Audio System Board

Mic Audio ALC Enable/Disable DIP Switch (S1)

DIP switch S1 on the Audio System Board is used to independently enable or disable each microphone's automatic level control (ALC) circuit. The switch has four (4) positions, one for each mic that may be connected to the Enhanced Audio Enclosure.

An Audio System Board ships from the factory with all mic audio ALC circuits enabled. As shown in Figure 2, this is accomplished by setting all four S1 switch positions to "ON" or "CLOSED". Table 2 lists each switch position and its corresponding microphone.

Normally, mic audio ALC should not be disabled. However, if required, disable a mic's ALC by setting the corresponding DIP switch position to "OFF" or "OPEN". See LBI-39100 for Enhanced Audio Enclosure disassembly and Audio System Board access instructions.

ENHANCED AUDIO ENCLOSURE

Normally, the Enhanced Audio Enclosure is configured at the factory for a standard C3 Maestro dispatch console system installation. This configuration includes setting a single 4-position DIP switch and programming all digital pots for nominal audio input and output levels. The DIP switch and digital pots within the Enhanced Audio Enclosure are located on the Audio System Board.

Digital Pots Settings

To provide computer-controlled level settings, the Enhanced Audio Enclosure's audio input and audio output circuits incorporate 256-position digitally-controlled potentiometers. These digital pots, located on the Audio System Board, allow adjustment of the Enhanced Audio Enclosure's audio levels via the PC. Adjustments include dispatcher-adjustable audio levels such as headset sidetone volumes and system-level adjustments such as line input and output levels to and from the CEC/IMC Digital Audio Switch.

With the exception of the dispatcher's headset sidetone volume adjustments, none of the digital pots pro vide volume adjustments for the speaker or headset earphone audio levels during normal dispatch operations. Speaker and headset volume adjustments are accomplished at the respective speaker or headset via mechanical pots. Also see the following note.

NOTE

Communication module volume changes at the C3

Maestro effect CEC/IMC CIM line output levels,

not the digital pots within the Enhanced Audio

Enclosure.

Fifteen (15) dual digital potentiometer chips (integrated circuits) are located on the Audio System Board for a total of thirty (30) individual pots; there are no mechanical potentiometers. All audio level adjustments are accomplished via software. See Table 3. A dispatcher may adjust the operator's sidetone digital pot using dedicated keyboard keystrokes <Alt> <Vol ↑ > and <Alt> <Vol ↓ > at the Dispatch Keyboard.

All of the digital pots initially power-up with the wiper in a 50% or centered position. The microcontroller on the Audio System Board then immediately loads each pot in accordance with its respective setting stored in a "working" area of a serial EEPROM chip on the board. The EEPROM also contains an unchangeable "default" digital pot storage area. When shipped from the factory, the working area matches the default area.

Digital pots may be adjusted using the C3 Maestro application program via one of its note cards. This function changes the settings stored in the EEPROM's working area. Normally, this note card function should only be accessed by the installation and/or service personnel. To change a digital pot's setting, the following procedure may be performed after the console's installation is complete and it has been powered-up:

1. From the Dispatch Keyboard, simultaneously press the <Alt> (common control function) and the # (on

numeric keypad) keys. "Digital Pot Num ber: ?" is displayed in the lower left-hand side of the C3 Maestro's display.

2. From the numeric keypad, enter the number of the digital pot to be changed. See Table 3. The digital pot's existing setting is displayed.

3. Press the ↑ (increase) or ↓ (decrease) key to change the current setting. Changes are saved in the EEPROM's working area as they are made.

4. Press <Esc> to exit.

SPEAKER ASSEMBLY

Normally, a Speaker Assembly used with the Enhanced Audio Enclosure is configured at the factory with its minimum v olume f eatur e ena bled and it s maximu m volume output power set to 2 watts. This configuration is accomplished by setting two positions on a 4-position DIP switch located on the Speaker Amp Board within the Speaker Assembly.

NOTE

The following information lists the normal factory

settings and the optional settings which are

available.

Speaker Amp Board

At each Speaker Assembly, a 4-position DIP switch identified as SW1 is located on the Speaker Amp Board. One position is used to enable or disable the minimum volume level feature. A second position allows setting of the maximum volume level to either 2 or 5 watts of output power. Factory settings are shown in Figure 3. These switches have no effect on hea dset earphone output le vels. Currently, the other two DIP switch positions on SW1 are not used.

NOTE

SW1 may have a tape seal placed over the switches

to prevent changes.

Minimum Volume Level DIP Switch (SW1 Position 1)

When SW1 position 1 is "OFF" or "OPEN", the minimum volume level feature is enabled. This is the factory setting. With this setting, audio from the speaker cannot be completely turned off by rotating the volume control on the Speaker Assembly's front panel fully counterclockwise.

Specifically, with the volume control fully counterclockwise and a nomimal audio level of 436 millivolts rms at a frequency of 1kHz from the Enhanced Audio Enclosure, the audio output level from the speaker will not drop below approximately 0.38 milliwatts or 55 millivolts rms across the 8-ohm speaker. This wattage figure assumes SW1 position 2 is also "OFF" or "OPEN", selecting the 2-watt maximum volume level. With SW1 position 2 selecting 5-watts, the minimum volume level is approximately 1.25 milliwatts or 100 millivolts across the 8ohm speaker.

CEC/IMC INTERCONNECTIONS

The C3 Maestro console interfaces to the CEC/IMC via a full-duplex serial control data link and a 4-wire audio connection for the select audio and microphone link. In addition, each unselect speaker at the console requires an additional 2-wire connection from the CEC/IMC. Also, if the console is interfaced to a Call Director for Call Director telephone patch operations, an additional 4-wire audio link between the C3 Maestro and the CEC/IMC is required. See Figures 1 and 6 and Table 5.

As shown in Figures 1 and 6, all CEC/IMC interconnections are made via Concentrator Cards. These cards are located at the back of the CEC/IMC cabinet. Control data connections are made via Data Concentrator Cards and audio connections are made via Audio Concentrator Cards. Typically, as shown in Figure 6, these connections are extended out of the CEC/IMC cabinet via Telco cables and terminations are actually made at punch blocks located external of the CEC/IMC cabinet.

CEC/IMC Concentrator Card pin-out details are listed on the customer-specific system documentation print-outs. These print-outs are included with the CEC/IMC when it ships from the factory. See the CEC/IMC Digital Audio

Control Data Link

Overview

Either an RS-422 (four-wire) or an RS-232 (three-wire) full-duplex serial control data link may be employed between the console and the CIM within the CEC/IMC. Since RS-422 interfacing is superior to RS-232, PCs used within the C3 Maestro console application normally ship from the factory with an RS-422 serial port provided for this purpose. RS-232 has poorer noise performance than RS-422 and therefore, it should never be used for cable runs more than 50 feet (15.2 meters) in length. RS-422 connections may be up to 4000 feet (1219 meters) in length.

If required for a remote console installation, full-duplex 4-wire data modems can be used between the C3 Maestro and the CEC/IMC. Typically, the PC-to-modem and modem-to-CEC/IMC interconnections must be made via RS-232 interconnections since many data modems do not provide RS-422 hook-ups. These RS-232 interconnections should also not exceed 50 feet. See the following subsections for additional remote console wiring and modem configuration details.

At the C3 Maestro, RS-422/RS-232 serial control data connections terminate at the PC's serial COM port. Normally, COM1 is utilized for CEC/IMC interfacing. This serial port is normally provided by a plug-in RS-422 board inside the PC as described in the following section.

RS-422 Interfacing (Co-Located Hook-Ups)

In most cases, the PC used in the C3 Maestro console system is not equipped with a main ("mother") board RS-422 capable serial COM port. Therefore, a plug-in RS-422 capable interface board is installed in one of the PC's internal expansion slots and utilized for CEC/IMC interfacing. If the plug-in RS-422 board's serial port is configured as COM1 (normal factory configuration), the PC's main board COM1 port is disab led to p revent conflicts. Likewise, if the plug-in RS-422 board's serial port is configured as COM2, the PC's main board COM2 port is disabled. Depending upon the type of PC used, disabling of the main board's COM port is done via either a DIP switch, jumper, or a BIOS set-up program. For COM port enable/disable configuration details, refer to the section entitled "

Normally, a pre-wired 100-foot (30.5 meters) cable is supplied with the console equipment package for RS-422 control data interconnections between the CEC/IMC and a co-located C3 Maestro console. The cable's part number is 19B804083P3. It has a female DB-25 connector on one end for mating to the RS-422 male DB-25 connector at the PC. The other end is "pig-tailed" (not terminated) so the cable's 24-gauge solid wires can be punched down to the correct terminals at the required CEC/IMC punch block.

If using the supplied control data cable, mate its female DB-25 to the PC's RS-422 male DB-25 connector, route it to the CEC/IMC, shorten the cable as required, and punch the wires to the correct terminals. See Table 4 or the cable's assembly diagram near the end of this manual for wire color coding. Also see Figure 6A and the cable’s assemble diagram on page 36.

RS-232 Interfacing (Remote Console Hook-Ups Via 4-Wire Modems And RS-232 Interconnections)

When the C3 Maestro is installed at a remote location from the CEC/IMC, a serial control data link must be established via RS-232 connections and 4-wire full-duplex 9600 baud data modems. Since the C3 Maestro requires a dedicated or continuous serial link (non-dial-up), a 4-wire leased line (or equivalent) meeting 3002 data grade specifications must be employed between the CEC/IMC and the C3 Maestro in a remote console installation.

If cable 19B802083P3 is not used for RS-422 hook-ups, see Figures 4 and 6A and/or the manufacturer's documentation for COM port connector pin-out details. Fabricate a cable as required and then use it to interconnect the C3 Maestro's RS-422 control data COM port to the appropriate CEC/IMC Data Concentrator Card as required. Shielded cabling is recommended. Per RS-422 specifications, cable length should be limited to 4000 feet (1219 meters) or less.

Figure 6B shows typical control data interconnections for a remote console installation using RS-232 connections and full-duplex 4-wire modems. At the CEC/IMC Data Concentrator Card, RS-232 connections are made at J13, not J12. Observe all notes listed in the figure if wiring an installation of this type. Recommended modem settings are:

Audio Links

Audio Concentrator Cards at the back of the CEC/IMC cabinet provide audio connections at the CEC/IMC. Like the control data connections, audio connections are normally extended out of the CEC/IMC cabinet via Telco cable(s) and line terminations are actually made at punch blocks. See Figure 6A. See the customer-specific system documentation print-outs for Concentrator Card connector pin-out details.

Table 5 shows line requirements between the C3 Maestro and the CEC/IMC for each audio input or output 2wire 600-ohm twisted pair. Note that two (2) Enhanced Audio Enclosure output pairs, Line 2 out and Line 3 out are never used. These audio output lines are provided for future expansion use.

At the C3 Maestro, audio connections terminate at the DB-25 connector on the Enhanced Audio Enclosure's rear panel. This connector is labeled "LINES 1-4" . Its pin-out is shown in Figures 5 and 6A and Table 12. It has female contacts; therefore, the required mating connector is a male DB-25.

Normally, a pre-wired 100-foot (30.5 meters) cable is supplied with the console equipment package for audio interconnections between the Enhanced Audio Enclosure and the CEC/IMC. This 8-pair shielded cable's part number is 19B804083P2. It has a male DB-25 connector on one end for mating to the Enhanced Aud io Enclo sure's " LINES 1-4" female DB-25 connector. The other end is "pig-tailed" (not terminated) so the cable's 24-guage solid wires can be punched down to the correct terminals at the required CEC/IMC's punch block.

Speakers (if used)

Desktop and rack-mount Speaker Assemblies used with the Enhanced Audio Enclosure each basically consist of mechanical hardware, one or more speakers, audio amplification circuitry, and a volume control potentiometer. The mechanical hardware may be of several different varieties providing either desktop speaker operation in the form of a self-contained single-speaker case or a rack-mount version in the form of a standard 19-inch EIA rack mount assembly. The 2-speaker rack-mount versions are generally

LBI-39101 INTERCONNECTING THE EQUIPMENT

assembled with one amplified speaker in the far left-hand position (select speaker), one amplified speaker in the far right-hand position (unselect speaker) and blank panels installed in the two center positions. Four-speaker consoles are generally equipped with two separate 2-speaker rack mount assemblies.

Install or mount each Speaker Assembly in a suitable location and then interconnect it to the Enhanced Audio Enclosure using cable P29/5010150000 (350A1371P29). This cable is 9 feet (2.74 meters) in length. It is identical to the cable that interconnects the PC's serial COM port to the Enhanced Audio Enclosure. Mate the cable's female DB-9 connector to the appropriate male DB-9 connector on the Enhanced Audio Enclosure's rear panel. These male connectors are labeled "SEL SPKR" (select speaker), "UNSEL

SPKR1" (first unselect speaker), "UNSEL SPKR2" (second unselect speaker) and "UNSEL SPKR3" (third unselect speaker). Connect the

other end of the cable to the female DB-9 connector at the respective Speaker Assembly. If necessary, see Tables 18 and 19 for DB-9 pin-outs.

Relay Outputs (if used)

Form-C relay contacts (single-pole double-throw) are available from the Enhanced Audio Enclosure for external device control. Contact connections are made at the screwterminal type terminal block on the rear panel labeled "RELAYS". Even though these relays are also controlled from the console’s dispatch keyboard, they are not the same as and they should not be confused with the relays within the CEC/IMC utilized for auxiliary I/O interfacing.

As shown in Table 25, the first relay (relay 1) is activated when the console is keyed (PTTed). During the key, the relay's common and normally-open contacts close and its common and normally-closed contacts open. The second relay's (relay 2) common and normally-open contacts close while <Alt><F10> is depressed at the Dispatch Keyboard. Like the first relay, this relay's action is considered "momentarily" as it is only in the active state when the <Alt><F10> keys are depressed. The third relay's (relay 3) contacts toggle open/close at an <Alt><F9> keystroke from the Dispatch Keyboard. The other relays are not supported by software.

As required, connect the relay contact outputs to external equipment. See Table 25 and Figure 9. Specified contact rating for all relays is 0.75 amps at 26 Vdc. Open contact isolation is specified to 500 Vrms at 60 Hz. Isolation between any relay terminal and the Enhanced Audio Enclosure's ground is also specified to 500 Vrms at 60 Hz.

Call Director (if equipped)

As shown in Figure 1, all C3 Maestro-to-Call Director

interconnections at the console are made at the Enhanced Audio Enclosure's connector labeled "CALL DIR". A Call Director telephone patch also requires an additional 4-wire balanced line between the Enhanced Audio Enclosure and the console’s CIM within the CEC/IMC. At the CEC/IMC, CIM audio channel/line four (4) is used for Call Director interfacing. CD control data interfacing is handled over the existing RS-232/RS-422 serial control data interface between the PC and the CEC/IMC. Therefore, no additional control data link must be added to support Call Director patch equipment. Refer to Figures 1, 5, 6 and 10 for interconnection details and the following discussion on CEC/IMC line audio line requirements.

Console-to-CEC/IMC Audio Interconnections

All CEC/IMC line audio in to and out of a C3 Maestro

dispatch console system enters and leaves via the DB-25 connector labeled "LINES 1 - 4" on the Enhanced Audio Enclosure's rear panel. If the console is connected to a Call Director, Line 4 between the Enhanced Audio Enclosure and the CEC/IMC must be established for CD audio routing between the console and the CEC/IMC. In this case, the third unselect speaker audio is not available.

Serial Ports' Settings

Normally, the PC's COM1 serial port is utilized for CEC/IMC control data interfacing. The baud rate of this port may be set to operate at 19,200 or 9600. The 19,200 setting is recommended for all co-located console hook-ups. The 9600 baud setting is normally required when a data modem is employed between the console and the CEC/IMC in a remote console installation.

If necessary, use the Editor program to change the COM1 baud rate . Save the change to the hard disk drive. 19,200 baud is the factory (default) setting. See LBI-39056 for additional details. The CEC's/IMC's CIM has auto-baud sensing; therefore, no CIM changes are required when a baud rate change is made here.

Normally, the PC's COM2 serial port is utilized for Enhanced Audio Enclosure control data interfacing. In this case the port operates at 9600 baud. This setting is fixed in the PC's software and in the Enhanced Audio Enclosure's firmware. It cannot be changed.

Editor program version 5.0 (and later) includes a setting to select Enhanced Audio Enclosure (serial) or Logic Board (parallel) interfacing. When using an Enhanced Audio Enclosure, enable/verify serial operation as follows:

Call Director ID

Call Director ID is a secondary console ID number that is only used for Call Director telephone patch operations. The default value for this ID is zero (0) − no Call Director. Valid Call Director ID range is 1 - 16382. The zero setting should not be changed unless a Call Director is attached to the console and the console will be used for Call Directo r patch operations. The ID resides in the unit/console ID space and it should therefore be a unique (unused) ID number. Console ID and Call Director ID should never be

identical.
