there is not a “Party-Line Enable” within Eclipse, if several users of
intercom stations connected with Eclipse need to hear each other as
well as the wireless FreeSpeak beltpack, another procedure will need
to be added. Within the configuration software, the user would create a
new party-line label, with members including the desired intercom
stations and the particular FreeSpeak 4-wire port. That label would
then be assigned to a key on each of the intercom stations, allowing
connection with the FreeSpeak 4-wire port and the other members of
the new party-line.
Within the FreeSpeak Basestation configuration software, the user can
adjust the input and output level for that port. Alternately, the input and
output levels can be adjusted on the FreeSpeak basestation for the
particular 4-wire port, using the front-panel display. Repeat the
procedure for each FreeSpeak 4-wire port that is connected with the
Eclipse system.
CONNECTING WITH OTHER DIGITAL MATRIX INTER-
COM SYSTEMS
Because FreeSpeak features standard 4-wire ports, with an input pair
and an output pair, virtually any 4-wire signal can be connected with it.
Make sure to properly match the input and output pairs between the
digital matrix port and the FreeSpeak 4-wire port (see diagram below).
The pinouts for the first two 4-wire ports contain both audio and data
connections, though the data connections are not currently used.
Those pinouts are shown in the following table.
Table 4-3: Pinouts for Connecting to Other Digital Matrix Intercom Systems
The remaining two 4-wire connections are audio only, and the data
connections are unterminated (see Table 4-2).
Within the configuration software of the other digital intercom system,
configure its connected port to 4-wire or similar. Adjust the input and
output levels either at matrix side or within the FreeSpeak front-panel
display for the particular FreeSpeak 4-wire port.
