Crestron SIMPL™ Windows

 Software

The purpose of this section is to provide programming information about various 
devices that can be added to a SIMPL Windows project. 

Serial drivers in SIMPL Windows are used to control communications to Cresnet 
communication devices (e.g., ST-COM, CEN-COM, CNXCOM-2, CNCOMH-2, 
etc.) 

Not all devices support all of the above options. To determine which features a 
particular device supports, drop the device into a SIMPL Windos project and open 
one of the ports in Program Manager’s Detail View. 

[TX$] is a serial string (which can come from symbols like Transmit Analog 
[Speedkey: TXA]). Information on the serial string attached to this input is 
transmitted out of the COM port, at the COM port parameters specified for that port 
in Configuration Manager. If there are no symbols driving this input, it may be left 
blank 

[RX$] is a serial string (which can be routed to symbols such as Serial to Analog 
[Speedkey: OP103]).  Information on the serial string attached to this input is 
processed by the symbols that this string is driving. If the received data is not 
processed by other symbols, this ouput may be left blank. 

[BREAK] generates a BREAK on the transmit pin of the associated COM port. 
There are several different kinds of BREAKs. Some BREAKs are 17-20 bits of low. 
Some are generated continuous logical low as long as the BREAK line is held high. 
Consult the documentation for each specific device to know whick type of BREAK it 
generates. Some RS-422 based devices use the BREAK for synchronization before 
communicating other data. If BREAK characters are not going to be generated, this 
input may be left blank.
