1: When resetting the system, press and hold the RESET switch for a second or more. If the pressing
time is too short, the system may not be reset normally. If the system is not reset normally, try reset
operation again.
POINT
1) There can be no duplication of station numbers in the same network.
2) Setting can be done regardless of station sequence. However, if a number is to
be left empty, sting a reserved number.
3) Set the mode setting switches in the same position on all network modules.
