You can communicate with the DigiVAC via any computer on the network us-
ing a Telnet program. Software can be downloaded from any computer on the
network, as long as that computer has a ‘TFTP server’ installed. You can
download the Solarwinds TFTP server from:
http://solarwinds.net/Tools/Free_Tools/TFTP_Server/Download.htm
This TFTP server is also included on the DigiVAC Product Support CD in
folder: software/GUI_utils/.
This method of updating software has the following advantages:
• Two or more DigiVACs on a network can be updated simultaneously
• Connecting DigiVACs to a network allows them to be configured
remotely
• In the future it could allow service engineers or distributors to update
application software remotely
• Application software can be downloaded much faster
Refer to Section 4.4.4 for a detailed description of how to update software us-
ing this method.
4.4.2 Updating Software With a Memory Card
An SFM (Serial Flash Memory) Card (914-440) can be used to transfer appli-
cation software to the GUI CPU.
The SFM Card plugs directly into the side of the GUI CPU and the application
software can be transferred to the CPU automatically. In addition, the applica-
tion software can be transferred manually, using a computer connected to the
DigiVAC in terminal mode.
The procedure for automatically transferring application software from the
SFM Card to the CPU is described on the CPU cover.
SFM Cards can be easily updated with new versions of the application soft-
ware, using an SFM Parallel Port Programmer (914-442A).
4.4.2.1 Copying Software onto an SFM Card
In order to save the latest version of the application software onto an SFM
Card, an SFM Parallel Port Programmer is required.
Figure 4:8 Copying Software onto an SFM Card
Procedure
1. Plug the SFM Parallel Port Programmer into the parallel port of the
computer.
2. Insert the SFM Card into the SFM Parallel Port Programmer.
Glossary
Terminal Emulator:
A terminal
emulator is a software applica-
tion that allows a computer to
communicate with other equip-
ment. Terminal emulators nor-
mally use an RS232 serial
connection between the two
devices.
Telnet:
This is a type of terminal
emulator that is specifically de-
signed to allow a computer to
communicate with other equip-
ment across a network. Telnet
can be used to control the Digi-
VAC’s boot firmware from a
computer connected to the same
network.
Telnet is provided free with
Microsoft Windows®.
TFTP server
: This is a software
application that runs on a
computer on a network and
controls the transfer of files.
Different types of TFTP server
are widely available as Free-
ware, which can be downloaded
from the Internet.
Parallel Port Programmer:
This
device plugs into the parallel
port of a computer and allows
application software stored on
that computer to be copied onto
an SFM Card.
The parallel port programmer is
supported by Microsoft Win-
dows
®
95, 98 and ME for soft-
ware V1.2j and earlier; and
Windows
®
95, 98, ME, 2000 &
XP for Software V1.2k on-
wards.
The parallel port programmer
contains two CR 2032 watch
batteries. To change the batter-
ies, hold the programmer with
the red LED uppermost, then
ease apart the two halves of the
body. The new batteries should
be fitted the right way round, as
shown on the programmer’s
PCB.
