dp34 installtion problem

[rtchin]

Having problems installing a dp34 switch. exisiting, working setup, dish 1000, 2 irds (vip211, 381). i added a dp34 switch to try and add a 3rd receiver. 1 tiwn lnb, for 119/110, one dual lnb for 129.

this is what i did. i disconnected the 129 from the twin input. i ran the two out cables from the twin into the dp34, port 1 and 2. i ran a separate cable from 129 to the dp34, port 3. hooked up the vip211 to test on output port 1 from the dp34.

ran check switch. comes back with:

input 1: x x nc
input 2: 110 all twin
input 3: x x nc

dp34 is used, but from a working system.

i take out the dp34 and put all back to original (129 out, to twin in...twin out to receiver), i get 119, 110, 129...all working.

any suggestions? bad switch? any help is appreciated.

Try swapping the cables at the switch. Put 110 on port 1 and 119 on port 2, just to test it. If 110 fails on port 1 then you have a bad port 1. Do the same with port 3, that will give you an indication if the switch is bad.

You could also clear the switch matrix on the receivers.

Disconnect the satellite feed and run check switch.
Connect satellite feed and run check switch again.

ok, so i'm still fiddling with it this morning. new info. i decided to just try disconnecting the 129 to the dp34 all together. i put the twin out port 1 into port 2 on the dp34, the twin out port 2 into port 3 of the dp34.

check switch...

now it sees:

input 1: x x nc
input 2: 110 all twin
input 3: 119 all twin


port 1 must be dead on the dp34...right? or am i missing something here?

thanks for any insight anyone can give.

 

[rtchin]

thanks Randall, looks like port 1 on the switch is the problem. i guess that's what happens when you buy stuff off ebay.

 

[rtchin]

just doing some more testing. i connected 129 directly to port 3 on the dp34, check switch find 129 on port 3. looks like port 1 is dead.

Yep, looks like a bad port 1. I would try to contact the seller and see if he can get you another one or refund your money. It's worth a try.

DP34s can be finnicky at times.
On post 1, try a longer center conducter with a new connector.

I have ran into the same problem.

 

[rtchin]

i'll try that. what are we talking about? the center conductor sticking out like half an inch?

One other possibility, Dish does not recommend using a DP34 with a DPP Twin.

I have had nothing but problems with DPP Twin hooked up to DP34sw

How did the problems manifested? For what he's describing I don't think the problem is the DPP Twin.

Several T/C's that myself and other techs went on had the same issue. DDP Twin with DP34sw and always 1 or 2 satellite's missing. Replaced DPP Twin with two duals everything ok. Tested twin back at shop everything ok. On the T/C all cabling was replaced and power receptacles tested to rule out any issues with them.

ok, i tried with a long center conductor. no luck still. luckily seller will exchange.
