Hardware 2.1

The BMCM can be used with NMR or EPR Variable Temperature Units. See the ECL level table below.

Table 2.1. VTU ECL Requirement

Firmware 2.2

The BMCM module works fully only with the firmware version 2.7 (970219 or lat-er). An older firmware works but it is not possible to change the gas flow in real time with the flow knob on front plate. To change the gas flow you must select a new flowrate and then switch off and on the temperature unit to update the flow-rate.

New firmware installation 2.3

When the variable temperature unit is equipped with an older firmware version, please follow these instructions to download the new firmware with a PC:

Connect the serial port (COM1) of a PC to the RS232 connector of the tempera-ture unit. Use the standard serial cable which is delivered with the temperature unit.

Switch on the main power of PC and temperature unit.

Copy the files LOADER.EXE and AP970219.HEX from the floppy disk to the PC hard disk.

From the hard disk, run LOADER.EXE AP970219.HEX AAAA and follow the in-structions given by the program.
