Clear-Com HME DX210 Operating Instructions
Multiple Base Station Daisy-Chaining
Two or more DX210
base stations can be “daisy-chained” using the 2-W connector ports on the rear panels
of each base station (following Clear-Com
®
/
RTS
®
standards), or
two base stations (not more) can be “daisy-
chained” together with cables connected to the
4-W
or
AUX
connectors.
NOTE 1:
DX210 does not provide 2-wire line power, therefore, 2-wire power bypass must be used.
NOTE 2:
For AUX type daisy-chaining, the cable connectors must be 3-pin XLR.
●
If using 4-wire connection, use cable with In/Out
crossed, as shown to the right.
(
An Ethernet crossover cable will not work.
)
●
If using 2-Wire connections, open each base station and set jumpers JP1 (IC1) and/or JP2 (IC2)
in
all base stations
to ON for
power detect
bypass. Set jumpers JP5 (IC1) and/or JP6 (IC2)
in only one
base station per channel
for termination. Refer to
Appendix C, page 23
.
●
Perform base station registration for each base station. Refer to
Appendix D, page 24
.
