2.4 Power LED
The CAN series products (8123, 8223 & 8423) need 10 to 30 VDC power
supplies, (Please note that other slot modules, inserted in, will also consume
part of the inputted power). Under a normal connection, a good power supply
and a correct voltage selection, as the unit is turned on, the LED will light up in
yellow. If it can’t work, please check with local agents or resellers for more help.
