Power and Electrical Interface
8 LRP75 Long Range Passive Reader/Writer
3.2.2 Connections
Connection to DC power is through pins 1 and 2 of the internal
terminal block J1.
3.3 Serial Communications
The LRP75 offers either RS232 or RS422 communications. The
RS422 option provides the superior reliability over longer distances or
in noisy environments. Communication parameters, such as baud
rate, are set by the configuration program.
CAUTION:Do not bundle communications wiring with high current
power lines. This will cause communications errors.
3.4 RS232/RS422 Interface
The LRP75 is set to automatically enter run mode seven seconds
after power-on the device. This allows you to enter the configuration
program by entering a <control D> after power-on. If no commands
are received by the reader/writer during the seven seconds, the
LRP75 enter run mode with existing operating parameters. For more
information on the Configuration Menu refer to Chapter 4.
To communicate with the device via RS232, set the serial
communications parameters of the host as follows:
Baud rate 9600
Parity none
Data bits 8
Stop bit 1
NOTE:The LRP75 automatically resets to 9600, N, 8,1 for seven
seconds whenever the power is cycled, after which it will apply
the setting made in the configuration menu.
