TROY Group MAN-EXT2000 - Manual (Page 33)

Installation 2-19
If you are using the serial port and the test page does not
print, verify that the baud rate, parity, and character size
match on the print server and the printer. If you have an
XConnect II, make sure that switch 4 is in the ON position.
If you have an XConnect 100 and you are using the second
serial port, make sure that you have disabled console
operation via the
SET PORT S2 CONSOLE DISABLED
command.
If none of the above suggestions work, contact TROY XCD
Technical Support (949-399-0820; http://www.troyxcd.com; e-

Adjusting the Parallel Port Settings for Specific
Printers (Recommended)
The parallel port on all new TROY XCD print server models
is set by default to automatically configure itself to work
with the printer's parallel port However, it may sometimes
be necessary to adjust the print server's port settings to work
with specific printers by using the print server console or
WebXAdmin. This is particularly true with older printers.
The particular settings include:
1. pACK handshake. Older non-1284 printers require this
hardware handshake and may not operate with the newer
1284 handshake. Use the console command
SET PORT
P1 ACKH ENABLED to enable the pACK handshake.
2. DMA (Direct Memory Access). The XConnect II and
XConnect 100 use DMA for maximum performance.
However, some printers cannot handle the high data
rates. For such printers, use the console command SET
PORT P1 DMA DISABLED. Alternatively, you may
disable DMA using the Configure Port option in the
WebXAdmin menu,
