2.3 Addressing the LEDs on the Front Panel
The LEDs are addressed via the "CO100" connector (see ""CO100" Connector"
on page 13).
The LEDs require around 10 mA to light up and have dropping resistors of 825
Ω
for operating with 5 V. If the LEDs are operated at another voltage, appropriate
dropping resistors must be connected in series on the relevant module.
