Encoder RS485

For encoders that use an RS485 interface, configure the data pins for full-duplex

operation with combined TX and RX data or half-duplex operation with separate TX

and RX data. You may configure each channel independently. Table 11 lists the

jumpers to set for each channel. Table 12 lists the jumper positions for encoder RS485s.

Out means fit no jumper; in means fit a jumper.

Encoder Interface

The Multiaxis Motor Control Board supports RS485, resolver, Hall effect and

quadrature encoders. You can configure each channel independently to support one

of these encoder standards at any one time. Table 13 lists the jumpers to set for each

channel. Table 14 lists the jumper positions for encoder interface selection.
