CHAPTER 4 – Operating the AF910
Methods of Operation
The AF91x can be operated in various ways. Communication via a serial port is always
necessary to control basic functions and to setup various parameters. The unit has two
methods for controlling or indicating where the focus point is. The first is the analog
output signal which can be monitored to determine when focus has been achieved. The
second is the motor control functions which provide both step and direction outputs to
control a focusing motor.
Software Quick Start
Once the unit is installed on a video system, proper power has been applied and the
communication lines connected, the system can then be run via the communications port.
The included software is meant to be a quick start way of operating the unit. After the
software is installed run it and select the appropriate communications port if necessary. If
the unit is not found on any of the communication ports, double check the connections.
The AF91x software communicates with the unit at the default baud rate of 57,600. Be
sure the communication speed has not been altered. See the command set section for
more details of setting different communication speeds.
