12. IAM CONNECTIONS

The 12th step needed to install the ELI option applies only if an IAM was supplied. All connections to the IAM are made to connectors on the rear panel, as shown in Figure 36.

Power Supply

Connect a 19B803968P1 cable from the male 1x6-pin Molex connector on the back of the IAM (marked "POWER") to P801 on the repeater power supply, as shown in Figure 37. Note that the power supply end of the cable comes with pins attached to the wires, but no connector shell. These pins are to be inserted into the existing connector shell already connected to P801 on the power supply.

Figure 37 - IAM Power Supply Connections

For a power supply connected to a MASTR II or IIe repeater, remove the existing pins in pin positions 3 and 5, and tie back. Then insert the pin on the red wire into pin position 3 and the pin on the black wire into pin position 5.

PCM/Data Bus

Connect the PCM/Data bus cables as instructed in the previous section for the GTI units.

Alarm Outputs

The IAM provides three open-drain alarm outputs for the user to connect to an alarm system, if desired. These alarm outputs will go through indeterminate states during IAM power-up or reset. If the Active High output configuration is selected by setting DIP switch section 7 to the up position, all alarms will be active if the IAM loses power. Conversely, if the Active Low output configuration is selected by setting DIP switch section 7 to the down position, no alarms will be active if the IAM loses power. The standard ELI option does not provide a cable for this connection, but pin-out information is shown in Figure 38. Pins 7 through 10 are not used.

Printer RS-232 Port

For a power supply connected to a MASTR III repeater, insert the pin on the red wire into pin position 3 and the pin on the black wire into pin position 6.

A female 9-pin RS-232 serial printer port, labeled “PRINTER”, is provided in the rear panel of the IAM allowing you to connect a printer to keep real-time records of calls being placed on your system (a record is printed after each call ends). The proper baud rate for the port can
