NetLinx Programming

NetLinx Programming

You can program the MAX unit by using the commands in this section to perform a wide variety of operations using Send_Commands and variable text commands. A device must first be defined in the NetLinx programming language with values for the Device: Port: System.

In these programming examples, <DEV> = Device. The term <D:P:S> = Device:Port:System.

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

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 // Device number

INTEGER Port // Port on device

INTEGER System // System the device belongs to

}

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 the system and Port specifications are omitted, (e.g. 128), system 0 (indicating this system) and port 1 (the first port) is assumed. Here's the syntax:

NUMBER:PORT:SYSTEM

where:

NUMBER:	16-bit integer represents the device number
PORT:	16-bit integer represents the port number (in the range 1 through the number of
	ports on the device)
SYSTEM:	16-bit integer represents the system number (0 = this system)

Port Assignments

The following table outlines the Ports used by the MAX-CSE and MAX-CSD10 by referencing their Port # assignments:

MAX-CSE Port Assignments

Port/Description	ICSP Port #
Video Encoder	1
RS-232/422/485 Serial Port	2
IR/Serial Port	3
I/O Port	4
IR RX Port	5
LCD Display	6

ALL Commands used on the MAX-CSE are case sensitive and must be entered as shown within this section.
