… and if TCP/IP communications were selected, it would look like this (fictitious IP address shown):
Definition name
Each COM Settings definition requires a unique name. A field for this data can be
found at the top left of the
COM Settings
window. We recommend choosing a name
that reflects either the location of the control system (such as “SUITE3”) or its
function (such as “PHONEBOOK”).
This name is used in the server’s user interface to identify the system data structure.
It is also sent along with error messages to the actual control system to identify the
source of an error resulting from processing one of the system-level signals defined
herein.
Control system generation
Here you specify the type of control system. The server uses this information to take
into account minor differences in the way the older generation of Crestron control
systems functioned in terms of timing and data capacity.
Communications mode
In this frame you choose RS-232 or TCP/IP connections. If you choose RS-232, note
that hardware handshaking is strongly recommended. The details are described in the
Server Side configuration sections for RS-232 (page 21) and TCP/IP (page 22).
System-level signal definitions
In this window you can also define optional system-level signals by checking the
appropriate boxes. Doing so defines a special signal block which communicates with
its own
Intersystem Communications
symbol in your SIMPL Windows program.
In this case, you should also fill in the
Signals
field, as follows:
Signals
This is the
offset
of the
Intersystem Communications
symbol in your SIMPL
Windows program. The connection’s signal block must not overlap any other signal
block (channel 1 of) these COM settings or else the server protocol will not be able
to be started.
Refer to the “Signal Reference” section, which begins on page 78, for more
information on each of the signals listed in the window.
Signal Block Configuration and Definition
Data structures called a “signal blocks” are created on the server, each
communicating with its own
Intersystem Communications
symbol on a control
system.
A signal block’s
configuration
includes behavior options as well as optional signal
definitions. The signal block’s
definition
refers to its list of input and output signals,
including fixed as well as optional signals.
Each active signal block must reference a “COM Settings” data structure which
defines a connection to a control system. See “COM Settings ,” above.
