4.2.9. Serial Port Parameters
To connect the serial device to the Super Series serial port, the serial port parameters of the Super
Series should match exactly to that of the serial device attached. The serial port parameters are
required to match this serial communication. The parameters required for the serial communication
are: UART type, baud rate, data bits, parity, stop bits, flow control DTR/DSR behavior and inter-
character timeout.
UART type
First of all, the Super Series and the serial device must agree on the serial communication type, which
is one of RS232, RS422, RS485 echo mode or RS485 non-echo mode. The Super Series serial port is
configured for RS232 communication as a factory default, but it can also be configured for RS422 and
RS485 communication. To change the serial communication type, set up the mode in the Type menu.
The Super Series supports two types of RS485 communication – echo mode and non-echo mode,
which are both two-wire mode. In RS485 echo mode, all data received from the serial port are
automatically sent back to the serial port while there is no action of sending-back in non-echo mode.
For more information about pin out of serial port and wiring diagram, please refer to Appendix 1.
Connections section.
Baud rate
The valid baud rate for the Super Series is as follows:
75, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400
The factory default setting is 9600.
