In Lambda 10-3’s programmed with firmware version 1.21 or later, the parallel port is
enabled for use.
When configured to do so, the Lambda 10-3 microprocessor sets the PARALLEL port 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 discusses 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 that apply to use of
the SERIAL and USB ports, also apply to the PARALLEL port.

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.
