The recommended cord is the BF640A to connect the DAD104 to the RJ45 network jack, KB171. Cords and
jacks must be ordered separately.
One modular jack is provided at the back of the DAD104. Use modular cables with straight through pin
configuration only! An 8-pin (RJ45) modular jack (KB171) and cord (BF640A) are required for connection to
the network.
