Configure the PC4
The PC4 is a small, plug-in RS-422 cable driver board that drives long cables up to one thousand feet using differential signaling to improve noise immunity. The PC4 can be used with the E2, E3, H1, H3, S1, and S2 encoders. Each board has a 5-pin socket designed to plug into the 5 pins of the encoder.
On the output side, the PC4 can use ribbon cables for lengths up to 100 feet; twisted pair cables are recommended for longer lengths. An optional 120 Ω terminating resistor may be placed across each pair on the receiver side of the cable, matching the cable's characteristic impedance. When calculating the power requirements of the encoder side of the cable, including the current consumed by the module, the driver IC and any terminating resistors. Be sure to supply sufficient voltage to compensate for the voltage drop due to the resistance of the power and ground wires. If an RS-422 receiver chip such as 26C32 is used on the receiver side of the cable, a 0.1uF ceramic monolithic bypass capacitor across +5V and ground located within 1 inch of the receiver chip is recommended.
