The standard system is supplied in an ABS transit case, together with any communications adapt-
ers ordered. Any additional lengths of signal cable are packed separately.
3.1. Communications With PC
The M
IDAS
ECM can be set up and interrogated using the DataLog Express software supplied
(DataLog 400 or DataLog Pro for more complex systems). Please refer to the separate manual for
details of how to use the software.
To connect the instrument directly to a PC for RS232 communications, use the 3m Y lead supplied.
This lead is fitted with a 10 pin Subconn type connector, which should be plugged directly into the
connector on the top of the housing (or to a length of signal cable). The lead also features 2 x
4mm bunch pins for application of external power if required and a 9 way D type connector which
should plug directly into a spare communications port on the back of the PC.
If non-RS232 communications are to be used, via the optional RS485, RS422 or FSK methods,
then the appropriate adapter should be used. Each adapter is supplied with an alternative Y lead,
which should be connected as follows:
If FSK option is fitted, baud rate will be fixed at 34800
