The ARC-101 is shipped as a DCE. To connect the ARC-101 to a MODEM,
the control port mode must be configured to DTE.
To change the control port mode from DCE to DTE, or vice versa:
1. Turn the unit OFF (disconnect the power cord).
2. Unscrew the twelve box cover screws and remove the box cover. The
12 pin DCE/DTE jumper is located on the left side of the ARC-101
mother board when viewed from the rear panel (see Figure 3-2).
3. To change the configuration to:
•
DTE, place the 12 pin jumper on the upper 12 pins.
•
DCE, place the 12 pin jumper on the lower 12 pins.
4. Replace the box cover and tighten the screws.
