PRV-LX1 RS-422A Protocol
The controller must ensure that no more than a 10 msec lapse occurs between bytes in a command
block.
The controller must immediately stop sending data when it receives a NAK + Error Data message. The
unit must wait at least 10 msec before resending the command.
The controller should wait at least 10msec to receive a response from the PRV-LX1. The unit should not
send another command during this time.
When the controller does not receive a response from the PRV-LX1 within the 10 msec timeout, it
assumes that communication has ceased and sends the command again.
• Error descriptions are listed in this manual under the section entitle Command Formats
If the PRV-LX1 detects a communication error, it sends a NAK and an error code to the controller.
