RS 232 socket
The RS232 socket is optically isolated from all other circuits
within the BM25. It is therefore safe to connect a computer to
this socket while tests are being performed. Removal of the
plastic dust cover to expose the RS 232 socket will not impair the
IP54 rating of the instrument, but replacing the cover after use
will reduce the possibility of contact pin corrosion. Test results
are sent to the RS 232 socket every 5 seconds. The Baud rate is
9600, and the format of the output data is comma delimited
ASCII. The BM25 DOWNLOAD program as supplied with your
instrument is suitable for receiving this data.
Installing the Program
The process of installing the BM25 DOWNLOAD program onto
the hard disk of your PC only takes place once. You will only
have to repeat it if you wish to transfer your copy of the program
to another computer. The program will run using DOS Version
3.2 or later versions, and requires a minimum of 1 MB of
memory. Most modern PCs will meet this criteria. With the
diskette in the disk drive, at the DOS C:\> prompt type:
A:Install A: C: <press ENTER>
This creates a directory called BM25 on your hard disk and
copies the program from the diskette in your drive to that
directory. If you want to use a disk drive other than A, use the
letter of the drive you are using instead of A.
Connecting the Instrument to a PC
Connect one end of the 9 way cable to the RS 232 plug on the
face of the instrument, and the other end to a serial (COM) port
on the PC. Note which PC port you have selected.

Running the Program
In order to run, the software will require the command words
BM25LOAD followed by 2 parameters. These parameters are:
∗ The PC COM port identification. (0 to 4)
∗ Data to be saved in a Spreadsheet file format or not.
1 = spreadsheet (.wks)
For example if you are using number 1 port of the PC, the first
number following the command word BM25LOAD would be 1
(preceded by a space).
If you want to save the measurement data in Spreadsheet
format, the second number following the command word
BM25LOAD would be 1 (again preceded by a space). If not, the
number would be 0.
The program should be run before the BM25 is switched on.
To start the program from the C:\ prompt,
Type CD\BM25 press <ENTER> The cursor prompt
1.
changes to:C:\BM25
Type in the command words BM25Load followed by
2.
<space> parameter <space> parameter.
3. When the software is running, the screen colour changes to
blue and a file path screen will appear. If the spread sheet
file format has not been selected, only one file name will
0 = No spreadsheet file.
e.g. type: BM25Load 1 1 (note parameter spacing).
