Unit 3: Installation
CL408-412e Supplemental Manual
3-8 PN: 9001159A
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
• 802.11b 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.
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.
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.
