Interactive Operation
4.1
Keyboard and Floppy Emulation
The VS 710 can be temporarily linked with the keyboard and diskette drive
of a separate PC / programming device (host PC) for operator control of the
VS 710. For this you need an RS232 connection, the emulation program
HOSTKEY.COM, and a VGA monitor connected to the VS 710.
HOSTKEY is started on DOS from Tool Diskette 1 on the host PC. Once
emulation has been started up, the interaction switches from the host PC to
the VS 710 (specifically, to the monitor). Tool diskette 1 can now be
removed and replaced by another diskette.
4.2
HOSTKEY Program
HOSTKEY emulates floppy diskette drive A: and the host PC keyboard as
components of the VS 710. For this you need a functioning serial
connection, and HOSTKEY must be activated before rebooting the VS 710.
The program is supplied on a diskette along with the product and is started
from the host PC.
The VS 710 monitor takes over the function of operator monitor once the
connection has been established.
1.
Insert the HOSTKEY diskette in the diskette drive of the host PC,
having connected the host PC via the RS232 interface.
2.
Start HOSTKEY from diskette drive A: at DOS level or from the DOS
box under Windows 95/98.
Note
You can also start HOSTKEY indirectly using the REMOTE.BAT
program. Before HOSTKEY starts using the maximum transmission rate,
you will explicitly be asked for a specific interface.
Note
The HOSTKEY.COM file is only to be run under the Windows 95,
Windows 98 and Windows ME operating systems.
The HSTKEYNT.EXE file is only to be run under the Windows NT and
Windows 2000 operating systems.
