4.1 UNIT IDENTIFICATION AND STATUS
Each Guardian has addressing capability which is used for diagnostics and remote
commands
only .

ID Number
This value (maximum 1023) is assigned at the factory but may be modified using the Field
Programming Software. The ID Number is used to uniquely identify the Guardian for remote
commands and Offline Diagnostics. The ID Number may have values within the range of 1
to 4294967295 but
multiples of 1024 should not be used

Short ID
This value (maximum 1023) is the low order 10 bits of the ID Number. It is used to identify
online diagnostics only. It may not be modified directly using the Field Programming
Software; it is always derived from the ID Number. All units within a network should have
unique Short ID numbers to avoid ambiguity in Online Diagnostics reports.
The Guardian Field Programming Software may be used to check the value of the Short ID.
When setting up a network, we recommend checking each unit to make sure there is no
duplication of Short ID numbers. Duplications may be resolved by changing the Short ID
Number.
If ID Numbers are set within the range of 1 to 1023, the ID Number and the Short ID will
always have the same value (see Table 1-4).
4.2 DIAGNOSTICS
Guardian units continually monitor and report on their environmental and operating
conditions.
4.2.1 Online Diagnostics
Information is automatically sent by each unit at the beginning of every transmission.
May be disabled for back compatibility with Dataradio T-Modem 96 or Motorola RNet 9600.
Online Diagnostics (statistics) require the use of a network configuration such as that
specified in the “Network Using T-Base” or “Network Using GUARDIAN for Online
Diagnostics” sections. Online diagnostics do not interfere with normal network operation.
Online diagnostics provide four types of information:

DC Input Voltage

Transceiver Temperature

PA Forward Power

PA Reverse Power
4.2.2 Offline Diagnostics
Offline diagnostics are statistics returned in response to a specific request to a particular
station. The use of this feature requires temporary suspension of user network operation.
Offline diagnostics provide information that is displayed via the Offline Diagnostics utility.
Offline Diagnostics gather and displays five types of information:
