UDM-RX02N NetLinx Programming
Overview
There are a select number of NetLinx CHANNELs, LEVELs and SEND_COMMANDs recognized by the
UDM-RX02N.
NetLinx programming is supported only if the UDM-RX02N is connected to the UDM-0808-SIG Hub (a
native NetLinx device).
The main Device SEND_COMMANDs are described on page 50.
IR SEND_COMMANDs are described on page 52.
Serial SEND_COMMANDs are described on page 55.
Device Numbering
In NetLinx Studio’s online device tree, the UDM-0808-SIG is listed as a device with a single port, and each
UDM-RX02N receiver connected to the Hub is listed as a separate device immediately following the Hub (the
default device number for the UDM-0808-SIG is 05600 - refer to the Device Numbering section on page 13 for
details).
Note that the device number for each UDM-RX02N currently connected to the UDM-0808-SIG Hub is
automatically designated a device number, based on the device number of the Hub to which it is connected,
and the number of the UDM OUTPUT port on the Hub (1-8) to which it is physically connected.
Therefore, it important to avoid assigning device numbers that will conflict with this auto-numbering scheme.
Reserve the eight device numbers following the UDM Hub’s device number assignment for up to eight UDM-
RX02Ns.
In NetLinx Studio’s online device tree, each UDM-RX02N receiver shows three ports (FIG. 51)
These three ports relate directly to the three types of NetLinx commands recognized by the UDM-RX02N:
Port 1 - SEND_COMMANDS/LEVELS (Video Control and IR Receive)
Port 2 - SERIAL (RS232) SEND_COMMANDS
Port 3 - IR SEND_COMMANDS (IR Output)
Only RX units that are physically connected to the Hub will be represented in the
Online Tree.
