CVX-1300 Serial data and RS485
The CVX-1300 can support both RS-232 and RS-485 signals for transmitting and receiving
serial data. For most converters utilizing serial data, both interfaces are always active and may
be used by making the appropriate connections to the converter. Either the RS-232 or RS-485
interface may be used, but a loss of data will occur if both interfaces have active data at the
same time.
Examples:
The CVT-2232 function will provide a serial input and convert to a Wiegand output.
Serial data can be read from either the RS-232 or RS-485 interface. The baud rate will be
determined by the DIP switch setting.
The CVT-9110 function will provide a Wiegand input and a serial output. Serial data will be
output on the RS-232 and RS-485 interface.
NOTE: Some of the CVX-1300 converters may not support both RS-232 and RS-485
interfaces. Converters that do not support both interfaces will be noted in the specific converter
specification.
