[5] Expansion communication setting
Expansion communication setting is supported from software ver. 2.3.
Several communication parameters (length of data, type of parity, number of stop bits, checksum available / not
available, and so on) can be set from CPU module by using expansion communication setting.
« Note »
･ When expansion communication setting using, setting of DIP Sw in EH-SIO is invalid. (excepts DIP Sw2
bit8 and DIP Sw4.)
・If using expansion communication setting, please set sending data in initial setting as follows.
[1] Number of send data (bytes) … 8 / H0008
[3] Specification of Transmission procedure, Usage of station number
… HFExx (Standard procedure, xx : station number) or
HFFxx (Simple procedure, xx : station number)
