Reply-Only Reference

In general, a Zaber device will reply to an instruction using the same command number as the instruction itself. However, there are occasions (such as when the user turns a manual control knob) when the device may transmit data without first receiving a request from the controlling computer. This type of reply may be considered to be a triggered reply as opposed to a requested reply. In this case the device uses a “reply-only” command number to distinguish the reply from those requested by the controlling computer. The meanings of these replies and their corresponding data are given below.
