X-light V2
TP
Regardless of the controlling application, the settings for the COM port used to connect to the X-LIGHT
V2
TP
are as follows: 9600 baud, 8 data bits, 1 stop bit, No parity, and no flow control.
Devices
The X-LIGHT has three individual devices that can be actuated to affect the light path. Each device has
a single capital letter name (Device ID), which is used to address the individual device with the commands
that are described later in this manual. The number of allowable positions differs for different types of
devices and they are all listed in the chart below.

Note: the baud rate pos. 4 is only for Xlight unit 20Krpm .
When the X-LIGHT is first turned on all the devices are initialized to their “Home Position” listed in the chart
above. The “H”, Home command can also be used to return all the devices to these positions.
When you switch-on the power supply the self-test of all functions are running.
Command Conventions
Regardless of their origin, all commands must adhere to the following conventions:
1) All commands must be terminated with a carriage return <CR>. The X-LIGHT II will not even
attempt to recognize any characters sent on the serial port until it receives a <CR>.
2) Syntax errors in commands are known by receiving a plain <CR> response (no command echoed).
3) When the entire command string (all strings preceding the <CR>) has been processed the entire
command string is echoed back to the PC host. The exceptions are the lower case commands.
Lower case commands signify the command requests information from the X-LIGHT. The
responses to these commands append the requested information to the original command.
Erroneous commands, either invalid Device ID or invalid parameters, are simply ignored but are
echoed back to the host as they were sent; in any case the board answer with a CR.
