Hello,
I would like to read data from a Philips MX750 via the MIB interface.
We connected the recommended adapter cable to the interface. Unfortunately, we did not have a BeagleBone Black available at the time, so we connected the adapter directly to the laptop’s USB port using another adapter.
Our theory was that in the service menu of the Philips monitor, the driver for the MIB port can be configured and that by selecting the driver “DTEXP 1”, the MIB interface would behave like a normal serial interface and could therefore be used as a standard serial connection.
With this setup, the software is able to connect to the monitor, but we always receive a checksum error.
The baud rate is set to 115200 on both devices.
Is a BeagleBone Black mandatory?
Do we need to select a different driver on the monitor?
We have already tried many things, but so far without success.
Hi Janek,
To connect to the MIB port, you will need a custom RJ45 to DB9 cable as mentioned here: https://sourceforge.net/p/vscapture/discussion/general/thread/cb369fa9/ The pin out wiring in MX 600-800 series is different from that of MX400-550 series, ensure this is correct.
The BeagleBone is not a necessity, the RJ45 end connects to the monitor while the DB9 end connects to the serial port in your PC or laptop. The monitor should also be configured for serial data output, go to Service Menu, Hardware, Data Export 1 and 2 to 115200 . Then in Interfaces menu select MIB interface driver DtOut1.
In case this doesnt work, you could try the LAN interface for data capture.
