2 Interfaces
2.1 USB interface
The USB-B connector is used to connect the MSE to a PC/Laptop. USB
connection is preferred to ensure high speed data transfer of colour
measurements. The MSE uses the USBTMC class protocol and can
therefore be used directly with third party provided VISA compliant libraries
like NI-VISA. The MSE can be used USB powered in case the host
provides enough current. Normally every USB 2.0 host should be able to
drive 500mA. Non powered USB-
HUB’s mostly do not supply enough
current. It is therefore recommended to use powered USB-
HUB’s only.
2.2 RS232 interface
RS232 is provided to connect the MSE colorimeter to any host that doesn't
provide USB or for which no USBTMC drivers exist. Using RS232, the
high speed options of the colorimeter are still available, only transfer of
data to the host is reduced in speed. It is recommended to use USB in
case the high speed sampling options are needed.

In both USB and RS232 modes, USB is still active but when only USB is
used, it is recommended to set it to USB mode so that the MSE responds
in the fastest possible way to commands. The operating mode must be
selected via the Admesy Colorimeter PC application.
