31 WIRING Actual gage connections to the terminal board will vary depending on the instrument type and cable used. Note the following tables to get the general idea.
32 Figure 10 depicts the terminal board to which gage connections are made. If the terminal board is equipped with manual switches, connectors J1 and J2 will have ribbon cables that are connected to the switch boards. Terminal Blocks T1/2 to T31/32 are for the gage connections.
33 TROUBLESHOOTING Below are some commonly experienced problems along with possible remedial action. Contact the factory if any problem remains unresolved or additional help is required. A particular channel on the multiplexer appears to be malfunctioning. • Check sensor connections on the terminal board. Clean if corrosion exists. • Try moving the sensor wired to the suspect channel to another channel to verify the malfunctioning of the channel (as opposed to the sensor). No channels are working.

37 DAISYCHAIN OPERATION Up to (8) 8032’s may be ”daisychained” together using a common RESET and CLOCK control line. This may be advantageous in situations where either there are not enough control ports available on the Micro-800/MICRO-1000 datalogger for the number of multiplexers desired, or to reduce the number of cables required to implement a large multi-channel system.

39 MAXIMUM 8032-5 (TAN CABLE) CABLE LENGTHS The 8032 Multiplexer is a low power device, that when combined with a Micro-800 or Micro1000 Datalogger can be physically located at a considerable distance from that Datalogger. Still, there are limits to the maximum distance – mostly due to the voltage dropped by the 8032-5 MUX cable over its length.
