transmitted preamble sequence. To prevent synchronization by unwanted signal, a time
delay, called
“
Rx On Delay
”
, is needed between squelch open (the point of busy
detection) and data signaling path to Modem (see Figure 5.3.). If insufficient preamble
code is released from another radio, data loss will occur by missing synchronization. So,
a minimum period of time is required for synchronization, this is given by modem IC
specification and you can adjust this value within the limited range. Detailed other
parameters for ACC-513/514 will be given in the next section.
