The VR2C supports several ASCII RTM Mode commands.
3.2.5.3.1 RTM232
The RTM232 command starts the VR2C in real-time mode and causes the receiver to transmit the real-time
output on the RS232 communication lines.
Command:
*450088.0#25,RTM232\r
Response:
*450088.0#25[0009],OK,#9A\r\n
3.2.5.3.2 RTM485
The RTM485 command starts the VR2C in real-time mode and causes the receiver to transmit the real-time
output on the RS485 communication lines.
Command:
*450088.0#25,RTM485\r
Response:
*450088.0#25[0009],OK,#9A\r\n
3.2.5.3.3 RTMNOW
The RTMNOW command starts the VR2C in real-time mode and causes the receiver to transmit the real-
time output on the communication lines on which the RTMNOW command is received (RS232 or RS485).
It forces the RTM output to the port it was received on.
Command:
*450088.0#25,RTMNOW\r
Response:
*450088.0#25[0009],OK,#9A\r\n
3.2.5.3.4 RTMPROFILE=x
The RTMPROFILE=x command allows the user to control the timing of the VR2C’s RTM output by
selecting one of three possible RTM profiles (Profile 0, Profile 1 and Profile 2). These profiles are described
in detail below.
RTM Profile 0 (Immediate Output)
This profile outputs tag detection records as soon as they occur. Additionally, a VR2C status
line is outputted periodically.
The default status line interval is 60 seconds, but it can be user configured to any value between
1 and 65535 seconds by adding
SI=x
to the command as shown in the example below (which
specifies a status line interval of 120 seconds). Specifying a status line interval of ‘0’ will
disable the status line output altogether for RTM Profile 0.
Command:
*450088.0#25,RTMPROFILE=0,SI=120\r
Response:
*450088.0#25[0009],OK,#9A\r\n
RTM Profile 0 will not commence until an RTMNOW, RTM232 or RTM485 command has
been issued.
