COMM Module Implementation

Overview

The PTE-300 control capabilities for camera functions include:
The PTE-300 is controlled with a Cafe Duet COMM module, available from www.amx.com.

Preparing the PTE-300 for Communication

Setting Device ID

The PTE-300 is a special case as far as device IDs are concerned. Instead of having a native device ID
already integrated into its firmware, the COMM module sets up the PTE-300 to be assigned a virtual
device ID by the master. This virtual device ID may be changed as circumstances warrant. Please see the
ITG Programming manual for more information.

Device:Port:System (D:P:S)

A device is any hardware component that can be connected to an NetLinx or ICSNet bus. Each device
must be assigned a unique number to locate that device on the bus. The NetLinx programming language
allows numbers in the range 1-32,767 for ICSNet.
NetLinx requires a Device:Port:System (D:P:S) specification. This D:P:S triplet can be expressed as a
series of constants, variables separated by colons, or a DEV structure. For example:
STRUCTURE DEV
{
INTEGER Number
INTEGER Port
INTEGER System
}
The D:P:S notation is used to explicitly represent a device number, port and system. For example,
128:1:0 represents the first port on device 128 on this system.
If a device is declared in a NetLinx program with just the Device number (System and Port are
omitted), the NetLinx Compiler assumes it has a Port number of 1 and a System number of 0.
However, you should convert all existing device declarations using the D:P:S (Device:Port:System)
notation. This enables certain NetLinx-specific debugging features and can help pinpoint other possibly
obscure errors.
