2.5Installation of Satellite I/O Box (multiple units)

Note that the DIP switch settings should be made according to whether the I/O Box is connected directly to the PC or daisy-chained to other I/O Boxes.

The following environment setup example assumes a baud rate of 115.2 Kbps has been set.

Environment setup

1)	Make sure that the POWER switch is set to OFF.
2)	Set the DIP switches of the I/O Box to be connected with the PC as follows.
Table 2.3

Note:

Set No.5 of the DIP switch to ON if the C-OUT terminal is not chained to other I/O Boxes. A terminator should be connected to it.

Connection

1)Connect an AC adaptor to each I/O Box.

2)Connect the I/O Box to the PC with the RS-232C cross-type cable.

3)Connect the C-OUT terminal of the I/O Box, which is connected to the PC, and the C-IN terminal of the other I/O Box with the RS-422 cable.

4)Chain together the remaining I/O Boxes. The I/O Box attached to the terminator must be at the end of the chain.

Start-up

1) Set the POWER switches of all the I/O Boxes to ON.
