Connecting the Printer

The printer must establish communications with a host terminal which sends the data to be printed. Communications occur in three basic ways:

•By a cable between the printer and its host terminal using either RS232C or USB protocols.

•By means of a Bluetooth short-range radio frequency link.

•By means of a wireless LAN (Local Area Network) per 802.11b specifications.

While the RW 420 can be equipped with both a Bluetooth radio and a 802.11b radio they cannot be operated concurrently.

CAUTION. The power should be turned off before connecting or disconnecting the communications cable.

All RW 420 printers can communicate by cable; the specific cable supplied with your printer will vary with the host termi- nal. The 10- pin modular connector on your communications cable plugs into the serial (RS232C) communications port on the side of the printer. Plug the connector into the RS232C port and ensure the locking device has clicked into position. Then press the Locking Plug into the opening around the con- nector, aligning its locking features with the cutouts on the RW 420 case. Turn the Locking Plug clockwise one-quarter turn to secure it in place.

The other end of the cable must be plugged into the host
