2-4. Serial Interface
2-4-1. UART Remote Interface
The PFR-100 uses the IN & OUT ports for UART communication coupled with
RS232 (Part number: GTL-259) or RS485 adapters (Part number: GTL-260).
When using only one unit with RS485, connect the end terminal connector to
Remote-OUT. The end terminal connector is not required in RS232.
The pin outs for the adapters are shown below.

Steps
1. Connect the RS232 serial cable
(GTL-259) or RS485 serial cable
(GTL-260) to the Remote-IN port on the
real panel.
Connect the other end of the cable to the
PC.
When using only one unit with RS485,
connect the end terminal connector to
Remote-OUT.

2. Press the Function key to enter the Normal
configuration settings.
Set the following UART settings:
Function
M1
F-29 = 1 or 2
Interface port:
1 = RS232 or 2 = RS485
F-71 = 0~7
Set the baud rate:
0 = 1200, 1 = 2400, 2 = 4800,
3 = 9600, 4 = 19200, 5 = 38400,
6 = 57600, 7 = 115200
F-72 = 0 or 1
Data bits: 0 = 7 or 1 = 8
