APPENDIX B: MULTIPLE BASE STATION DAISY-CHAINING
Two or more DX410 base stations can be “daisy-chained” together with cables connected to the 2-W connectors 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.
A maximum of 4 base stations can be used in one system, spaced apart a minimum of 12 inches.
NOTE 1: DX410 does not provide 2-wire line power, therefore, 2-wire power bypass must be used.

If using 4-wire connection, use cable with In/Out crossed, as shown to the
right. (An Ethernet crossover cable will not work.)
h
If using 2-Wire connections, open each base station and set jumpers JP1
(A) and/or JP2 (B) in all base stations to ON for power detect bypass. Set
jumpers JP5 (A) and/or JP6 (B) in only one base station per channel for
termination. Refer to Appendix C , next page.
