Table 1:
BDL168 44-Pin Connector Pin Out Configuration
Notes:
1) All connector pins are paired top (component side) and bottom (sol-
der side) except 11/M and 12/N. For 6 Amp current rating with 3 Amp
connector pins, track/zone wires
must
be connected to both pin pairs:
e.g. Zone A = pins 1 & A (See Figure 4).
2) Letters G, I, O & Q are not used as pin designations on the connector.
3) Power connections should be made to a power supply dedicated to
BDL168 use only. Multiple BDL168 units can be supplied by a single shared
supply as long as you provide at least 100mA for each BDL168.
4) The Ground connection, pin 11, must be made to the booster for correct
BDL168 operation.

Confirm that the 44-pin connector is plugged in to the
BDL168 in the correct orientation to avoid damage to
the BDL168 when power is applied. See Figures 1 or 2
for proper connector orientation.
