STEP 1: Connect 24 Vdc to the POWER input (terminals or jack) if this module is not being powered through the twisted pair cable from
another module, or if this module is located an excessive distance from the next powered module on the cable. Note: The front-panel power
LED will be illuminated if this module is powered. If this module is powering other modules through the cable and if there is a wiring short,
the short must be cleared then power must be turned off to this module for 10 seconds to reset the internal protection circuit.
STEP 2: Set the PAIR selector so the module is receiving signal from the desired pair A, B or C of the Format-A cable.
STEP 3: Connect the UNBAL OUT jack to a -10 dBV equipment input, and/or connect the BAL OUT terminals to a +4 dBu equipment input.
STEP 4: Connect the INPUT twisted pair cable coming from Format-A senders or distributors.
STEP 5: Connect the LOOP OUT twisted pair cable feeding additional Format-A receiver(s), if any, and mount the module.
