connected from a Local card. The default port can be changed here too.
Note that you only need to supply a password in the commands shown in Table 6-1
if you previously created a Terminal Password. See step (6.E) on page 6-7.) If there is
no password assigned to the card, omit the brackets [] shown in the examples.
To control OPTIMOD-PC externally, establish a Telnet/SSH connection and issue
commands and parameters, either by typing them directly into a Telnet/SSH client or
by placing them within batch files. Then process them with a scriptable Telnet/SSH
client that supports this operation, such as PuTTY, along with its companion com-
mand-line interpreter, Plink. Both of these applications are available for free
download from the following web site:
http://www.chiark.greenend.org.uk/~sgtatham/putty/
Automating control changes is possible using the Windows Task Scheduler to launch
batch files at the desired time.
Custom third party applications can be developed to use this protocol. Additionally,
you can include this protocol in an existing application by using small subsets of the
standards-based Telnet/SSH protocols directly, or for simplicity, by using scripting or
by calling batch files with a Telnet/SSH client such as PuTTY along with its compan-
ion command-line interpreter, Plink. Scripting eliminates the need to develop net-
working code or otherwise contend with complex, limited-function Microsoft Win-
dows specific programming APIs, like the Windows Audio Mixer. Developing a third
party application or including the protocol in an existing application eliminates hav-
ing to install and configure additional applications. Using small subsets of the stan-
dards-based Telnet/SSH protocol allows more operational flexibility without a sys-
tem performance hit and simplifies development compared to proprietary OEM
APIs.
Commands are case-sensitive and must be entered exactly as shown. Replace
"[password]" with the actual password of the card being addressed. If there is no
password assigned to the card, omit the brackets [] shown in the examples.
Table 6-2 describes the available command strings and their functions. To demon-
strate this functionality, you may type the commands directly into a Telnet/SSH cli-
ent terminal and see OPTIMOD-PC confirmation and status messages.
