Single Wire Multiswitch (SWM) technology allows you to distribute satellite and Over The Air (OTA) antenna signals on a single cable. For instance, you can combine your Sat 1, Sat 2, and the OTA cable into one cable. In addition, a house that was wired with a single cable can now have up to 8 tuners anywhere in the house.
Currently the SWM capable Receivers are:
Standard Definition Receiver (Single Tuner): D12
Standard Definition DVR (Dual Tuner): R16, R22
HD Receiver (Single Tuner): H20, H21, H23
DirecTV Plus HD-DVR (Dual Tuner): HR20, HR21, HR22, HR23
+ Older "Legacy" Receiver Tuners must be connected individually to the Legacy ports.
+ The SWM5 can serve up to 5 SWM tuners plus 2 Legacy tuners. For example, it might serve (2) HR20's, (1) H20's, and (1) TiVo.
+ The SWM8 can serve up to 8 SWM tuners plus 3 Legacy tuners. For example, it might serve (3) HR20's, (2) H20's, (1) TiVo, and 1 older receiver.
+ "SWM" is now used instead of "FTM". Older units may have a label of FTM instead of SWM but they mean the same thing.
Warning 1: The minimum 15' cable length from Power Supply to SWM.
Warning 2: The Power Supply's Red SWM (FTM) output must go to the SWM or it can destroy all receivers!
Warning 3: Only an experienced installer should install a SWM. DIRECTV may install at no cost.
1. Log satellite transponder and OTA signal strength.
2. Power down and unplug all Satellite Receivers.
3. Connect (4) Dish AT-9 (or AU-9) RG6 to SWM satellite inputs (max 40'). Flex 1 & 2 are for other satellite dishes.
4. SWM8 Optional: connect Antenna to SWM8 OTA input.
. . SWM5 Optional: connect Antenna to the Combiner Diplexer Ant input.
5. Connect SWM receiver SWM input to the power inserter white IRD connector, or to line from splitter. (Optional: Connect SWM Receiver's SWM Input to Diplexer Sat Out.)
6. Optional: Connect Diplexer Ant to the receiver's OTA.
7. Optional: Connect Diplexer Sat to the receiver's SWM/FTM input.
8. Optional: Connect Diplexer Combined Input to Power Supply White IRD connector.
9. Optional: Connect SWM Legacy outputs to up to (3) legacy tuners, 2 for SWM5.
10. Remove previously used BBC's from receivers and put back in box. DO NOT USE BBC's.
11. Connect Power Supply white IRD to SWM Receiver SWM1 input (or optionals splitter or diplexer).
12. Plug in SWM8 Power Supply (optional: into same UPS/surge for HR20.)
13. Verify green LED through vent slot. Wait 5 minute.
14. Power up legacy receivers one at a time allowing full boot and verify transponder signal strengths.
15. Plug in receivers. They should begin rebooting automatically.
16. Check the satellite signal strengths on each satellite receiver. Check FTM signal strength on SWM receivers.
17. Check signal strengths on OTA channels (if you are using Over The Air inputs).
18. As always, make sure all connections are tight, avoid splitters and diplexers if possible, and always follow grounding instructions.

Are all diplexers and splitters pretty much the same the same?
→ NO! See Choosing the Right Splitter
→ Diplexers can work with SWM modules. Here is the comparison chart: Diplexers
