CHAPTER 3: Installation
3.4 Connecting the Extender to the Duo
NOTE
This “-R2” version of ServSwitch Duo Extender can’t be used with the
original (non-R2) ServSwitch Duo.
Attach all of your local equipment to the ServSwitch Duo as described in the
section titled “Systems with a Single Duo and Directly Attached User Stations” in
the Duo’s manual. Leave everything powered off, and make sure the ServSwitch
Duo Extender, your remote monitor, and any CPU attached to the Extender are
powered off as well.
Run eight-wire (four-pair) twisted-pair cabling from the RJ-45 jack in the
ServSwitch Duo’s user port #1 to the matching jack on the ServSwitch Duo
Extender. (Do
not
attach these jacks to a LAN; you could damage the Duo or
Extender and possibly the network as well.) Category 5 twisted pair will give the
best results in lengths up to 200 m (655 ft.), but you should be able to use
Category 3, 4, or 5e if you keep the distance short (not more than 100 m [325 ft.]).
Avoid
using cabling rated as “Level 6,” “Level 7,” etc., for data rates above
155 Mbps; the large differences between the twist ratios of the wire pairs in these
cables cause the video signals from the Duo’s CPUs to get out of sync with each
other.
The twisted pair can be a single continuous length of cable if that’s the best
option. But this kind of cable is often already installed in buildings and terminated
at data-wiring sockets in various locations. If twisted-pair cable is preinstalled at
your site, you can run patch cables from the Duo and Duo Extender to these
sockets and set up a direct one-to-one connection between them using the patch
panels in your wiring closets, which will probably be much more convenient.
A sample system using a single Duo and Duo Extender is shown in Figure 3-1 on
the previous page.
CAUTION!
Even though the cabling and connectors might be the same, do
not
connect a ServSwitch Duo or Duo Extender to your LAN. Doing so will
damage the Duo/Extender and might damage the network as well.
