The Lambda 10-2 microprocessor sets the PARALLEL port, by default, as the input source
upon startup and anytime the ON LINE key is pressed. An appropriate command from the
remote computer through the PARALLEL port will also set that port as the active input
source and the display on the controller will reflect that change on its bottom line. The
PARALLEL port will remain active until an appropriate command is sent from a remote
computer through the SERIAL port or until the LOCAL key is pressed on the controller
keypad. This chapter will discuss these connections and the structure of the data that is
required from your computer for controlling the filter wheel(s) and shutter(s) through the
PARALLEL port. Many of the details about the command structure will also apply to use of
the SERIAL port for remotely controlling the Lambda 10-2.

The parallel interface connector on the back of the cabinet is a DB-25 connector. This port is
designed for connection to a standard parallel port on a computer and is not to be connected
to any other type of device. The pin assignments for this connector are, as viewed from the
back of the unit, shown below.
