First, is there a Pantel RS-232 command set in a version of the 232 Mega list? I have the first version of the list, but can't seem to find if a newer one exists. If there is a working Pantel command set, that solves my problem.

I am trying to create a Pantel command set. Setting the Hex button to "on", and typing in the string as they appear in the Pantel 232 document, I seem to get odd characters appearing in my string.

I enter as follows (with the hex button set):

EA 05 26 03 18

( 0xEA 0x05 0x26 0x03 0x18 in Pantel document, component video input )

and when I save it, it shows as:

\xEA\x05&\x03\x18

Why am I getting the ampersand in the string after the 05 and the 26 is gone?

If I type it in with the hex button unchecked (entered as \xEA\x05\x03\x18 ) it still shows up the same ( \xEA\x05&\x03\x18 ).

I would expect that it should look like:

\xEA\x05\x26\x03\x18

I have only to assume I'm missing a simple step here and just need to be pointed in the right direction. Done a lot of 232 on Pioneer, Epson, Yamaha and some others, this is my first Pantel. Also, their documentation only has a command string for one component video input, but the tv has two component inputs. Anybody know the string for the second? I'm hoping it's not a toggle command :o

So, any help appeciated, point out my failings and direct me toward the light :)

Thanks in advance to all.

This is an ASCII representation of the hex string which you entered. The "\x" character sequence is an escape sequence which indicates that the 2 characters immediately following the "\x" are a hexadecimal value. This escape sequence is used to represent ASCII character codes which do not correspond to displayable (human-readable) characters.

The reason you are getting the ampersand is that it is the ASCII character which corresponds to the hex value 26 which you entered when you typed in the hex string. All of the other hex values you entered do not correspond to a displayable ASCII character, so the "\x" convention is used to represent the hex value.

Here's a table which shows the standard ASCII character set with decimal and hex codes for each character:

Snarfshark, thanks for the reply.

So, would it be your thought that what is showing up in the RTI library should be a working string, even with the odd characters? Taking a look at the ascii table makes a bit more sense out of some of the things. I hadn't tried them yet, as it appeared something was wrong with them.

Hate to beg, but anyone have a known working Pantel 232 file?

Yes I would think the string as you entered it would work. If you haven't actually tried it with the TV I would try it.

Just remember that even if the command string is correct, that there are other variables which can cause it to not work. Getting the correct RS232 Cabling and baud rate etc will also be necessary.

Joe Pantel (CEO of Pantel) posts occasionally on the Custom Installers Lounge forum here at RC. I believe that his user name is Jpantel - he has been really helpful in the past. You might try looking up his profile and emailing him.

here you go check hex and paste it in
115200/n/8/1

make sure you also deal with pantels jacked up rs232 pinout

power on
0F 00 F9 0F E0 01 00 00 00 00 00 00 00 00 00 00 80 FF

power off
0E A0 05 02 70 01 00 00 17

component
0E A0 05 02 60 03 00 00 18

I don't use Pantel but I have heard pretty much only good things about them.

But in my 25+ years of dealing with RS-232, I can't say I've ever seen someone use pin 1 for ground, 3 for RX & 4 for TX. That is strange.

But then I realised that if you happen to have read the pin numbers in reverse on the top row, they are correct. So I'm guessing someone messed up during the engineering / manufacturing process.

Do Pantel at least have a sku for an adaptor?

However it is well documented in their RS-232 document so hopefully it doesn't catch out too many people. And the protocol seems very comprehensive.

A follow up to the Pantel Dilemma.

After being assured and reassured (even by the CEO in the above post) that the RS232 documentation on the Pantel site was in fact correct, I received an e-mail last week with new Pantel RS232 documentation. The command strings are completely different than the document still currently available on the website, and the new pinouts are a standard 2/3/5. New commands in a new library file, a straight through wiring configuration, and presto, it works. The downside is that we have had a customer with a $5,000 TV that has been basically useless for the past month.

The existing (and still "current") documentation shows the TV having a male 9 pin connector, using pins 1,3,4, and I was told that the female connector on our new TV would wire the same way. The new documentation shows the TV having a female connector, which it in fact does.

I have about eight or more hours into trying to troubleshoot the RS232 issues with this TV, with no resolution until the e-mail arrived. My question would be, if you are changing a product, and ship the product, should somebody not know that the changes have a possible impact on the usefulness of the product? Given the current economic climate, and the general competitive environment of the CE world (yes, I realize this is a niche product), I view this as a pretty sizeable risk to assume.

Anyway, for those interested, here are a couple of the working strings (entered into the library manager with the hex button checked):

38,400; 8, N, 1

Power Off
69 D0 00 00

Power On
69 D1 00 00

Again, thanks to those who tried to help.
