5.2.1 Basic parameter setting
Basic parameters are for setting communication specification of communication module to decide communication
speed, parity, data bit, stop bit and modem service as required. If modem communication is applied, command for
initializing modem shall be input. (Command for initializing modem may depend on makers, however, mostly set to
‘ATZ’.) [Table 5.2] describes items of basic parameters which are to be set basically. Basic parameters are set
respectively according to channels of RS-232C and RS-422 with setting values saved respectively per
communication channel. [Figure 5.2] shows setting screen of each item in basic parameter screen.
