3 Communications protocol
3.1 USB
The MSE colorimeter can be connected to any USB host. The colorimeter
is a USBTMC compliant device which is a standard USB class device and
device drivers for this class are available for most popular operating
systems (also embedded). This makes the MSE colorimeter directly
usable in popular programming languages like NI's Labview and
Labwindows but als C++, Visual basic, C#, Java etc. The MSE colorimeter
has two interfaces build in, which require a different device driver to be
used.

Admesy bootloader
(USB RAW device driver Vendor ID : 0x23CF, Product ID 0x0E92)

MSE colorimeter
(USBTMC device driver Vendor ID : 0x23CF, Product ID 0x0EA0)
When the MSE colorimeter is connected to the host, it will start the MSE
colorimeter firmware. As soon as the firmware is idle to receive
commands, the Power LED goes to the on state. The Admesy bootloader
is a RAW USB device and in order to use this device in Windows, a driver
must be installed which is supplied by Admesy. Besides upgrading to new
firmware, it is also allowed to downgrade firmware in case this is required.
Note that older firmware also may require the use of older software
libraries and/or executable versions of software. The MSE colorimeter is
USBTMC compliant and can be used with libraries that contain a USBTMC
compliant driver like NI-VISA. The MSE colorimeter is a USB 2.0 Full
speed device. In case a USB host is detected, it is assumed that the MSE
colorimeter operates only via USB.
3.2 RS232
MSE commands are equal for all interfaces. Note that for high speed
transfers it is best to use USB. When RS232 will be used, the device mode
should be set to RS232. This is done via software and stored in the device
EEPROM memory.
