4.7LTC 4671 Series Modules for System4 / Allegiant Keyboard Transmission

1.The supplied 120 ohm resistor must be installed across the external data connections when these fiber optic modules are used with certain controller devices. Follow the guidelines below, however, because of differences between the hardware of new and old controller units, these cases are not absolute. If a configuration does not work when first connected without using a termination resistor, try adding the termination resistor across the data connections of the fiber optic module located at the controller site.

A termination resistor is typically required when a module is connected to the following controller devices:

Allegiant LTC 8100 Series main CPU bays

Allegiant LTC 8200 Series main CPU bays

Allegiant LTC 8300 Series main CPU bays

Allegiant LTC 8900 Series main CPU bays

LTC 8714 Series Allegiant Keyboard Expander accessory units sold prior to 2002

LTC 2604 Series Multiplexer Keyboard Expander

A termination resistor is typically NOT required when a module is connected to the following controller devices:

Allegiant LTC 8500 Series main CPU bays

Allegiant LTC 8600 Series main CPU bays

Allegiant LTC 8800 Series main CPU bays

LTC 8714 Series Allegiant Keyboard Expander accessory units sold during or after 2002

If the supplied resistor is damaged or lost, any locally obtained conventional 1/4 watt carbon resistor between 120 ohm and 390 ohm should suffice.

2.The POWER LED will light when AC power is applied to the unit.

3.The DATA XTMR LED will flash as the external data received by the unit is being optically transmitted.

4.The DATA REC LED will flash as optical data is being received by the unit.
