22.

Applications for J101

J101 may be used in several ways:

♦ Connecting to a TW intercom system using an RTS

Model 4012 System Interconnect Panel. An application is illustrated in Figure 15, page 35.

♦ Connecting to a TW intercom system using an RTS

Model 862 System Interconnect Panel. An application is illustrated in Figure 16, page 36.

♦ Direct interconnection of several 803 Master Stations.

An application is illustrated in Figure 17, page 37.

♦ Direct connection to intercom stations and other

audio inputs and outputs. Use an RTS Model 4024 Connecting Block or equivalent to break out the connections. The pin numbers on the 4024 Connecting Block correspond to the pin numbers on the J101 connector.

2.9.2 J102 Connector

Table 5. J102 connector pin-out

Relay Outputs

Each of the 6 internal relaysmaybe assigned for activation by most of the front panel buttons.See "Relay 1 Through Relay 6 Setup", page 49. The relays can be used for any audio or low-current switching requirements. For each relay, the normal closed contact acts like a simple closed switch (shorted to common) when the assigned front panel button is not on, and the switch contact opens when the button is activated. The normal open contact operation is the reverse of the normal closed contact. The two common connections for each relay are electrically identical. All relay connections are electrically isolated from the rest of the 803 circuitry. Relayconnections are also available at J108, page 28.

External Switch Contact Input (XSW)

A switch may be connected between pins 13 and 38 for remote operation of a front panel button. By default, switch contact closure will turn on the MIC ON button.To activate some other button, see "External Contact Setup", page 46. The XSW connection is also available at J108.

Program Inputs

Program inputs 1 and 2 are balanced, line-level audio inputs. Nominal input levelis 0 dBm. Balanced or unbalanced sources may be connected, but use normal precautions when connecting an unbalanced source (use shielded cabling, keep leads short, avoid routing wires near high voltage etc.). The program 1 and 2 inputs are adjustable via the PGM 1 and 2 trimmers on the front panel, and they may be assigned to either right or left headphones or the internal speaker via front panel programming. The program 1 pins of J102 are electrically identical to the program 1 pins of J111; the program 2 pins of J102 are electrically identical to the program 2 pins of J101, J105 and J111. For each program source, use only one connect point.

Channels 13 and 14

J102 provides access to channels 13 and 14, which do not normally have front panel buttons assigned. Channel 13 is reserved when the Model 803 is configured for Model 4001 IFB emulation. Both channels 13 and 14 are reserved when the Model 803 is configured for Model 4002 IFB Station emulation. If one or both channels are not used for IFB, they may be used as 4-wire channels. Use the "Bilat" pins for output and the "Listen input" pins for input. See "Bilat Select Setup", page 44, to assign front panel buttons to use the channels. Note that there is no provision for call signaling, mic-off signaling or keying output signals on these channels.

2.9.8 J108 Connector

Table 11. J108 connector pin-out

Relays and External Switch

The relay and external switch connections at J108 are electrically identical to those at J102. See "J102 Connector", page 22.

External ISO Connection

For external ISO, the 803 is used with an externalVCP panel located adjacent to the 803. Activating any of the ISO buttons on the external VCP panel sends a control signal to the 803 which causes all active talk channels to deactivate. The 803's microphone audio is then output at the bilat 15 pins on the J108 connector. This audio output is connected to the audio input of the VCP, which then sends it to the ISO system.

To connect external ISO:

Connect J108, pin 13 of the 803 to TB2, pin 2 of the VCP; connect J108, pin 25 to TB2, pin 3. Thisis the audio output connection from the 803 to the VCP.

Connect J108, pin 12 of the 803 to TB4, pin 4 of the VCP; connect J108, pin 24 to TB4, pin 3. This is the control input connection from the VCP to the 803.

Set DIP switch S2-6 to ON; S2-5 to ON or OFF as desired; S2-4 to OFF. For DIP switch details, see page 16.

Bilat 15

As previously described, bilat 15 can be used for ISO. If ISO is not required, bilat 15 can be used asa 2-wire intercom channel, or for audio output or input. Note that there is no provision for call signaling, mic-off signaling or keying output signals for bilat 15. To assign talk andlisten keys to use bilat 15, see "Bilat Select Setup", page 44. Note that there is no LISTEN control on the front panel for bilat 15. Adjust the listen level at the "R ISO" trimmer on the back panel. Adjust nulling at the "N ISO" trimmer on the back panel.

2.9.9 J109 Connector

Table 12. J109 connector pin-out

J109 can be used to connect to a computer or terminal for remote access and control of the 803. Use a standard RS232 cable (not null modem). Default RS232 port settings are 2400 baud*, 8 data bits, 1 stop bit and no parity. No handshaking is used. You can send commands to do any of the following:

♦ operate all front panel buttons or read their settings ♦ inhibit manual operation of front panel buttons ♦ read the settings of all DIP switches ♦ read and modify the 803's programmable memory ♦ operate all relays, talk/listen gates and key lines inde-

pendently of button positions

♦ initiate a reset (warm or cold) ♦ request notification upon operator initiation of reset ♦ send a command upon operator initiation of any func-

tion, front panel or DIP switch change

Command Structure

Most commands generally consist of 3 parts: a one- or two-character command letter, followed by a numeric modifier, followed by an operator. Commands which perform memory operations are structured as follows: a oneor two-character command letter, followed by a memory location, followed by a memory operator. If the memory operator modifies memory, it will be followed by one or more bytes of information to be sent to memory. All commands must be followed by a carriage return. All commands, except memory load commands, are limited to 128 characters in length.

Error Handling for the RS232 and RS485 Ports

Upon detection of an error in a command, the 803 will typically ignore the command and send out an error message consisting of the letter E along with a 2 digit code as follows:

E00 syntax error E01 output buffer overflow E02 unrecognizable command E03 Unrecognized operator (+, - or ? expected) E04 numeric modifier out of range E10 RS-232 framing or parity error E20 RS-422/485 framing or parity error

Note: Relays are updated every time a button is pushed or released. This means, for example, that if the host computer turns on a relay, it may be turned off the next time the 803 operator pushes any button. Keying output signals and gates may also be affected if the operator pushes the button associated with that key or gate.

2.9.10 J110 Connector

If desired, an external speaker may be connected and used in place of the internal speaker. Connector insertion causes the internal speaker to disconnect.

An external dynamic-mic headset with stereo headphones can be connected at the back panel rather than at the front panel DYN-MIC HEADSET connector. Note thatthese two connectors are not wired in parallel, but are separate circuits. Set the mic input sensitivity for the external dynamic mic at the EXT HM trimmer on the back panel. To activate the external dynamic-mic input, see "Mic Select Setup", page 48.

External Panel Microphone

An external panel microphone can be connected at the back panel rather than at the panel microphone connector at the upper-right of the front panel. Note that these two connectors are not wired in parallel, but are separate circuits. Set the mic input sensitivity for the external panel microphone at the EXT PM trimmer on the back panel. To activate theexternal panel microphone input, see "Mic Select Setup", page 48.

2.9.13 J201 Connector

J201 accepts a an electret condenser type panel microphone. Any microphone installed at this connector is referred to as the internal panel microphone (IPM). By default, the IPM is active when the PANEL ON button is in the on position. To change this, see "Mic Select Setup", page 48. The IPM gain is adjusted via the IPM trimmer on the back panel.

2.9.14 J202 Connector

J202 accepts a stereo, dynamic-mic headset. The microphone for any headset connected at J202 is referred to as the internal headset microphone (IHM). By default, the IHM is active when the PANEL ON button is in the off position. To change this, see "Mic Select Setup", page 48. The IHM gain is adjusted via the IHM trimmer on the back panel. The standard 803 uses a 5-pin connector for J202. This connector is used for headsets without a mic switch. The 6-pin version accepts a mic switch input which activates the MIC ON circuit.

2.9.16 Miscellaneous Connections

2.9.16.2External ISO

2.9.16.1Local IFB

Any of the intercom channels 1-12 can beconverted into a local IFB channel. (Not applicable to channels 13-15). A local IFB channel normally sends a program feed to a remote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the program feed and then talk to the remote listener. Three sources can be selected for the program feed: either the program 1 or 2 inputs, or that channel's 4-wire input (if the 4-wire option is installed).

To use an intercom channel for local IFB:

1. Set the intercom channel for local IFB operation and select the desired program source: see "Local IFB Setup", page 47. Note: Youcan only use the program 1 or 2 inputs unless the 4-wire option is installed.

2. Connect the intercom channel to the remote listener's station. When connecting both local IFB channels and standard intercom channels to the 803, it may be convenient to usesplitters. An example for 2-wire applications is shown in Figure 22, page 42. For a 2wire IFB channel, use the appropriate pins at the J101 connector, page 21. (Note: the 2-wire channels are normally used for bi-directional audio. In this case, however, you will be using the channel for audio output only.) For a 4-wire channel, use the appropriate talk audio output pins at J105, page 26.

External ISO connection was discussed on page 28.

2.9.16.3Using the Talk Keying Signal Outputs

The 12 talk keying signal outputs at J101 may be used to activate externaldevices by pressing the associated talk key. A typical configuration using a relay is shown in the figure below.

Note: Since the 803 uses Darlington outputs for the talk keying signals, the "on" state for the outputs may not pull sufficiently close to ground for use as a CMOS or TTL logic control output. Some type of external signal conditioning circuit is recommended.

3. Connect the program source. For both 2-wire and 4wire IFB, you may use either program 1 or 2 connected at any one of the following points:

Program 1

J102: page 22 J111: page 32

Program 2

J101: page 21 J102: page 22 J111: page 32

If you are using a 4-wire channel for IFB, instead of using the program 1 or 2 input you may connect program input directly to the 4-wire listen input of the channel that you are using for IFB output.

4. If desired, label the talk button for the new IFB channel to distinguish it from a normal talk button.

5. For local IFB button operation see page 55.

Figure 21. An application showing the use of both 2-wire and 4-wire circuits. Note that in this e xample, the 4-wire talk outputs use the 2-wire connector (J101).When a channel is operated in 4-wire mode, the 4-wire talk audio outputs from the 803 use the 2-wire bilats, which are bi-directional, as outputs only. The 2-wire bilat connections are available at both J101 and J105.In this application, the 4-wire talk outputs are connected using J101.The only reason for doing this is to also provide access to the keying outputs of the 803.For example, it may be necessary to key a radio transmitter when talking to it.If you only need audio input/output for 4-wire circuits and do not need to use the keying signals, you can eliminate the 4024 used for 2-wire breakout and just use one 4024 for 4-wire breakout.

3.2 Entering Setup Mode

1. If a key code was assigned during installation (page 17) first enter that code on the keypad. Otherwise, skip this step and go directly to step 2.

2. Press and hold the CALL & SETUP button for about 3 seconds. It should flash brightly during this time. When setup mode activates, the CALL & SETUP button will become brightly lit. Also, all buttons that immediately access setup features will begin to flash dimly.

3. Tap any flashing button to access its setup feature.

Note: Select a setup feature within about 13 seconds after entering setup mode. Otherwise, the 803 will automatically return to normal operating mode. Once a feature has been selected the 803 will remain in setup mode until you exit.

4. To exit setup mode at any time,tap CALL & SETUP again.

The following paragraphs describe how to use all of the setup features that are named on the front panel. The features are listed in alpha-numeric order.

3.4.1

See "2W/4W Setup", below.

3.4.2

Each intercom channel may be set for 2-wire operation, 4wire operation, or both. For 2-wire operation, nulling may also be optionally turned on or off. Thus, the intercom channels may be individually programmed to operate with a variety of inputs and outputs. For example, 2-wire operation won't work with a typical 2-way radio, which often requires a 4-wire, unbalanced connection. RTS "TW" belt packs and intercom channels, of course, operate in 2-wire mode, and nulling is normally activated when connecting to TW devices.

Default setting: all channels set for 2-wire operation with nulling

Select 2-wire/4-wire operation for selected channels as follows:

In addition to the 12 regular intercom channels which can be configured for either 2-wire or 4-wire operation, the 803 has three extra audio channels, channels 13 through 15, that don't havetalk and listen buttons associated with them. Channels 13 and 14 are 4-wire-only channels. Channel 13 TALK is reserved for IFB use when DIP switch S13 is set to the ON position ( page 16). This switch selects Model 4001 IFB panel emulation when the optional IFB 1 connector is installed. Channel 14 TALK is reserved for IFB use when DIP switches S1-3 and S1-4 are set to the ON position (for Model 4002 emulate using both the IFB 1 and IFB 2 connectors). Channel 15 is a 2-wire-only channel. This channel is reserved for ISO use when DIP switch S2-6 is set to the ON position. (Note: the nulling adjustment for channel 15 is the "N ISO" trimmer on the back panel. See "ISO Channel 15 Adjustments", page 51.)

4 Adjustments

4.2 Front Panel Adjustments

4.1 Back Panel Adjustments

4.1.1 Microphone Level Adjustments

There are 4 trimmers to adjust input gain for the various microphone inputs. Before adjusting the gain set the MIC ON button to the on position. Also, set the PANEL ON button to the on position for a panel microphone or to the off position for a headset microphone. Note that by default the PANEL ON button selects the internal panel microphone in the on position and the internal headset microphone in the off position. To changethis see "Mic Select Setup, page 48.

HM (Internal Headset Microphone)

This trimmer adjusts the gain for a headset microphone connected at either the DYN-MIC HEADSET or CARBON-MIC HEADSET connector.

PM (Internal Panel Microphone)

This trimmer adjusts the gain for a panel microphone connected at the front panel of the 803.

4.2.1 VOX PM / VOX HM Adjustment

Note: You must enable the VOX feature to make this adjustment. See VOX Enable Setup", page 50.

Note: The VOX level adjustment is affected by the settings of the "HM" and "PM" trimmers on the back panel. Make sure those trimmers are correctly set before proceeding. See "Microphone Level Adjustment", page 51.

Set the VOX level as follows:

1. Turn on a talk button.

2. Make sure the correct microphone is selected: the PANEL ON button should be on for a panel microphone and off for a headset microphone.

3. Speak into the microphone. If you are using a panel microphone adjust the VOX PM trimmer on the front panel so that the MIC ON button lights at the desired sound level; if you are using a headset microphone adjust the VOX HM trimmer to activate the MIC ON button.

EXT HM (External Headset Microphone)

This trimmer adjusts the microphone gain for a dynamicor carbon-mic headset connected at J111.

EXT PM (External Panel Microphone)

This trimmer adjusts the gain for a panel microphone connected at J111 on the back panel.

4.1.2 ISO (Channel 15) Adjustments

R ISO (ISO Receive)

This trimmer functions for channel 15 exactly like the front panel LEVEL controls function for channels 1-12. Increase or decrease this level as desired when channel 15 is receiving an audio input.

N ISO (ISO Null)

The null adjustment for channel 15 is the same as for any of the 12 regular intercom channels. See "Null Adjustment", at right.

4.1.3 USMB (Unswitched Microphone Balanced) Output Level Adjustment

Use this control to adjust the USMB output level at J111.

4. This completes the VOX level adjustment.Turn the talk button off.

4.2.2 PGM1 / PGM2 Adjustment

Use the PGM1 and PGM2 trimmers on the front panel to equalize any level differences between the two program inputs. You may also adjust both trimmers to raise or lower the range of the PROGRAM VOLUME control.

4.2.3 LAMP DIM Adjustment

Adjust this trimmer to set the brightness of the front panel lamps as desired.

4.2.4 Null Adjustment

When you are using a channel in 2-wire mode, that channel should be balanced, or nulled, so that the outgoing signal from your microphone is not fed back into your speaker and/or headphones. Any residual signal that is fed back will sound like sidetone (see the separate paragraphs on "Sidetone Adjustment", below). However, unlike sidetone, which is heard only in the headphones and will be a constant level no matter which channel you are talking to; the residual feedback from an improperly nulled 2-wire channel will be heard both in the speaker and headphones, and it will vary from channelto channel depending on the degree of imbalance in each channel.

The null adjustment is related to the overall impedance of the intercom channel, and is thus to a certain degree influenced by the number of devices connected to that channel. Therefore, best nulling will be achieved after all stations have been connected to the intercom channel. You can perform the null adjustment using the panel mic and speaker (recommended method) or a headset. If a headset is used, you must first set the sidetone trimmer to minimum.

Note: Each channel can be set for either 2-wire or 4-wire operation, and nulling can be turned on or off for each 2wire channel. (See "2W/4W Setup", page 43 for further information.) By default, all channels are set for 2-wire operation with nulling. If nulling has been turned off for a channel, or that channel is operated in 4-wire mode, the following adjustment will have no effect.

Perform the null adjustment as follows:

1. Activate the MIC ON button.

2. Select the desired microphone source. Activate the PANEL ON button if you are using a panel microphone, or tun the PANEL ON button off if you are using a headset. Also activate the SPEAKER ON button if you are using the speaker.

amount of sidetone is necessary for natural-sounding communication.

Note: If one or more channels are being operated in 2wire mode with nulling, make sure those channels are properly nulled before setting the sidetone level.

1. Set the MASTER VOLUME and PROGRAM VOLUME controls to minimum.

2. Activate the MIC ON button.

3. Set the PANEL ON button to the off position.

4. While speaking into the headset microphone, adjust the SIDETONE trimmer so that your voice is heard in the headphones at the desired level.

5. This completes the sidetone adjustment.

3. Activate the talk and listen buttons for the first channel that you want to adjust. If there is feedback, reduce the MASTER VOLUME.

4. While talking into the microphone, adjust the null trimmer for that channel to minimize your own voice level in the speaker or headphones. As you minimize, or null out, your own voice level you can increase the MASTER VOLUME level, aswell as the individual LEVEL control for that channel, to help you hear better when a good null has been achieved.

Note: The null trimmers for channels 1-12 are located on the front panel. Since channels 13 and 14 are 4-wire only, no null trimmer is provided. The null trimmerfor channel 15 is located on the back panel and is identifiedas N ISO, since this channel is primarily used for ISO operation.

5. Repeat the adjustment for each remaining channel that is being operated in 2-wire mode.

6. This completes the null adjustment. If you will be using headphones with the 803, perform the sidetone adjustment after the null adjustment.

4.2.5 Sidetone Adjustment

The sidetone adjustment lets you set the level of your own voice in the headphones when using a headset. A certain

5.2 Momentary vs Latching Button Operation

Most front panel buttons feature both momentary and latching operation. For momentary operation, press and hold the button to turn it on, then release it to turn it off. For latching operation, tap a button to turn it on, then tap it again to turn it off. Latching operation can be used when you want to keep your hands free for other operations.

Note: Latching operation may be turned off for selected buttons. See "Latch Disable Setup", page 47.

5.3 Headset or Panel Mic/Speaker Selection

If you are using a headset, leave the PANEL ON button in the off position (unlit). You can setthe SPKR ON button (speaker on) to either on or off as desired.

You can defeat latching operation for a talk button. See "Latch Disable Setup", page 47.

You can lock a talk button in the on or off position. See "Button Lock Setup", page 45.

5.5 Listening to an Intercom Channel

To listen to a channel, activate its listen button in either momentary or latching mode. Adjust the MASTER VOLUME control to an acceptable listening level.

As you listen to intercom channels, you may notice that some channels are louder or softer than others. In this case, adjust the individual channel LEVEL controls at the bottom of the front panel. (There is no level adjustment for channels 13 and 14. Adjust the channel 15 level via the R ISO trimmer on the back panel.)

Note: Several options can be assigned to selected listen buttons to modify their standard operation:

You can setup a listen button to automatically turn on whenever the corresponding talk button is pressed. See "Talk Turns on Listen Setup", page 50.

If you are using an optional panel microphone along with the built-in speaker, set the PANEL ON and SPKR ON buttons to the on position.

Note: You may find it useful to lock either or both of these buttons in the on or off position. See "Button Lock Setup", page 45.

5.4 Talking to an Intercom Channel

1. Activate the MIC ON button.

2. Make sure the correct microphone is selected: the PANEL ON button should be on when you are using a panel microphone and off when you are using a headset.

3. Activate the talk button for the channel that you want to talk to. Press and hold the button for momentary operation. Or, tap the button to latch it in the on position for "hands-free" operation.

Note: Several options can be assigned to selected talk buttons to modify their standard operation:

You can setup a talk button so that it automaticallyactivates the MIC ON button. See "Instant Mic Setup", page 47.

You can setup a listen button to automatically turn off whenever the corresponding talk button is pressed. See "Talk Turns off Listen Setup", page 49.

You can setup a listen button to automatically turn on whenever there is an incoming call on that channel. See "Auto Listen Setup", page 44.

You can defeat latching operation for a listen button. See "Latch Disable Setup", page 47.

You can lock a listen button in the on or off position. See "Button Lock Setup", page 45.

5.6 Program Listen

After an acceptable listening level for the intercom system has been established, adjust the PROGRAM LEVEL control to establish an acceptable listening level for any program inputs that may be connected.

5.7 Receiving Call Signals

When another intercom station calls your station, you will hear the call chime tone, and the talk button for that channel will begin to flash. Activate the talk and listen buttons to communicate.

Note: Several options can be setup to modify the way incoming calls are received and indicated:

Incoming call signals may be disabled on selected channels. See "Call Disable Setup", page 46.

Selected talk and listen buttons may be setup to automatically activate on incoming call. See "Auto Talk Setup" and "Auto Listen Setup", page 44.

Any 1 of 3 chime tones, or no chime tone, may be selected for incoming call announce. See "Chime Select Setup, page 46.

Selected listen buttons may be setup to flicker as a caller talks to provide a visual cue of a call's origin. See "Caller ID Setup", page 46.

5.8 Sending Call Signals

To send a call signal on a specific channel:

5.10 Telephone Dialing with the Keypad

The 803 is capable of generating DTMF tones for dialing out on a phone line. If there is a telephoneinterface connected on an intercom channel, you can use the 803 keypad to dial out on that channel. The actual method that you use to access the phone line varies dependingon how the 803 is connected and the type of telephone interface being used. For example, your intercom system may be configured so that activating a talk button will pick up the telephone line, in which case the following procedure may be used. Some installations, however, may require some other action to pick up a telephone line, in which case you will need to do that before the following procedure.

1. Tap theasterisk button (*) three times. The keypad buttons will light to indicate that dialing mode is activated, and the CALL & SETUP button will flash to indicate that this is the key to press to return to normal mode. The talk buttons will also begin to flash.

1. Tap theCALL & SETUP button. It should begin to flash.

2. Within about 2-3 second, tap the talk button for the channel that you want to call. You should hear a chime tone, indicating that the call signal has been sent.
