Interface RS-232C 1 channel and RS-485 1 channel
Transmission distance [RS-232C] Max.15 m 49.213 ft
[RS-485] Max. 1,200 m 3,937.008 ft
Communication configuration [RS-232C] 1 : 1 communication
[RS-485] 1 : N communication
Communication speed 1,200(Note), 2,400(Note), 4,800, 9,600, 19,200, 38,400, 57,600, 115,200, 230,400 bits/sec.
(Note): System register no. 415 cannot be used to set the baud rate to 1,200 bps. To set the baud rate to 1,200 bps, use the SYS1 instruction. If the baud rate of any of the COM ports is 2,400 bps or lower, F-ROM access will slow down.
Example) F12(ICRD) instruction, P13(ICWT) instruction, etc.
