Power and Electrical Interface
LRP76 Long Range Passive Reader/Writer 9
3.5 Serial Connections
The LRP76 can be wired to communicate with the host either through
an RS232 or RS422 interface. Connection to the serial interface is
through the J1 terminal shown in Figure 3-1 on page 7. Connect the
signal ground to terminal 4 on the J1 terminal.
Table 3-2 gives the communication pins for the J1 terminal block.
NOTE:In order to configure the unit for RS422, you must first
establish communications through RS232 and update the
communications parameters.
The signals and electrical loads should conform to the electrical
specifications of EIA Standard for RS232 or RS422. The maximum
cable length specified for RS232 is 50 feet. Use the RS422 interface
for longer communications links. Use high quality shielded cable for
these connections.
