3.3 Keyboard NUM, CAPS and SCROLL lock indicators
The AdderLink uses the keyboard NUM, CAPS and SCROLL lock lights to indicate various operating conditions as follows:
NUM, CAPS and SCROLL lock lights flash in sequence
The AdderLink flashes the NUM, CAPS and SCROLL lock lights in sequence on the keyboard connected to the XR unit to indicate that the AdderLink is in video compensation / configuration mode. The NUM lock light comes on first with CAPS and SCROLL off. Then the CAPS lock comes on with NUM and SCROLL off and finally the SCROLL lock comes on with NUM and CAPS off. The rate of flashing indicates the level of video compensation applied by the video compensation amplifiers. A slow flash rate indicates a small amount of compensation (short twisted pair cable distance). A fast flash rate indicates a greater level of video compensation for longer cables.
NUM, CAPS and SCROLL lock lights flash together
The AdderLink Gold flashes the NUM, CAPS and SCROLL lock light together on the keyboard attached to the XL unit or the keyboard attached to the XR unit to indicate that the other keyboard currently has control of the computer connected to the XL unit. These lights will stop flashing when a timeout has occurred and the computer connected to the XL unit is free for use by either keyboard/mouse set.
