The ACS235A Extender’s keyboard and mouse interfaces are standard PS/2 type
interfaces, so you can attach just about any standard PS/2 compatible keyboard
and mouse to the Extender. Do not attach serial mice or bus mice to the Extender;
they will not work. You can attach a PC/AT style keyboard with a 5-pin DIN
connector to the Extender by using a keyboard adapter, available separately as
product code FA211.
The ACS236A Extender’s keyboard and mouse interface is a standard Sun type
interface, so you can attach just about any standard Sun compatible keyboard and
mouse to the Extender. The Extender is transparent to Sun keyboard type and
keyboard language.

The ACS235A Extender’s printer interface is an IBM PC style (Centronics
compatible) parallel interface, so you can attach any basic parallel printer (IBM PC
or Centronics type) to the Extender.
CAUTION!
This is a printer interface only. It cannot be used to attach Zip ® drives
and other parallel devices, nor can it be used for parallel file transfer
using utilities such as Laplink
® .
The Extender also doesn’t support the newer IEEE 1284 or Bitronics ®
signaling (and the transmission delay would cause timeout problems for
these protocols anyway), so don’t try to establish bidirectional,
Extended Capabilities Port (ECP), or Enhanced Parallel Port (EPP)
communication with an attached parallel printer.
Lastly, you should be aware that the latest version of the standard
parallel-printer device driver from Hewlett-Packard ® (HP ® ) will not work
with printers attached to a CPU across an Extender link. If you have
problems with your printer driver, contact your printer dealer or HP
support.

The ACS236A Extender’s serial interface is an EIA/TIA RS-232 serial interface,
pinned according to TIA-574 on DB9 connectors just like the serial ports of an
IBM PC compatible computer. The serial port on the Local Module is a DCE and
the serial port on the Remote Module is a DTE. The Extender supports the TD,
RD, RTS, CTS, DSR, and DTR signals. This means that you can attach just about
any serial device to this port that you would directly attach to a PC’s serial port,
including a printer, plotter, scanner, or touchscreen. Keep in mind, though, that
the maximum data rate that the Extender can transmit across the fiber link is
38,400 bps.
