Socket Radio
Frequency Diversity
The socket radio frequency diversity is three separated frequencies in low end, middle and high end of the band.
During offline unlinked mode, the radios listen for an RF packet on one of the three channels. After a the RF receive
timeout period, the radio moves on to the next frequency and listens for a valid RF packet on the that frequency. The
process continues cycling through all three diversity frequencies. If a valid packet is addressed to the radio, it replies
on the same frequency. The receive timeout is restarted with the reception of a valid packet addressed the
receiving radio.
If a socket radio has an RF packet to transmit, it transmits the packet on the current receive frequency. If a valid
ACK is received in the RF ACK timeout, the radio stays on the same frequency and resets the receive time out. If no
response is received the radio attempts to transmit on the next diversity frequency.

Table 1 Channel Frequencies
Over the Air Channel Change Operation
The Over the Air Channel Change command is sent from the Initiating radio to the Subject Radio. After the
command has been sent and acknowledged, both radios will then change to the new channel. If a link is not
reestablished on the new channel, both radios return to the original channel.
Time Slot Architecture
There are four basic functions of the software: RS232 Receive, RF Transmit, RS232 Transmit and RF Receive. The
functions are performed sequentially in a timeslot structure that varies, depending on the activity.
Time Slots During Idle State
When the Socket Radio is idle, it monitors both the incoming RS232 and the incoming RF input. The Socket Radio
will respond as directed by either the RS232 input or a RF transmission. While idle, the timeslot timing is shown in
Figure 1.
