wo Wire Systems transmit and receive on the same pair of wires, which can lead to trouble. The
host must not only disable its transmitter before it can receive data, it must do so quickly, before a
drive begins to answer a query. Fortunately, the BLu servo drives include an “transmit delay”
parameter that can be adjusted to compensate for a host that is slow to disable its transmitter. This
adjustment can be made over the network using the TD command, or it can be set using the Quick
Tuner software. It is not necessary to set the transmit delay in a four wire system.
Getting and Connecting an RS-485 2-wire adaptor to your PC
(800-450-2001) works well. It comes with everything
you need. Connect as follows:
