CAUTION

„Always unplug the AC adapter from the printer before connecting the printer to a Powered USB interface. Failure to do so may damage the host PC. For information about installing a Powered USB interface, contact your Citizen Systems dealer.

„Check the orientation of the Powered USB cable connector before connecting it. Insert it straight in so that the pins do not bend. Push it in until it clicks.

„When disconnecting the cable, always hold the connector.

„Be careful not to insert the USB interface cable into the cash drawer kick-out connector.

„To connect more than one printer to a single computer via a USB interface you must change the serial number of the USB interface.

Use a serial interface cable with the connection layout shown below.
