SERVSWITCH™ BRAND CAT5 KVM EXTENDER STANDALONE REMOTES
Appendix C:
Setting Your KVM/Serial Extender
System to 1200 bps
NOTE
This procedure is intended primarily to meet the needs of customers
with industrial trackballs and other 1200-bps serial peripherals whose
output can’t be converted to PS/2 mouse format. We do not recommend
using this procedure to connect standard serial mice; use a PS/2 mouse
with a PS/2 to serial mouse converter such as our product code AC244A
instead.
We suggest that you avoid making this change unless you really
need to, because (a) your Local shouldn’t be opened any more than
necessary and (b) if the Local is a Hub, it can be very easy to lose track
of which Hub port is operating at which data rate.
Also note that while this procedure should enable you to use most
1200-bps serial peripherals, it won’t work for some of them, because a
few types of devices draw more power from the serial port than the
Extender can provide.
If you would like to use a 1200-bps serial peripheral such as an industrial trackball
with your ServSwitch Brand CAT5 KVM/Serial Extender system, attach the
peripheral to the serial port of the ACUSREM Remote Unit. Then take these steps
to set the Extender to operate at 1200 bps on the line that leads from the
KVM/Serial Local to that Remote Unit, referring to Figure C-1 on the next page:
1. Unplug both the Local and the Remote Unit, so that both are powered OFF.
2. Following the instructions (including those in the Caution notice) at the start
of Chapter 3 , open the Remote Unit. Follow the instructions in your Extender
manual to open the Local.
3. If the Local is an ACU1008A Local Unit (for a one-to-one KVM/Serial Extender
system), it will have a single serial daughtercard. If it’s an ACU1006SRA
KVM/Serial Local Hub, it will have six such daughtercards—one for each of
its ports. There are a pair of empty jumper posts labeled “Baud” on each of
these cards. Each pair of posts has a jumper “hanging off” one post. On the
card in the Local that controls serial communication to the 1200-bps
peripheral’s Remote Unit, move this jumper so that it connects the two posts.
This will override the 9600-bps or 19,200-bps data-rate setting in the Remote
Unit, so that the Extender system operates at 1200 bps; in a Hub-based
system, the rate change will affect
that link only . (Move this jumper back to its
original position at any time to set your system back to 9600 or 19,200 bps.)
