Table Q – MIC-USB485CVTR Connection Table and Diagram

The MIC-USB485CVTR is a USB to RS485 signal converter that allows PCs without a serial port to connect directly to the MIC400 series camera via the telemetry connection (HD4) in the power supply, the MIC-USB485CVTR can also be used to connect a PC to any other RS485 device.

The MIC-USB485CVTR has been designed to work with all functions in Universal Camset and to be backwards compatible with legacy version of Camset although full compatibility is not guaranteed.

The MIC-USB485CVTR should be connected to the telemetry header (HD4) of the MIC400 power supply with Standard Twisted Pair cable such as Belden 8760.

The table overleaf shows how the screw terminal connections on the MIC- USB485CVTR connect to the MIC power supply depending upon the protocol and selected communication mode you may only need a 2 wire configuration.

CAUTION: Should be taken to avoid earth loops when connecting 0v from the converter to GND terminal in the MIC power supply
