Appendix A - Communication Device

The Communication Device is an accessory product that can be used to calibrate and set up RDO probes.

Install and Open the Software

The Comm Kit Software must be installed on a computer before you connect to the probe.

Connect the Probe to the Communication Device

The Communication Device connects a stripped-and-tinned probe to a computer via USB connection.

1. Disconnect the instrument from the PLC.

2. The communication device includes an electrical connection diagram label. To attach the instrument to the

communication device, depress a lever and insert the appropriate wire in the location specified by the diagram.

3. Attach the USB connector to a USB port on the computer. Follow the directions provided in the Communication

Device Kit to set up the probe.
