1-2  Selections and Programs for the Communication
The following preparations are necessary for RS1/2/4 to communicate between a CPU module of MICREX-SX series and
external devices.
  Initializing parameters for a RS-232C port and a 
  RS-485 port.
 (Transmission speed, data length, parity bit, stop 
  bits etc.,)
  Application software for the communication.
FA packages are optionally provided 
for each external device.
External device
<RS1/2/4 side>
Selection switch of the module is used.
  RS-485 station No. selection switch (0 to F)
  If RS-485 port is not used, the selection is not 
  necessary.
  Mode selection switch
  Device selection of RS-232C port and RS-485 
  port, Data conversion
  RS-485 terminating resistor ON/OFF switch
  ON/OFF of terminating resistor is selected.
  If RS-485 port is not used, this switch is ignored.
<External device side>
  Transmission speed, data length, parity bit, stop bits etc.
  Application software for the communication.
