Setting the Target System ID and Target Network ID (A-1519/A-1520
Targets, A-910-900/2.4, A-910-2.4ZB)
The System ID is a Radio Network Address that is used by the Radio Communications Protocol to filter
unwanted data from other radio transceivers and targets using a different address. Only targets and radio
transceivers that are set to a matching System ID can communicate with each other.
Because no two targets with the same System ID can transmit simultaneously, it is necessary for each
target to be programmed to respond only when it is being addressed. The Target Network ID is the target
address on the communications network. Under Host (computer) control, the radio transceiver transmits a
message called a
polling request
that contains the Target Network ID of one specific target. All targets
receive all polling requests, but only the target with a Network ID matching the ID contained in the
polling message will reply (Transmit Data to the Host).
There are three rotary DIP switches located on the
right side of the target, shown in Figure 10:
•
The uppermost switch sets the System ID.
•
The two lower switches are used to set the
target network ID.
Setting the System ID
Note:
Before selecting a System ID, ensure that it is
not already in use by another system within the
radio coverage area.
Using a small screwdriver, rotate Switch 1 to align
the arrowhead with the System ID number (0-9).
Figure 10 shows the System ID switch set to 1.
