upgrade, it is necessary to establish communications between the PC and the
touchpanel.

Establishing Communications

When communicating with a touchpanel from a PC, one of three communication
methods can be used.
Indirect RS-232 serial communication via control system
•
Direct RS-232 serial communication
•
TCP/IP communication
•
Indirect Serial Communication via Control System
The procedure in this section provides details for RS-232 communication between
the PC and the touchpanel via the control system. This method can be used to
communicate with the control system directly and with a touchpanel via the control
system's Cresnet connection.
Refer to the following figure for a typical connection diagram connecting to a
touchpanel via a control system.
Indirect Serial Communications Setup Connections
1. Ensure that all devices are connected to the control processor and the
control processor is connected via serial cable to the PC.
2. Open Crestron Toolbox and click Tools | Manage Address Book to display
a list of available devices. Select Serial on COM1 as the connection type.
Serial on COM1 is an entry in the DefaultAddressBook that is included
with Crestron Toolbox.
The PC communication settings specified here should match the protocol
that the control processor expects. The usual settings are as follows:
• Port = COM 1 through COM 8. Select the correct COM port on
the PC.
• Baud rate = Auto-Detect.
• Parity = None.
• Number of data bits = 8.
• Number of stop bits = 1.
• Hardware handshaking (RTS/CTS) enabled.
• Software handshaking (XON/XOFF) not enabled.
