4.1.6 Termination and Biasing

The radio modem has built in 1.2 k

Ω

pull-up and pull-down resistors R17 and R14). There

is also a built in 120

Ω

termination resistor (R21). These resistors are located on the PCB

behind the cover. Termination is switchable using DIP Switch Position 3. To enable the
termination, set switch 3 to ON “Termination IN”. To disable the termination, set switch 3
to OFF “Termination OUT”.

It is possible to use different value resistors by removing the surface mount components
and placing through-hole resistors (R16, R13, and R19) in the space provided. The
surface mount components are located directly opposite of the through-hole pads that are
visible.
