Serial communication
Device setting of serial communication need baud rate, parity bit, data bit, stop bit, Parity Bit. ( this parameter must match computer and controller )
Normally, baud rate, parity bit, data bit, stop bit can set by Dip switch or program(Ladder or setting program).
<Table 1> is Device setting example of serial communication.

Description |
com1,9600,0,8,1, |
com1, 9600bps, no parity, 8 data bit, 1 stop bit |
com2,4800,1,7,2, |
com2, 4800bps, odd parity, 7 data bit, 2 stop bit |
com10,19200,2,8,2, |
com10, 19200bps, even parity, 8 data bit, 2 stop bit |
com10,19200,2,8,2,TxRTS |
com10,
19200bps, even parity, 8 data bit, 2 stop bit, use RTS control when Tx ( RS-485/422, .. ) |
com10,19200,2,8,2,TxDTR |
com10, 19200bps,
even parity, 8 data bit, 2 stop bit, use DTR control when Tx ( RS-485/422, .. ) |
com10,19200,2,8,2,TxRTS,RxON,10, |
com10,
19200bps, even parity, 8 data bit, 2 stop bit, use RTS control when Tx ( RS-485/422, .. ), Rx = always Open, RTS on time = 10 milli second |

TCP/IP communication
TCP/IP communication use IP address and Service port.
Device setting example of TCP/IP communication)
TCP/IP, 162.0.9.1, 5000,
when using IP
address = 162.0.9.1,
UDP/IP communication
UDP/IP communication also use IP address and Service port.
Device setting example of TCP/IP communication)
UDP/IP, 162.0.9.2, 2001,
when using IP
address = 162.0.9.2,
MODEM communication
When using a dedicated line(Modem, telephone, etc ), you can use MODEM device.
Setting of MODEM device are same as the serial communication.
<Table 2> is Device setting example of modem communication.
