(Master)
Termination resistors required at both ends of the
network receive data signals to match the impedance
of the cable (between 100 and 500 ohms). Jumper pin
13 to 9 on the C-more 6” Micro-Graphic Serial Port2
15-pin connector to place the 120 internal resistor
into the network. If the cable impedance is different,
then use an external resistor matched to the cable
impedance.
