DB-9 Breakout Cable (Straight Thru Cable) – 3 Channels
The optional DB-9 Breakout cable will convert your 9-PIN RS-232 device to 3 separate channels of 3-PIN RS-232
serial data as illustrated below. The break-out cable is wired as a straight through cable, if the device is in DTE
mode, all 3 connectors will be DTE type interfaces. Likewise, if the Device is in DCE mode, all 3 connectors will be
DCE type interfaces. If you are connecting DCE to DCE or DTE to DTE a crossover cable will need to be used on
those connections.

Connect Power
The system has redundant power terminals that accommodates a backup power supply in the event of an outage.
Follow these steps when attaching wires to power terminals located on the top of the module.
•
Check that DC power source voltage matches the accepted
voltage range of the device to avoid damaging the unit.
•
Disconnect power from the DC power source prior to
connecting to the Fiber Link.
•
Connect the DC power cables to the terminal pairs
labeled PWR 1 or PWR 2. The system is NOT polarity sensitive.
•
Energize the power source. The POWER LED will be ON
indicating that the system has power.
