Installing and Operating the ServSwitch™Jr. LP
These directions are for a typical “direct plug-in” installation of a monitor, keyboard, and mouse to a PS/2®type CPU.
At the CPU end, the extension cables have 6-pin mini-DIN keyboard and mouse connectors.
If you have different typesof equipment, or want to use different extension cabling, please call Black Box Tech support.
After making sure that your computers and
monitor are turned OFF:
Plug the video cable of your monitor
into the port on the rear panel of the
Jr. LP marked .
Plug your keyboard into the port in the
same area marked .
Plug your mouse into the port in the same
area marked .
Plug your speakers in the same area
marked .
Attach the DB25 end of one of the PS/2 type
extension cables to the Jr. LP’s CPU 1 port.
Run this extension cable to the Video-
output, keyboard, mouse, and speaker
ports on the computer.
Repeat steps and for your other
computer, attaching the cable to the
Jr. LP’s CPU 2 port.
Now turn your computer and monitor ON.
The Jr. LP will turn ON automatically.

INSTALLING AND OPERATING THE SERVSWITCH™JR. LP
Command Keystroke Sequence Description
Select CPU [Ctrl] 1 or
[Ctrl] 2 Switch your monitor, keyboard, and mouse access to the specified computer (1 or 2)
Switch to the Other
CPU [Ctrl] [+] or [Ctrl] [ -]Switches to the other CPU for monitor, keyboard, and mouse access
Start Scanning [Ctrl] S Turns Scan mode ON, causing the Jr. LP to scan back and forth between the
two CPUs.
Stop Scanning [Ctrl] X Turns Scan mode OFF, giving you access to the CPU being scanned when
the command is entered. (Scans can also be stopped by entering a Select
CPU or Switch CPU command.)
Reset Keyboard
and Mouse [Ctrl] R Causes the Jr. LP to reset the attached keyboard and mouse.
Send Null Byte to
Resync Mouse [Ctrl] N Causes the Jr. LP to send a “null byte” to the CPU’s PS/2 mouse port. Enter this command to correct the selected CPU if it gets “out of sync” with the
mouse.
Reset Computer’s
Mouse Port [Ctrl] O Causes the Jr. LP to try to get the currently selected CPU to reset its PS/2 mouse port.
Identify ROM [Ctrl] I Causes the Jr. LP to report the version of ROM it is using. Enter this
command if you are asked to do so by a Technical Support person.
Keep Settings [Ctrl] K Enter this command after you enter any of the four commands listed below
(It saves the new settings to nonvolatile memory):
Set Scan-Delay
Time [Ctrl] Txx [Enter] (xx = 1 to 15) Sets the time, in seconds, that the ServSwitch Jr. LP will pause at each CPU when scanning.
Set Mouse Mode [Ctrl] Qx [Enter]
(x = 0, 1, or 2) For the selected CPU, Q1 translates PS/2 mouse input to serial mouse output, Q2 forces PS/2 wheel-mouse output, and Q0 resets to normal PS/2
non-wheel-mouse-output.
Set Keyboard Mode [Ctrl] Mx [Enter]
(x = 1,2, or 3) Tells the Jr. LP the keyboard mode (1, 2, or 3) of the currently selected CPU.
Set Keyboard
Typematic [Ctrl] Axxx [Enter] (xxx = decimal value
from 0 to 127; see
below)
Sets the keyboard typematic (automatic key-repeat) function of the currently
selected CPU, as described in the table below.
The keyboard typematic is an internal seven-bit value maintained by some keyboards. The last five bits control the typematic
rate (how often a held-down key repeats); the first two bits control typematic delay (how long a key must be held down before it
starts to repeat). Add the two values together to get the value of the argument for the Set Keyboard Typematic command:
Delay Bits:
Dec. Bin. Delay Rate Bits: Dec. Binary Rate Dec. Binary Rate Dec. Binary Rate
