MPRX
TransCore Proprietary 8–15
You can configure the MPRX to generate input status change reports, which are transmitted
like tag IDs. The host can then respond based on the true/false (closed/open) status of the
sense inputs. Refer to the section
“Reports” on page 8–12 “.
The following procedures describe how to set sense inputs using the terminal emulation
software. Refer to command
“694N Select Input Inversion Option” on page 7–32 for more
information.
To set sense inputs
1. Ensure that the host device is in command mode.
2. Enter command #6940 to disable input inversion (factory default) or command
3. #6941 to enable input inversion, and press ENTER.
Sense Output Device
The
sense output is dedicated for testing and set up of the reader. It is defined as the
TAG_LOCK signal and indicates that a valid tag is in the read field.
This sense output is a dry contact that provides a normally open and normally closed
sense output. The relay contacts are rated at 42.2V AC peak (30 Vrms) or 60V DC at 1
A maximum. If controlling an external gate or device requiring high current, an isolation
transformer is required.
Serial Port Communications
The MPRX supports one RS–232 communications port. For the RS–232 communications
specification, the MPRX maintains the following three sets of parameters that affect serial
port communications:
• Port configuration parameters (baud rate, data bits, stop bits, parity)
• Communications protocols (basic, error correcting)
• Flow control scheme (none, software)
The default serial port configuration for each of these three parameters is as follows:
• 9600 baud, 8 data bits, 1 stop bit, no parity
• Basic communications protocol
• Software flow control (XON/XOFF)
You can change these parameters in data mode and command mode operation by
issuing commands with the host device. Use the following procedures to set serial port
communications parameters using the terminal emulation program.
Port Configuration Parameters
Use this procedure to set port configuration parameters using the terminal emulation
program. Refer to sections
“100N Select Baud Rate” on page 7–6, “100N Select Baud
Rate” on page 7–6 through “102N Select Parity” on page 7–6
To set baud rate
1. Ensure that the host device is in command mode.
