i have done several h20s with 232 it is truly awsome control, no emitters, PIA doing your channel macros (come on RTI serial command library asap) any way every once in a while, 2 times in six months, i have a customer call and tell me his buttons are double hitting, press any button presses twice. it does not do it with factory remote or if you use ir from rp6. i have him reset power to rack via monster power 5100 on off button and it has worked both times.

today i finished a job with two h 20s on different rp6s that did it regularly. it is not every button press but every other two or three. this time nothing seems to work. i reset power reloaded config, etc.

has anybody dealt with this problem. does anybody have any suggestions on delay between characters etc. i do not have sustain checked.

i am using a page i wrote for my t2c and copying and pasting buttons to other projects, have done this several times back and forth etc. lots of writing and rewriting and trading between projects. does this make the files more prone to corruption or other problems?

RTI's serial command library?

Did I miss something?

-Chris

What's he's saying is "RTI, WTF, where is the serial command library we should have had a year ago with teh XP8"

Easy there fellas, we dont want to conjour up the anti RTI spirits

The XP-8 will be here soon, wouldnt you rather have it working 100% rather than 80% and be an in field beta tester??

It getting close from what I hear

If you want a 232 library, create on for yourself in an excel format and do a copy/paste as you need them, if we all had some spreadsheets we could then share with each other and eventually submit them to RTI to further advance the library or we could create a Mega 232 list??

If you are using 232 you should already be doing just this!

I would be happy to establish a format standard or template to start a 232 code list. I already use a simple format for most codes and have built auto code generartors when check sums are required. I would just need to get it posted for download.
If anyone is interested in this idea contact me via email and we can discuss the best way to get a database started. I am sure many of us have much to offer and much to gain from others.

You guys know how we have the mega code list...

How about the MEGA RP6 Serial List...

We take all the RS232 strings we have and put them on the RP6 as system macros. You would have to use some clever cut and pastes but I think we could have a file with just an rp-6 just chock full of all the RS232 commands.
System macros
Denon VOL+
Denon VOL -
.etc
.etc
.etc
Directv 1
Directv 2
Directv 3

Reasonable idea?

It has been awhile since I have looked at the protocol, but isn't $A6 the open channel command? You should be able to do your entire "Channel Macro" in a single command.
Examples:
Channel 276 = $FA $A6 $01 $14 $FF $FF $0D
Channel 78 = $FA $A6 $00 $4E $FF $FF $0D
Channel 11-1 = $FA $A6 $00 $0B $00 $01 $0D

Also, regarding your solution of resetting power fixing the problem, have you ever tried using the reboot command ($FA $96 $0D) instead of power cycling the rack?

That way you could have the homeowner press and hold the source select button for "His Sat" when the problem starts and it will reboot the box.

Editted to include examples.

I think you should look at the "Merge Pages" command in the file menu. It makes it quite a bit faster to use template files than copy and paste.

Where exactally are you guys finding the RS232 protocol docs?

I either got it in an email from a friend or a CD from the DirecTV booth at CEDIA; I can't remember which.

In general I get protocols from industry contacts I have, calling and bugging the tech support and engineers at the manufacturer, manufacturer reps that know I keep confidential things confidential, or sometimes they are packaged with the AMX modules.

I guess you just have to know people and be in the right places at the right times.

thanks for the tips 8. i will look into the $A6 command if it works i owe you one

edizzle,
What USB to 232 adapter are you using for the H20?

I always use this
[Link: iogear.com]

DirecTV lists these:

IOGEAR GUC232A
ATEN UC-232A
BAFO BF-810

Has anyone had problems with the H20 serial port since the mid-August update? I have a system with an H20 and an HR20 both controlled from the RP6 via serial which was working fine until the most recent update for the H20. Tried swapping out the box for a new one, which worked until the new box downloaded the update. Funny enough, the HR20 also had an update recently and it still works fine. I am crossing my fingers that DTV just changed the baud rate or something and the port has not been disabled. It is still getting power, which I can tell by the status light on the USB to serial flashing during a command. Anyone else experience this???

P.S. It probably goes without saying, buy DTV tech support has been no help on this particular issue, claiming that the serial port was never active in the first place.
