Multiple Hauppauge USB2 transceivers

I have an IguanaIR USB transceiver that just went bad. I have it because
I have three tuners and Comcast has gone all digital in my area with the
Qam channels encrypted so I have three DTA's and the IguanaIR device can
blast up to four devices. So I am waiting to get a replacement one but
in the mean time I had to resort back to my MCEUSB2 transceiver.

So I have a question about the MCEUSB2 transceivers, I know they have
two blaster ports so I tried to use a splitter since I pulled apart the
cover and saw the jacks are stereo jacks inside. So I tried the stereo
to two mono splitter I use with the IguanaIR to see if it would let me
use three transmitters, two blasters in port one using the splitter and
the third blaster in port 2. When I try to do an "irsend
set_transmitters 3" it tells me that only two blasters are supported.

I am not sure if this is a driver limitation or a hardware limitation so
my first question is do they really only have two usable blaster ports?
My second question is can I use a second MCEUSB2 unit for a third
blaster port? If so how do you setup a second USB unit for blasting only?

There are really only two blaster ports.

Yes.

Set up a second lircd instance. Point irsend at the second instance's
lircd socket (eg /var/run/lirc/lircd1), port 1, for your 3rd blaster.

Re: Multiple Hauppauge USB2 transceivers [In reply to]

Thanks for the response Jarod. Ok I have the second lircd instance, by
typing:

lircd --driver=default --device=/dev/lirc1 --output=/var/run/lirc/lircd1 --pidfile=/var/run/lirc/lircd1.pid --listen

and I can see both lircd and lircd1 in the /var/run/lirc folder. How do I make the second one survive a reboot?

Then how do I point irsend to second instance? looks like I would use irsend -d lircd1 set_transmitters 1" then "irsend -d lircd1 send_once DTA 3 " ???

*Dora has no automated second instance start facilities, so you either
have to hack something into /etc/init.d/lirc or just start the second
instance via /etc/rc.local.

Yep, that looks about right. Though you can probably just omit the
set_transmitters bit until you actually have something connected to
the other port. It'll blast out both ports by default.
