Stage C - Connections
The naming of the LOCAL and REMOTE modules relate to their proximity to the
computer system. Hence, the LOCAL module connects directly to the system,
while the REMOTE is at the other end of the twisted pair cable and attaches to
the keyboard, mouse, etc.
Connections at the LOCAL module
Multi-cable connection
Most of the connections between the computer system and the LOCAL module
are made via the supplied multi-cable. This has a single connection to the
module, is two metres in length and splits out to the keyboard, video, mouse
and (for the X2-Gold) microphone and speaker ports of the system.
1 Attach the
supplied multi-
cable to the 25-
way socket at the
end of the LOCAL
module.
2 At the other end
of the multi-
cable, attach
the keyboard,
mouse and video,
(plus optionally
on X2-Gold, the
microphone and speaker) connectors to the appropriate sockets at the rear
of the computer system. On most systems the appropriate ports should be
labelled and colour coded in a similar way to the cable connectors:
Monitor (video) Blue
Keyboard Purple
Mouse or Mid green
Speaker or
SPK
Light green
Microphone or
MIC
Pink (or maroon)
Serial cable connection
The X2-Series extender modules offer the option to attach an RS232 serial
device (such as a touch screen input) via the remote link. The link supports
software or hardware handshaking up to a maximum baud rate of 56Kb/s. To
make the serial connection between the LOCAL module and your computer
system, use the supplied serial link cable.
1 Attach male connector
of the serial link cable
to the 9 pin port on the
LOCAL module,
labelled .
2 Connect the other end
of the serial link cable
to the appropriate serial
port of the computer
system.

Twisted pair connection
The link between the LOCAL and REMOTE modules is made via twisted pair
cable, specied to Category 5 or higher. Ensure that the total twisted pair cable
length (including patch boxes) does not exceed 300 metres.
1 Insert the connector from
the twisted pair cable link
into the socket marked
‘TO REMOTE’.

Optional power connection
The LOCAL module usually derives its power from the keyboard connection of
the host system. If the keyboard connection will not be used then you will need
to use an external power supply of the same type used for the REMOTE module.
These are available from your Adder supplier.
