2.3.1 Setup of Satellite I/O Box
The following paragraphs explain how to set up the Satellite I/O Box and Master I/O Box to be
connected to the PC.
Note that the DIP switch settings of the Satellite I/O Box differ depending on the connection with
single Satellite I/O Box or multiple Satellite I/O Boxes.
With single Satellite I/O Box
Make sure that the POWER switch of the I/O Box is set to OFF. Set the DIP switch at the rear
of the unit as follows:
12345
678910
ON OFF OFF OFF ON OFF ON ON ON ON
Set the DIP switches nos. 1 to 5, 9, and 10 as shown above.
DIP switches nos 6, 7, and 8 are used to define the RS-232C baud rate of the I/O Box. It must
be consistent with the baud rate being set on the PC for RS-232C communication.
The above DIP setup example assumes that the RS-232C baud rate is 115200 bps. If modifying
this setup, use the following table as a reference.
Baud Rate 6 7 8
2400 bps OFF OFF OFF
4800 bps ON OFF OFF
9600 bps OFF ON OFF
19200 bps ON ON OFF
38400 bps OFF OFF ON
57600 bps ON OFF ON
115200 bps OFF ON ON
Connect the I/O Box and the PC with a cross-type RS-232C cable.
With Multiple Satellite I/O Boxes
Note that the DIP switch settings of the Satellite I/O Box differ depending on the connection,
ex. Satellite I/O Box directly connected to the PC or Satellite I/O Box connected with other Satellite
I/O Boxes under daisy-chain.
