About the CVCC
The CVCC (Current to Voltage Communication Converter) is a passive communication link
used to interface Milltronics equipment using proprietary 20 mA bipolar communication
format with RS-232C or RS-422 communication of a customer’s computer.
Transmissions that enter the CVCC will cause the front panel LED’s to flash, providing a
visual indication that communication through the CVCC is being achieved. The messages
are passed through without interpretation or modification of the message. The CVCC
simply converts the signal level from RS-232C/RS-422 to 20 mA current loop or vice versa.
Installation
1. Take off the top cover by removing the four upper screws.
2. Connect data link from the Milltronics equipment. Refer to Interconnection.
3. Connect data link from the customer’s computer. Refer to Interconnection.
4. Check power input jumpers for standard 115/230 Vac or special 100/200 Vac
operation. Refer to Interconnection or board silkscreen.
5. Connect power. Refer to Interconnection or board silkscreen.
6. Flip power switch to ON.
7. Replace cover and secure.
