CHAPTER 3: Configuration
3. Configuration
The users’ manuals for the various ServSwitch™ Brand CAT5 KVM Extender
systems and/or their Locals identify the cables you’ll need to connect various types
of equipment to the system, so this guide will only deal with configuring the
Remotes and attaching devices directly to them.
The two-position DIP switches on the Micro Remotes are external; see
Section 3.1 . All of the Remote’s other configuration controls are internal, but
should only need to be set once; see the relevant sections starting with Sections 3.2 .
To get at them, first open the Remote by unscrewing the four screws on its case
and lifting off the top half of the case. When you’ve finished setting the
configuration jumpers and switches as described in the rest of this chapter, close
the Remote by replacing the top half of the case and screwing the screws back in.
CAUTION!
The Remote’s circuit boards can be damaged by static electricity, so take
every reasonable precaution against it. At the very least, discharge yourself
on a metallic surface before opening it; if possible, stand on an anti-
static mat and wear a grounding strap or anti-static gloves.
3.1 Setting the 2-Position DIP Switch on the Micro Remotes
There’s a two-position DIP switch on the bottom of the ACUMREM and
ACUWREM Micro Remote Units, and there are six of these two-position DIP
switches on the bottom of the ACU1006MRA and ACU1006MRVA Extender Micro
Remote Hubs. Position 1 of each switch governs the Micro Remote’s video
equalization for that link, while position 2 controls how the Micro Remote handles
keyboard-command recognition:
• Position 1 (video equalization): The Micro Remote contains video-equalization
circuitry which compensates for the loss in image quality that occurs when you
drive video across cables longer than 25 m (80 ft.). If you’ll be running cable
to such distances between your Local and the Micro Remote, you need to
configure the Extender for extra equalization before you install it.
To do this, set position 1 of the Remote’s DIP switch for that link to UP
(OFF) if you’ll be running cable for that link up to (but not more than) 25 m
(80 ft.). To boost the equalization if you’ll be running cable between 25 and
50 m (80 and 160 ft.), move position 1 to the DOWN (ON) setting.
If you are not running the cable too far but your video looks bad no matter
how you set this DIP switch, the problem is almost certainly being caused by
one of two things. First, check your interconnect-cable routing—does the cable
pass close to a motor, generator, fluorescent lights, etc.? Second, check the
