MPRX
TransCore Proprietary 4–11
Caution
To avoid damage to the MPRX, connect the antenna(s) before applying power
to the reader
Mounting the Antenna Rail-Side
Position the antenna as close as possible to the MPRX. Long cable runs increase system
sensitivity to noise. Refer to
Table 2 – 5 on page 2–13 for maximum RF cable lengths.
After mounting the antenna, you must connect it to the MPRX. Follow the procedures
described previously in the section
“Connecting the Antenna” on page 4–6 .
Note: Adjust the antenna(s) to provide the most direct line of sight to the tags.
Connecting the Power Supply
After mounting the MPRX, connect the reader to a dedicated 12 to 24VDC or 24 to
110VDC power supply. If the MPRX is connected directly to a TRU, all power supply
connections are made through the MPRX-to-TRU cable assembly.
Caution
To avoid damage to the MPRX, connect the MPRX to ground before powering up the
reader or connecting the antenna(s).
Connect the antenna(s) before applying power to the reader.
Interface Selection Switch
The MPRX incorporates a communications interface selection switch, which allows on-
the-fly changes to the communications mode. This switch allows selecting the reader’s
receive communications interface. All communications interfaces are configured
for simultaneous transmit, but only the interface selected by the switch is active for
commands transmitted into the reader.
