1. Broadcast Retry: You can set the radio to attempt up to 8 retries.
2. Synchronization Timeout: You can set this field from 250–500 ms with
50 ms increments. This setting applies to the repeater and slave radios
only. The repeater or slave radio will start the synchronization
procedure and scan for the master once it is out of sync with the master
for this amount of time.
3. Force a join with the specified parent subnet: This field is only available
if the radio is set as a slave station. If not selected, the slave radio will
try to talk to any repeater or master in a network.
4. Enable power save channel scan: This field is available if the radio is set
as a slave or repeater station. If the radio loses sync with the master, it
begins to continuously scan for the master signal. Enabling this feature
allows you to set the radio to scan only at specified intervals (0–60 s).
5. Enable Deep Sleep Mode: This field is available only if the radio is set
as a slave station. This feature causes the radio to power down once it
has completed its transmission. Insert an RS232 space signal on RTS
pin to bring the radio out of sleep mode.
6. Packet Size: Designate the size of the data packets used by the radio in
its transmission. In noisy environments, it is often beneficial to use
smaller data packet sizes to increase the chance that data is received at
the other end.
7. Radio Transmit Power: Reducing the transmit power ensures that the
radios do not overwhelm each other when used in close proximity.
Follow these guidelines when setting radio transmit power:
