Wiring Advice?

[lumpkin666]

I'm working on wiring up a single receiver to my system, and was hoping for some advice/feedback/direction as I procede. I've done some reading, and "think" this will work, but I'm not so sure (especially afer my recent discovery).

I have a BUd with an actuator arm and a BSC-621 c/ku lnbf with internal diseqc. I want to move this with a moteck v-boxII. I also have a 36" dish on an SG2100 H-H mover with an Invacom QPH-031 quad lnbf (circular and linear lnbf). And finally, I have two stationary KU Linear lnbf dishes for a couple sats that are out of line-of-site for the 36" dish.

I read that the ecoda 0/22 switches with pass diseqc commands, so I plan on putting that near the receiver, and running the 0mhz side to the 36" dish's sg2100. From the 2100, I will connect to a diseqc and then connect to 2 legs of the invacom and both of the stationary dishes. The 22mhz leg of the ecoda will connect to the moteck and from there to the bsc-621 c/ku lnbf with internal diseqc.

My thoughts are that the ecoda should pass diseqc movement commands to the correct mover (sg2100 or moteck), and the diseqc swiches will then give me the desired lnbf.

The one finding that I've seen so far (still waiting on a couple parts to put this all together), is that when I send 0mhz tone to the ecoda, the sg2100 works fine, and I see my lnbfs past the 2100. BUT, when I send 22mhz tone, the SG2100 still works! (can't seen the lnbfs though). Should the ecoda be passing the diseqc positioning commands to the sg2100 eventhough its on the 0mhz side? Is this happening because the 0/22mhz tone is sent after the diseqc positioning commands?

Any thoughs/advice/etc concerning this setup would be greatly apprecaited.

Adding to my message -
I was a bit confused by various posts, and believed that the BSC-621 had an internal Diseqc, but it appears that it's a tone switch (according to the install instructions). Obviously the 0/22 tone switch is going to have a problem working through a single leg of my ecoda 0/22 switch. So I'm thinking that I can bypass the BSC-621's internal switch (as was confirmed possible by others here), and hook the individual C and KU lnbf outputs to a diseqc switch instead.

See updated diagram attached.

The BSC 621-2 is a Universal on the KU side so it has a 22k built in. But both models (621 and 621-2) have Diseqc commands built in (if you use the loop through). C-Band is port 1 KU is port 2

If you use the internal switch on the C/KU LNB then you cant have a Diseqc in line.

I see. The BSC 621 install instructions that I had been looking at actually linked to the bsc 621-2 instructions. Thereby causing my confusion about the tone switch. So I should be okay, without bypassing the internal switch (if the rest of my setup is actually feasible!)

 

[Mr Tony]

correct. The 621 (the standard KU LNB portion) will only need one cable from the LNB to the switch (22k switch)

The picture looks feasable and should work as long as the 22k switch you use is the right one. Most wont pass diseqc commands.

Thanks Iceberg! I appreciate your input. I do believe that the ecoda 22k switch that I am using will do the trick. I already have it inline before my sg2100 motor and diseqc on the 36" dish and I'm moving the motor and switching lnbf's fine.

The only thing that bugs me about the ecoda and passing diseqc commands is that it appears to be passing the diseqc commands to the sg2100 regardless of which output I have selected in the menu. It doesn't seem to be passing the diseqc commands to the selector switch when on the wrong output (which is good).. but the fact that my sg2100 is moving no matter which output I select makes me worried that both my dishes will be moving all the time (not a BIG deal right now, but will pose a problem when I start introducing more lnbf's and duals/etc for other receivers)

Thx again!

diseqc commands are based on 22khz tone's so I dont beleive that you'll be able to use two motors on the same ird. give it a shot though, definitly worth a try.

I would try the sg2100 on usals and the vbox on v1.2 (it only supports v1.2) using both motors on v1.2 might confuse the ird even more, lol.

I had thought that 0/22k switches were designed to switch between to ports based on either no signal or 22khz signal sent to it. I purchased an ecoda 0/22k switch which is designed to allow diseqc commands down the line past the switch. I did this so that I could pass diseqc commands to two separate motors, and then select from different ports on the downstream diseqc switches.

It appears that my 22k switch is switching, because my downstream diseqc switches are selecting the appropriate lnbf's. The weird thing (that I had not noticed since the dishes are not within view of my receiver), is that indeed BOTH motors move regardless of the 22k switch setting. I had "thought" this was happening before I added the 2nd motor, but assumed that I was incorrect after installing the 2nd since the switch between dishes seemed pretty instantaneous (there was no obvious delay for the motor to reposition the other dish when switching back and forth). However, after motoring way over east last night on one dish, I happened to be in the back yard and noticed that both dishes were pointed east. After a little investigation, it appears that indeed both dishes are moving at all times eventhough they are behind different legs on a ecoda 22k switch and each is assigned a different value (one 0k and the other 22k). The big issue for me is that one of my motors reaches its limit before the other, and I don't want to strain it by moving it past that point.

Is there something I'm missing about my setup? How can I prevent both motors from moving at the same time? Shouldn't the 22k switch be filtering motor commands from the leg of the switch that is not supposed to be active (as set in the 0/22k settings for the sat)? Are the positioning commands being sent and processed before the 22k commands?

As suggested, it might help to use usals on the sg2100, but for some reason, I could never get get usals to move the motor at all (initially went in and set my values and save them, but the motor never did anything), so I've been stuck with diseqc 1.2
