3.2.5.3.6 RTMOFF
The RTMOFF command disables RTM output from the VR2C.
Command:
*450088.0#25,RTMOFF\r
Response:
*450088.0#25[0009],OK,#9A\r\n
3.2.5.3.7 RTMAUTOERASE=x
The RTMAUTOERASE=x command is used to force the VR2C to automatically erase detection log data in
order to ensure that the detection log never fills up (which would result in detections not being stored).
When the threshold is set to a non-zero value, the receiver will automatically keep the desired portion of the
detection log free after each RTM output (erasing data as required to do so). Keep in mind that data erased
by the auto erase function is not recoverable and is assumed to have been captured by a device monitoring
the RTM output.
Note: To enable auto erase, the RTMAUTOERASE=x command must be sent
after
the RTMPROFILE=x
command (because the RTMPROFILE command sets the auto erase threshold to 0).
Command:
*450088.0#25,RTMAUTOERASE=10\r
Response:
*450088.0#25[0009],OK,#9A\r\n
The above command example causes the VR2C to keep 10% of the detection log free.
3.2.5.4
Detection Log Manual Retrieval (Advanced User Feature)
The VR2C supports several ASCII commands that allow the host to manually retrieve detection log entries
in ASCII format.
Note: It is
strongly
recommended that the host not use these manual log retrieval commands while in real-
time mode as these commands manipulate the VR2Cs internal detection log read pointers.
3.2.5.4.1 READBEG
The READBEG command sets the VR2C’s internal detection log read pointer to the first tag detection
record in memory (The first tag detection record since the last erase occurred).
Command:
*450088.0#25,READBEG\r
Response:
*450088.0#25[0009],OK,#9A\r\n
