iguration
When TCP/IP, WiFi or GPRS/3G connections are unavailable, a serial connection is the
preferred communication between the terminal and PC. RS 232 is a one-to-one connec-
tion between a device and a PC. The RS485 supports the network wiring by using the
RS485 cable to associate multiple devices to a PC.
A data converter must be installed at the PC to switch the RS 485 data signal to a RS 232
signal that can then be processed by the PC.
To setup either RS 232 or RS 485:
Step 1: Menu > COMM. Settings > Serial Comm > Select RS232 or RS485 > OK to
turn on.
Step 2: Configure the settings in the page as explained below:
• Baudrate: This is the communication speed for the serial connection. RS 232 supports
up to 115200 bps, while the RS485 supports up to 9600 bps to ensure no loss of data
is incurred.
