15 Interfaces
Overview
The printer interface is the point where the data line from the host c omputer
plugs into the printer. The interface processes all communications signa ls and
data to and from the host computer. It consists of a printed cir cuit board
assembly (PCBA) and a connector for the data cable from the host computer.
Communication signals and data may be sent over Ethernet, paral lel, or serial
lines.
When data is sent through multiple interfaces, the Autopor t Switching feature
forces the printer to automatically switch between the serial and p arallel port
and between the Ethernet adapter and the serial port when NIC is ins talled.
This chapter describes the following interfaces:
Centronics
Bi-Tronics
RS-232 serial
RS-422 serial
Note To determine which interface is installed on your printer, refer to Table 1 on
page 19. If you require a parallel interface and it is not inst alled, contact
your authorized Printronix representative.
