3.0 CONNECTING THE HSM100 TO A P.C.
The HSM 100 should be connected to a spare RS232 serial port on the P.C using the supplied cable.
Please ensure that the selected port is not used for other applications and that no device drivers are loaded
which may conflict with the ports use (DOS Mouse drivers, modem software etc.)
For information, the HSM100's data socket is wired as follows;
HSM CONNECTOR IBM 9 WAY FEMALE
1 TXD 2 RXD
2 DTR 1 DCD, 6 DSR, 8 CTS
3 GND 5 GND
4 RTS 4 DTR
Data will be transmitted from the HSM100 every 1-2 seconds whilst it's RTS line (Pin4) remains high.
4.0 STARTING THE PROGRAM
To initiate the 'HSM' software, double-click the 'HSM 100' Icon within the 'HSM for WINDOWS'
program group.
All menus and options are accessible using mouse based operations. If you are new to the Graphical user
interface of the Windows environment, please refer to your Microsoft Windows documentation.
5.0 PROGRAM CONFIGURATION
Program set-up details defining the screen layout, data parameters and serial port connection are saved
within a file HSM.INI. To prevent unauthorised operators modifying the software's configuration and
thereby introducing potential problems, it is recommended that the 'HSM.INI' file is made 'read-only'.
Whilst this file is in a read only condition, all menu options used to access editing functions are removed
from menus. The read only attribute may be set from Windows `File Manager' or `Explorer'.
6.0 USING HELP
The program has been written such that the user should find the application both quick to learn and easy
to use. As with all new software packages the user should spend some time experimenting and becoming
familiar with menu functions. A 'Help' 'Contents' window provides a list of all major Help topics.
7.0 SERIAL PORT SELECTION
The program will be supplied configured to expect the HSM 100 to be connected to the P.Cs 'COM1'
serial port. The serial communication port settings can be changed by using the 'Edit Data Input',
'Properties', option from the main 'Options' menu. The HSM 100 communicates at 1200 Baud, with 8
Data bits, no parity, one stop bit and no flow control.
Save any set-up changes such as the serial port details using the 'Save Configuration' option from within
the 'Options' menu.
