n Setting the transmission rate for RS-232C serial interface ports
Access: [F6: Set]—[F5: Set Com.]—[F2 Serial IF]
Select each of the COM3 and COM4 and then press [F5 Change.] to the
transmission rate, parity (None, Odd or Even) and other values.
NOTE: The default transmission speed for the RS-232C extension board is 19,200
bps. The maximum transmission speed is 38,400 bps.
If the transmission speed is set to 38,400 bps, however, a communications failure
may occur frequently. Even at 19,200 bps, a communications failure may also occur
due to electric noises or other interference.
In programming, therefore, you may need to use the
com_state
command for setting
retry capabilities as shown in the coding sample below.
