Modules

SIMPL Windows provides programmers with a number of Crestron modules as well
as a predefined directory to store user created modules.
Crestron modules are prepackaged logic programs. A Crestron module is a set of
pre-written and debugged logic used for controlling a particular device or performing
a function. The use of modules saves programming and debugging time since a large
portion of the symbol – signal functionality already exists inside the module. Thus
even beginning programmers can control very complex equipment by using the
correct Crestron module.
It is important to remember that modules (unlike symbols) do not have optional
inputs or outputs. Because of this, all input and output signals must be defined.
Module input signals that are not used can be given a 0 (zero) as a signal name. This
will force the signal LOW and will not affect the module. Output signals are
different and should be given unique names such as "no_connect1, no_connect2..."
Do not force unused output signals states with 1 or 0, this may affect how the module
operates internally.
Programmers can create their own modules and store them in the User Modules
directory. Alternatively, programmers can use an existing Crestron module as a
starting point, and edit them to match their specific needs.
For detailed information about Crestron and user modules, refer to the SIMPL
Windows help file.

Communication Settings

You must establish a valid connection between the control system and the PC before
you can upload programs or otherwise communicate with the processor. This is
accomplished using either a serial (RS-232) or TCP/IP connection. If you are
connecting to the control system for the first time, you must use RS-232. You can
then configure the IP settings of the control system for subsequent connections over
Ethernet.
For RS-232 communication, use a DB9 straight-through serial cable to connect the
COMPUTER port on the control system to one of the COM ports on the PC.
