Interface RS-485 1 channel
Transmission distance Max. 1,200 m 3,937.008 ft
Communication configuration 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.
