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, see Fig. 2-4.
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 or IDH4. The DOCSIS
specification for downstream power level is +/-15 dBmV. However, for optimal performance, set the level as close to
0 dBmV as possible.
