INSTALLATION
The standard system is supplied in an ABS transit case, together with any
communications adaptors ordered. Any additional lengths of signal cable are packed
separately.
3.1 COMMUNICATIONS WITH PC
The M
IDAS
WLR can be set up and interrogated using the DataLog Express software
supplied. 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 adaptor should be used. Each adaptor is supplied with
an alternative Y lead, which should be connected as follows:
