Channel Usage – Set to either Intrusive or Passive as desired.
•
- Passive (Non-intrusive) operation "piggy-backs" reprogramming data onto
normal payload data streams, thus allowing payload data to continue
uninterrupted, but will be slower than intrusive operation. This mode requires
payload data to be sent so that the reprogramming data can be carried. See Table
5-3 for reprogramming times.
- Intrusive operation means that the payload application data will be interrupted
while programming data is sent over the air. This is the fastest method of
programming radios over the air, but it comes at the cost of interruptions in the
primary use of the radio network. For best results, data polling should be stopped
during Intrusive Reprogramming. See Table 5-4 for reprogramming times.
Block Size – Sets the overall block size (in bytes) of each data packet. Default setting is
•
512.
Auto-Reboot – When enabled, the remote radios will automatically reboot after a
•
firmware image upgrade. If disabled, the newly loaded image will not become valid until
the remote radio is rebooted manually.
Packet Size – Specifies the size of the reprogramming data packets. Default size is 40.
•
Retry Count – Specifies the number of times each transmission is repeated. Default
•
setting is 3. Decreasing this value will decrease reprogramming times, but increase the
chance of a remote radio not properly receiving a packet.
Download Delay – Introduce a time delay before reprogramming begins. Typically, it is
•
set to Short, but may be increased incrementally by selecting one of the extended delay
times from the drop-down box (Short, Medium, Long, None)
