Printer Interfaces
The following printer interfaces are not directly supported on an NonStop S-series
server:
•
RS-232
•
Current loop
•
Centronics
•
Dataproducts Long Line Parallel (DPLL)
However, each of these printer interfaces can be indirectly supported and connected
by using converters and remote access servers.
RS-232 Serial Interface:
An RS-232 serial interface works without conversion on an AWAN access server
(3883/3884/3885) even though current loop is recommended. An RS-232 serial
interface also works with the AWAN 3886-family of terminal servers.
Current-loop Interface Printer:
A current-loop printer can be connected by either using a SWAN concentrator or an
AWAN 3886 server and converting the printer’s RS-232 output to current loop by using
an HP-designed RS-232 to current-loop converter (T3886-CL).
AWAN servers also support current-loop through a separately designed current-loop
module. However, these terminal servers are subject to controlled availability.
See Current Loop.
Centronics Parallel Interface:
A Centronic parallel interface on a printer can use a Centronics to a TCP/IP Ethernet
LAN converter to connect directly to the LAN.
DPLL Interface:
A printer that has a DPLL interface can be connected to a NonStop S-Series server if
the DPLL interface is replaced with either a serial, Centronics, or a TCP/IP Ethernet
LAN interface on the printer.
