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.

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.
7
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.
8
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.)
9
1.1.5803 Compatibility with RTS Model 4000
IFB System and Local IFB
1.1.6Comparison 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.

2.2Option Cable Installation
2.2.34-Wire Option Cable Notes
2.2.1General 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)
2.2.2Back 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.
2.2.4IFB 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.

When you install an IFB or ISO option cable and set the
internal DIP switches as noted in the following paragraphs, specific front panel buttons will be reserved for
the installed option. The button insert sheet provides
standard button labels for these reserved buttons. See
"Front Panel Button Inserts", page 17 for details.
2.2.4.2 IFB 1 Cable Notes
♦ Connect the desired priority connector to J325 on the
main circuit board. Connectthe tally connector to J326.
♦ Set DIP switch S1-3 (page 16 ) to the ON position*.
DIP switch S2-8 may optionally be set to the on position if you want all talk buttons to automatically shut
off whenever any IFB button is activated.
♦ When installing button inserts for IFB 1 (page 17)
note that different buttons are used, depending on
whether or not another IFB or ISO connector is installed.
♦ Use a 50-pin cable to connect from the IFB 1 connec-
tor to a Model 4010 Central ElectronicsUnit. Typical
connections are shown in Figure 20, page 40. Refer
also to your Model 4010 Manual; if you are only using the IFB 1 connector and not IFB 2, connections
are the same as for a Model 4001 Control Station.
2.2.4.3 IFB 2 Cable Notes
♦ The IFB 2 cable should only be installed in addition
to the IFB 1 cable. If you install and activate thiscable, do not install and activate any ISO option cables.
♦ Connect the desired priority connector to J327 on the
main board. Connect the tally connector to J328.
♦ Set DIP switch S1-4 (page 16 ) to the ON position to
activate the IFB 2 connector*. (You should already
have set DIP switch S1-3 to the on position to activate the IFB 1 connector.)
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.)
♦ Install the button inserts (page 17).

2.3DIP 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.

2.6Setting 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.

2.7Resetting 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.
♦ The backup battery fails and any kind of reset by any
means occurs.

2.8Mounting the 803
2.9803 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 .

2.9.1 J101 Connector
Table 4. J101 connector pin-out
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.
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.

2.9.8J108 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.
Buttons and certain functions are numbered as follows:
1-12top row of buttons
13-24second row of buttons
25-40keypad buttons (left-to-right, top-to-bottom)
41external camera iso input
42external global reset tally #1
43external mic
44external global reset tally #2

57-68listen activity detectors
69special mute (on special order software)
70headset mic switch
71carbon mic switch
72external carbon mic switch
73vox detect
74external preset 3
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:
E00syntax error
E01output buffer overflow
E02unrecognizable command
E03Unrecognized operator (+, - or ? expected)
E04numeric modifier out of range
E10RS-232 framing or parity error
E20RS-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.

2.9.13 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.

2.9.16.1Local 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:

J111: page 32
Program 2
J101: page 21

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.

with optional IFB1 and ISO1 connectors.Six front panel buttons emulate a Model 4001 IFB panel, and six emulate
a V CP-6 ISO panel. Each 803 may send IFB selectively to any of the 4 talent locations or to the stage announce
output of the 4010. Each 803 may also selectively ISO any of the six cameras. Note that in this configuration, channels 1 through 6 are still available for use as 2- or 4-wire intercom channels.Also, since the IFB2 option is not installed, Bilat 14 is available as an extra 4-wire intercom or audio I/O channel.
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.

3.2Entering 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.

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.

4Adjustments
4.2Front Panel Adjustments
4.1Back 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.
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.
51
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.
4.2.5Sidetone Adjustment
The sidetone adjustment lets you set the level of your own
voice in the headphones when using a headset. A certain

5.8Sending Call Signals
To send a call signal on a specific channel:
5.10Telephone 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
