Entry MPRX Response Notes
#01 <CR> #Done <CR/LF> Switches the MPRX to command
mode
#505 <CR> #Model E4 Series Ver
X.XX SN97001P <CR/LF> Reports the software version
and serial number
#00 <CR> #Done <CR/LF> Returns the MPRX to data mode
3. If a successful sign-on message is not returned, check connections and
communications factors and correct any errors.
To check connections and communications factors
1. Confirm that the MPRX has power.
2. Verify the connections between the PC and the MPRX.
3. Verify the receive (Rx) and transmit (Tx) connections.
4. If using handshaking, verify the request to send (RTS) and clear to send (CTS)
connections.
5. Verify the COM port settings for the MPRX following the instructions in “Serial Port
Communications” on page 8–15 .
Repeat the procedures in “Verifying Communications” on page 8–6.
If you still cannot verify the MPRX and PC communications, contact TransCore Technical
Support.
Verifying Tag Read Capability
After verifying communications between the MPRX and the PC, verify the capability to read
tags. The test tag should match the tag type and protocol of the tags that your system will
be reading.
The polarization of the test tag must be aligned in the same direction as the antenna.
Figure 8 – 6 shows horizontally polarized antenna and tag.
Note: Matching the tag and antenna polarization is critical to obtain optimal system
performance.
