OVERVIEW
The remote control of the Lambda 10-3 can be achieved by issuing commands on a remote
computer and transmitting them to the Lambda 10-3 over a serial
serial serial serial (RS-232) or USB USB USB USB
(Universal Serial Bus) connection. In versions of the Lambda 10-3 programmed with version
1.21 or later of the firmware, remote control can also be achieved via a parallel connection.
This chapter provides a description of these commands and how they are used. Limited
remote control can also be achieved with a TTL connection, a description for which is
provided later in this manual.
The following table shows how remote commands are categorized.

Description
Filter commands
These are commands used exclusively for controlling
filter wheels.
Shutter commands These are commands used exclusively for controlling
shutters (SmartShutters and/or Vincent shutters).
Special commands These are commands for the general control of the
Lambda 10-3 controller, and are not specifically related to
either filter wheels or shutters.
Most of the commands described in this chapter are ones that are sent from the computer to
the Lambda 10-3. Some of these commands will cause the Lambda 10-3 to return certain
special codes or one or more bytes of data. Some commands must be followed by one or more
bytes containing parameters. For each byte sent to the Lambda 10-3, that same byte is
echoed (transmitted) back to the remote computer as confirmation that the byte was
received. The echoing back of command bytes in no way indicates validation of a command or
parameter, but is rather an acknowledgement from the controller that the byte was received.
When the Lambda 10-3 controller finishes performing the task associated with a command
(or command followed by one or more parameter bytes), an ASCII carriage return (CR, 13
decimal, or 0D hexadecimal) is transmitted back to the host computer as an indication that
function associated with the command has completed and that the controller is now ready for
another command. This echoing back of bytes sent by the remote computer to the controller,
and the return of an ASCII carriage return after a command’s task is complete is the same
for the serial, USB, and parallel interfaces.
