NETS
ENTRIES FOR A NET
E
NVOY™ TRANSCEIVER REFERENCE MANUAL 169
Stations with the NET programmed only send a response to a NET call if:
• their self address is included in the NET Members entry for the NET, that is,
they are a member of the NET, and
• the Response entry for the station is set to Send
You can set the following:
• If you want to know with which member stations you have linked, select Only
if response.
The calling station makes the call to the NET using the best channel, on average,
for all NET members. If there is no response to this channel, the calling station
selects the next ranked channel and attempts the call again, and so on until at
least one response is received. Any member station detecting the call responds,
if they are enabled to do so, then the calling station completes the link.
Non-member stations with this NET programmed also enter the link, but as they
are not members, they do not send a response.
NOTE: If you set the Link entry to Only if response, you must be sure
that there are stations in your NET that are set to respond to a link
request. If the calling station does not receive a response to the
call after trying all channels for the NET, it terminates the link
establishment process.
• If you want to send a NET call to all stations with the NET programmed, but
you do not need to know which of the member stations enter the link, select
Even if no response.
The calling station makes the call to the NET using the best average channel for
all NET members. All stations detecting the call enter the link, if enabled to do
so.
• If you want to send a NET call to all stations with the NET programmed without
the delay of the link establishment process, select Immediately.
In this case, the calling station establishes an implicit link with any stations
programmed with the NET that detected the call. There is no 3-way handshake.
Response
CAUTION: If the Link entry is set to Only if response, you must ensure that at
least one member station is set to receive and respond to a call from the
NET.
The Response entry sets whether or not called member stations respond to NET
calls during link establishment. Generally, you would set the Response entry to
Send, so that there is confirmation of the station entering the link. If you do not want
the called station to transmit on air, set the Response entry to Don’t send. If a
station is set to not respond, it still enters the link when it receives the
acknowledgement from the calling station.
