After repairs or diagnostics, it may be necessary to reinstall an iSIC data logger’s circuit board.
1. Mount the PCB to the mounting plate using (4) M3 x 16 screws and (4) M3 lock washers.
2. Turn the mounting plate over, place an M3 lockwasher and an M3 hex nut on the one screw in the corner shown.
Do not overtighten the screws.
3. Plug the MTA connector from the battery cable into the PCB (SLABAT position).
Make sure the fastons from the battery cable are connected to the top fuse holder. The fastons must be completely latched onto the fuse holder plates.
4. Plug the MTA connector from the MS2 Cable into the PCB (CHARGE position).
5. Connect the fastons from the MS2 cable to the bottom fuse holder.
6. Insert the JST connector from the MS8 cable into the socket on the PCB marked “MS8”.
7. Insert the JST connector from the MS3 cable, if there is one, into the socket on the PCB marked “P4-P6”. This connector is used for allowing direct connection from a PC serial cable to the MS3 port on some iSIC data logger enclosures. If cellular, radio or satellite telemetry is being used, this cable likely won’t be included. Data will be sent by the chosen telemetry method and the iSIC data logger will usually not have an MS3 port.
If a cellular modem is attached to the board, make sure that its modem power cable is connected to the SW12VA pin. The RF cable should be connected to the RF connector on the modem and the modem serial cable should connect to the front of the iSIC data logger.
If a radio is attached to the board, make sure that the RF cable is connected to its RF connection. Note that the radio RF connection should be hand-tightened plus 1/4 turn.
8. Secure the mounting plate to the 2” standoffs using (4) ¼-20 x 3/8” screws and ¼-20 lock washers. Use a #3 Phillips head screwdriver.
9. Insert terminal strips.
10. Re-connect DB9 jack screws.
11. Re-wire as needed according to appropriate sensor interface guides
