SERVSWITCH™ BRAND CAT5 KVM/SERIAL/AUDIO EXTENDER
1. Quick Start Guide
Configuring the Extender
Configuring the ServSwitch™ Brand CAT5 KVM/Serial/Audio Extender involves
setting some internal controls. Read the next couple of paragraphs, and if you find
that you’ll need to change configuration settings, follow the procedure that’s listed
afterward. (If you’re not certain which Extender model you’re working with, refer
to
Chapter 3
.) Here’s what you need to consider:
•
How far will the CAT5 cabling run between the Extender’s Local and Remote
Units?
If it will be 100 m (330 ft.) or less, you don’t need to set anything. If it
will be 100 to 200 m (330 to 655 ft.), install jumpers on the three
right-hand
post pairs in each set of three cable-length jumper posts (JP3 through JP5) in
the Remote Unit. If it will be 200 to 300 m (655 to 1000 ft.), install jumpers on
the three
left-hand
post pairs in each of these sets of cable-length jumper posts.
See Figure 5-1 in
Section 5.1
.
•
What keyboard key do you want to be the “hotkey” to start the Extender’s
keyboard commands?
If the keyboard’s right [Ctrl] key can be used for this
purpose (which it probably can if none of your software or hardware looks for
a single isolated press and release of this key), you don’t need to set anything.
If you need to press and release this key by itself to trigger some function of an
attached KVM switch or of a software program on an attached computer
(common on Compaq
®
Alpha
®
, HP
®
, and other workstations for which right
[Ctrl] maps to the [Compose] key), move position 2 of the DIP-switch labeled
SW1 on the main circuit board inside the KVM/Serial Extender’s Remote Unit
to ON. Refer to
Section 5.2
.
•
Does the Extender need to amplify microphone input from the remote site?
This should not be the case if you are connecting a PC’s sound card (which
can amplify the signal itself) to the local CPU’s audio jack on the Local Unit. If
you are connecting some kind of recorder or sound-input device that can’t
amplify the input signal to that jack, and you’re using a nonamplified
microphone at the remote site, install the jumper on the jumper posts marked
“MIC” on the audio daughterboard inside the Remote Unit. Refer to
Section 5.3
.
To get at the internal controls, open the Extender Unit while it is powered off—
taking all reasonable precautions against static electricity—by unscrewing the four
screws on its case and lifting off the top half of the case. For more information
about configuration, refer to
Chapter 5
.
