3.1Setting the Transmission Speed (Baud Rate) and Transmission Format

When using the Computer Communication Unit to carry out serial communication with an external device, the transmission speed (baud rate) and transmission format must be set ahead of time to match those of the external device that will be serving as the partner station.

With the FP2 Computer Communication Unit, the transmission format setting switches (DIP switches) can be used to change only the transmission speed (baud rate) and character bit to match those of the external device.

If the transmission speed (baud rate) of 19.2 kbit/s or more is necessary, use the Multi Communication Unit.

3.1.1Transmission Format Setting Using Switch

The transmission format setting switches can be used to change the transmission speed (baud rate) and character bit settings for the COM.1 and COM.2 ports. The values set with these switches become effective when the power supply is turned on.

Transmission speed (Baud rate): on−off: 19,200 bits/s off−on: 9,600 bits/s

Character bit: on: 8−bit on−on: 4,800 bits/s off: 7−bit

For COM. 1 port

For COM. 2 port
