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)
I
Data to be saved in a Spreadsheet file format or not.
I
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.
e.g. type:BM25Load 1 1 (note parameter spacing).
The program should be run before the BM25 is switched on.
To start the program from the C:\ prompt,
1. Type CD\BM25 press <ENTER> The cursor prompt changes
to:C:\BM25
2. Type in the command words BM25Load followed by <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 appear. Every time
the program is run, the name and path will default to
C:\BM25\loaded.dat. A new file path name may be entered by
overtyping the default. Use the ↓↑ keys to move to the next entry. If
0 = No spreadsheet file.
