From a DIRECTV Tech. Bulletin Issue# 5 dated 4/25/2011 regarding the SWiM-16 and 32:
SWiM 32
----------
*SWiM 32 has 2 power options for the 4 SWiM 8’s built in the chassis: a 24v DC F-type connection adaptor or a 24v DC pin type adaptor; the F-type connection is the preferred choice for reliability reasons.
*The SWiM 32 does not need a polarity locker unless it is used in a distribution system, but a 20v DC power supply must be used on first SWiM 32 inline to power the SL3 or SL5 SLIMLINE LNB.
*The SWiM 32 can be cascaded 2 deep. There is no DECA bridge on a SWiM 32 between the 4 independent SWiM modules so the SWiM 32 will not share callback or allow Whole Home DVR functionality between the 4 independent SWiM modules.
*Each independent SWiM module on a SWiM 32 Multi-Switch has its own SWiM output port; however an independent SWiM power supply should never be used on any of the independent SWiM ports as power is supplied by the 24v DC power supply to the whole chassis.
*SWiM 32 is manufactured by UNITRON.
*SWiM 32 has two FLEX ports for 95 (WORLDDIRECT) or 72.5 orbital slots. When using the SWiM 32 as a standalone device, the 95 sat MUST be plugged into the flex port 2 as this version does not perform auto-detect.
*As with all SWiM installations, BBC’s are never used, and all receivers must be SWiM capable.
*The H25 receiver that will only work in a SWiM installation will work with the SWiM 32.
*Each independent SWiM module has an off air input to allow for services in the 54 Mhz to 806Mhz frequency range. A tri-plexer is used to separate these signals from the DIRECTV signal in the
customer’s home.
