SATO LM408/412E Interface Selection, RS232C HIGH-SPEED Serial Interface, Interface Specifications

Unit 3: Installation

INTERFACE SELECTION

This unit presents the printer interface types and their specifications. These specifications include detailed information to assist in the selection of the most appropriate method for the printer to interface with the host. The five acceptable interface methods are:

•RS232C High-Speed Serial

•IEEE1284 Parallel

•Universal Serial Bus (USB)

•Local Area network (LAN) Ethernet

•802.11G Wireless

Following the selection of the desired interface, proceed to the next unit for instructions on how to Configure the printer for that interface type.

WARNING: NEVER CONNECT OR DISCONNECT INTERFACE CABLES (OR USE

A SWITCH BOX) WITH POWER APPLIED TO EITHER THE HOST OR THE

PRINTER. THIS MAY CAUSE DAMAGE TO THE INTERFACE CIRCUITRY IN THE

PRINTER/HOST AND IS NOT COVERED BY WARRANTY.

NOTE: Some hosts monitor the Request-To-Send (RTS) signal (pin 4 of 25) to determine if the printer is ready to receive data. Since the printer does not generate this signal, the RTS line must be held true (high) in order to allow communication. This can be performed by connecting the RTS pin to the Clear-To-Send (CTS) signal (pin 5 of 25).

NOTE: If assistance is required on the physical installation of the interface, refer to the

Accessories Installation unit for guidance.

RS232C HIGH-SPEED SERIAL INTERFACE

This High Speed Serial Interface is a Plug-In Interface Module that can be installed in the printer by the user.
