AdderLink Installation and Use Page 21
keyboard/mouse port commonly found on the back of laptops. The wiring scheme
used on a few of these 'Y' cables confuses the AdderLink into thinking that it is being
connected to the computer's serial port and consequently prevents correct
operation. When option switch 4 is set to the ON position, RS232 mouse detection is
disabled. This enables a computer connected via a 'Y' cable or adapter to be used
with the AdderLink without problems.
XL unit – Switch 5
If this switch is set to the ON position then the remote unit will go directly into
compensation / configuration mode at power on. This enables a password locked
XR unit to be reset. See section 3.10 for further details.
XL unit - Switch 6
This switch controls the video mode on the AdderLink Gold and has no function on
the AdderLink. The video picture from the computer connected to the XL unit may
be broadcast to the monitor connected to the XL unit and the monitor connected to
the XR unit. Alternatively the video picture may be displayed on only one of these
monitors at a time. The video picture is directed to the monitor whose keyboard and
mouse most recently had control of the computer that is connected to the XL unit. If
this switch is set to the OFF position then the video will be broadcast to both
monitors. When set to the ON position, video will be sent to the monitor whose
associated keyboard and mouse last had control of the XL end's computer.
XL unit - Switches 7 and 8
These switches have no function on the AdderLink. On the AdderLink Gold, the
switches select the timeout period for switchover of computer control between the
local (XL) and remote (XR) units. The timeout period is the duration of keyboard and
mouse inactivity that must be detected before the AdderLink Gold will switch control
between the local (XL) and remote (XR) user console. The AdderLink Gold allocates
control of the computer to the first keyboard / mouse set (local XL or remote XR)
that sends keyboard or mouse data. The other keyboard / mouse set is then
prevented from accessing the computer until no keyboard or mouse data has been
received for the timeout period. Once a timeout has occurred either keyboard /
mouse set may access the computer on a first come first served basis.
