DirecTV D10-300 Serial Interface
|
|
Hi,
Apologies if this post is boring and outdated. Most of my searches on
this topic have yielded posts that are more than 2 or 3 years old.
Anyhow, I've been trying to get an old D10-300 satellite receiver to
interface with a new install of MythTv. I've followed the
instructions posted in the following:
http://www.pdp8.net/directv/directv.shtml
http://mythtv.org/pipermail/mythtv-users/2005-October/107586.html
That is,
1. I've bought and installed the serial-to-low-rate cable from
http://www.dtvcontrol.com/index.aspx?content=cable.
2. I've performed the reset on the satellite box to get the updated software
3. And, tried calling directv.pl at the command line with a number of options
So, for instance:
blaine[at]blaine-desktop:/usr/local/bin$ directv.pl box_type D10-100
verbose version
Version 1.7
blaine[at]blaine-desktop:/usr/local/bin$ directv.pl box_type D10-100
verbose get_channel
SEND: 0xFA [�] 0x87 [�]
RECV: Timeout Error
SEND: 0xFA [�] 0x87 [�]
RECV: Timeout Error
SEND: 0xFA [�] 0x87 [�]
RECV: Timeout Error
SEND: 0xFA [�] 0x87 [�]
RECV: Timeout Error
Error excessive retries
blaine[at]blaine-desktop:/usr/local/bin$ directv.pl box_type D10-100 port
/dev/ttyS1 verbose get_channel
yields the exact same output. One post I read offered the possibility
that there is some conflict on the serial port and suggested using
lsof to see. Came up null:
blaine[at]blaine-desktop:/usr/local/bin$ lsof | grep /dev/ttyS0
blaine[at]blaine-desktop:/usr/local/bin$ lsof | grep /dev/ttyS1
Another post suggested using statserial to check out serial ports. I
did this, but don't understand the output:
Device: /dev/ttyS1
Signal Pin Pin Direction Status Full
Name (25) (9) (computer) Name
----- --- --- --------- ------ -----
FG 1 - - - Frame Ground
TxD 2 3 out - Transmit Data
RxD 3 2 in - Receive Data
RTS 4 7 out 1 Request To Send
CTS 5 8 in 0 Clear To Send
DSR 6 6 in 0 Data Set Ready
GND 7 5 - - Signal Ground
DCD 8 1 in 0 Data Carrier Detect
DTR 20 4 out 1 Data Terminal Ready
RI 22 9 in 0 Ring Indicator
Yet another post suggested that the excessive retries error message is
associated with faulty cable. It seems like alot of folks were making
these cables themselves, but I bought mine. What are the chances it's
defective?
Should I give up on the D10-300 receiver? Is there equipment
(satellite - directv) that is easier to interface with? Is the reason
I haven't been able to find any more recent posts on this topic b/c
people have moved on to newer gear?
Any help, guidance, ideas will be greatly appreciated. I've spent so
much time trying to get this working.
- Blaine
