8-4. Jumper Setting

The serial interface is set to the RS-232C mode upon shipment from the factory. When using in the 20mA current loop mode, it is necessary to set the jumpers. The jumpers built into the Control Board allow for setting of functions shown in the table. However, the Bottom Cover must be removed to perform this setting. For setting the Jumper, disconnect the power source beforehand.
