•The network address No. is set to 1 at the shipment from the factory.

The following two methods are used for setup.

2. Setup by the switch on the adapter P.C. board

Requirement in Service Time

When the remote controller is not found, or when you do not want to change the setup of network address No. on the remote controller, set up the address No. by using the setup switch SW01 (Network address No. setup switch) on the adapter P.C. board.

When using this product as the service part for change of the adapter P.C. board, be sure to set the setup switch SW01 (Network address No. setup switch) on the adapter P.C. board so that it is same as one before change.

<Procedure>

1 Turn off the power supply.

2 Set [7] of the address No. setup switch SW01 to ON side.

Address No. setup on the remote controller is invalid.

Accordingly, the setup of the address No. from the remote controller is invalidated. (Fig. 2)

3 The network address No. is set up by com- bining ON/OFF of the address No. setup switch, from SW01 [6] to [1].

For the relation between ON/OFF combination and the address No., see (Table 2).

A case when the address No. is set to 16 is
