INSTALLATION

Install Module

Disconnect power to the shelf. Install the module in the proper slot

in the equipment housing by sliding the module along the guide

slots, then firmly seating connector in its receptacle.

Checkout

Checkout of the 44202 202 Compatible Modem is done by setting

the transmit and receive levels and testing the analog and digital

circuit sides using the digital and analog loopback functions. Refer

to Fig. 5 (in the Operation section of this manual) and the

following procedure.

ROCEDURE

Alignment

Action: Configure the 44202 module for the appropriate application.

Ensure that power is removed from the equipment shelf. Install the

module in the designated slot.

Action: Apply power to the shelf.

Action: Connect a Transmit Measure Set (TMS) to the XMT LINE

jack on the front panel. Configure the TMS for 600 ohm terminated

measurment. A db meter can be used to make a bridged measure-

ment by connecting to the XMT MON jack.

NOTE:

The XMT MON jack does not open the jack normals and the

1200 hz tone will be transmitted to a connecting circuit,

interrupting data communication.

Action: Place the TEST switch in the on, or up, position.

Result: The RTS and DTR LEDs are lit. A 1200 hz tone is trans-

mitted to the test set.

NOTE:

A failure in step 4 indicates a lack of power or a defective

module.

Action: Adjust the XMT LEVEL potentiometer to reach the engi-

neered data level. Turn clockwise to raise the level; counterclockwise

to lower the level.

NOTE:

If the desired level cannot be reached, remove power from the

shelf and unplug the module. Place the XMT GAIN strap in

the HIGH position to add 20dB of gain. Replace the module,

reconnect power, and adjust the XMT LEVEL pot for the

desired level.

Result: The transmitted tone is set to the desired level.
