Enabling/Disabling Receiver Serial Transceivers
To conserve power, the VR2C disables its serial RS232/RS485 transceivers after either 30 seconds of
inactivity on the communication lines or issuance of the ASCII
QUIT
command. Once disabled, the serial
transceivers need to be enabled again prior to sending any additional serial commands to the VR2C. The
transceivers can be enabled by sending the receiver any ASCII character followed by a short delay of at least
100ms.
