1. Connect Battery Sense Wire Harness to the A/B, C/D connection points (14) on the
transponder. The connection (14) is not required for individual battery monitoring if
the Smart AlphaGuard option is deployed. For XM3 units with the Smart AlphaGuard
option, connect the Battery Harness (5) to the AlphaGuard connection located on the
left side of the XM3 Power Supply.
2. Connect Tamper Switch Wire Harness to the TPR Connector (18).
3. Connect the RF drop (15) and make front panel connections as shown below for
the DSM3. The DOCSIS specification for downstream power level is +/-15 dBmV.
However, for optimal performance, set the level as close to 0 dBmV as possible.
