7. Replace the top cover of the paging terminal and secure with screws.

8. Power-up the unit and let it complete its boot sequence (all lights have extinguished,

except the READY LED is on solid).

9. Access the Model 640 database and edit the Trunk Line Type database to setup a line

with multifrequency signaling. Then edit the Trunks database to enable the option on

the desired trunk. Refer to the Model 640 Operating and Programming Manual (Part

No. 025-9417) for details on how to edit these databases.

10. After the databases have been setup, reboot the Model 640 to initialize the MF

option.

No hardware adjustments are required for the MF decoder option.

PARALLEL PRINTER CARD

The printer option (Part No. 950-9758) enables a parallel printer to be connected to the Model

640. The printer provides a real-time hard copy of the system events (log file data). This is useful

for monitoring traffic and analysis of the system functions, throughput, and efficiency. The

printer records paging input and output, network link status, and ZLINK session activity.

Once the printer option is installed, all system activity is sent to the printer. Be sure to keep the

printer powered-up and loaded with paper to ensure that no events are missed.

Installation

Follow the steps below to install the optional printer card (Part No. 702-9359) into the Model

640 chassis.

CAUTION

Please exercise electro-static discharge (ESD) precautions when handling all parts.

1. Verify that all of the printer card jumpers are set appropriately. Figure 60 shows the

configuration and locations of the critical jumpers. (The jumpers should have been

set at the factory, but it is a good idea to double check.)
