switched Video Out cable to BNC socket CN3. This second cable provides control for video
from both the optical camera and the thermal camera; users can switch between the two
cameras.
25. Feed telemetry cable through the bottom-right M12 cable gland (item 4 in the figure “MIC
PSU Enclosure, with cable glands identified”).
26. Connect head-end RS-485 control to terminal block HD5, as indicated in the table below:
PCB Marking
(non-IR PCBs)
Telemetry Signal Name Connection Description / Function Pin Number
RxB Rx + RS485+ to camera 1
RxA Rx - RS485- to camera 2
0V Ground 0V from control room 3
TxA Tx - RS485- to control room 4
TxB Tx + RS485+ to control room 5
Note: The terminal block is positioned with the screw terminals on the left, next to the fuses.
Pins are numbered from top to bottom in that orientation. Non-IR PSU PCBs are marked.
27. If connecting to additional add-on cards (for example, a card for 8-input alarms (MIC-
ALM), and/or a Biphase card (MIC-BP4)), remove the second blanking plug that covers one of
the holes for an M12 cable gland (item 3 in the figure “MIC PSU Enclosure, with cable glands
identified”). Attach the supplied M12 gland. Make the appropriate connections to plug-in
terminal CN2.
Notice!
For installation of the MIC 8-input Alarm Card (MIC-ALM) or Biphase converters (MIC-BP3 or
MIC-BP4), please refer to their respective manuals.
4 For physical alarm connections on MIC IR power supplies, connect alarm input cables to
terminal block HD2, as indicated in the table below:
