INTERCONNECTING THE EQUIPMENT AE/LZB 119 1894 R1A

If COM3: Interrupt

Jumper JP3

“11” position

If any other RS-422 plug-in serial board is used the

following board configuration is recommended:

COM Port COM3

Port Address 3E8

Interrupt IRQ11

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

(see the following note). 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 6 or

the cable's assembly diagram (page 21) for wire color

coding. Also see Figure 7A.

NOTE

If cable 19B804083P3 is utilized and the PC is

equipped with a 3PXCC2A plug-in RS-422 board

(dual ports with DB-9 connectors), a field-

fabricated DB-9-to-DB-25 adapter must be

constructed and utilized as shown in Figure 7C.

In addition, cable 19B804083P3 is not compatible

with earlier plug-in RS-422 boards used with the

C3 Maestro console system. These earlier plug-in

boards are manufactured by ICS and included

model numbers RS422AT-P and RS422I-P. They

can be easily identified by the presence of two LED

indicators visible on the rear plate.

If cable 19B802083P3 is not used but RS-422 hook-ups

are required, see Figures 4 (or 5) and 7A 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.
