User's Guide

1. Each address of modules should be different and apply power after setting address without applying power to master or, it may cause communicational error.
2. Do not connect the expansion module after applying power or, it cannot recognize the expansion module.
3. Communication speed is set in master and OFF the power and apply power again after changing communication speed in master to change the speed during the operation.
4. Use the rated cable, tap and terminating resistance in module or, it may cause a communicational error.
5. Use the rated communication cable and examine the disconnection or short circuit before the installation.
6. Use terminating resistance on both ends of the main line.
7. Do not use this unit in place with too much dust or serious corrosion problem.

* It may cause malfunction if above instructions are not followed.
