Hey All,

Has anyone ever managed to find out if the Scientific Atlanta 8300HD cable box has descrete Power On / Power Off codes.

I have looked everywhere and nothing.....

I even looked at changing out the box for the Comcast Motorola cable box which has descrete codes but the Motorola box wont work in South Florida..

Any Ideas other than leaving the box on all the time.

Thanks TF.

you could always go with a current sensor/voltage sensor setup and just use the toggle command as a last resort

There may be discretes...sort of. Go into the settings and see if there is an option called "Power On Keys". Select the option for this "Power and Numeric". This will allow you to power up the box with a 0(zero) which won't change channels, and 0(zero) delay 2 sec, power which will turn it off.

Not all models have this software but it's certainly worth a try.

This all depends on the firmware you're running (and I don't even mean SARA vs Passport vs OpenCable)...

My local cable company runs SARA and has the "Power and Numeric" option, but they also have it set to tune the next available channel whenever an invalid one is entered. So enter channel "0" which doesn't exist, and get channel "1". They also have power saving enabled on the hard drives, which means you cannot come up with a single startup macro that doesn't end up changing channels, since the delay for the hard drive to spin up is greater than the command timeout when the hard drive is already on, so a [0], [Delay], [Exit] macro for power on doesn't work quite right either.

And of course you can't even leave them on. The cable company has several automatic power-down events each night... 1:15 AM and another after about 4 more hours. If they don't power down, the program guide doesn't update.

Best solution: voltage sensing. Serously, it's like a breath of fresh air for anyone who has tried to live with flaky automation of SA boxes.

I leave my SA on all the time. Regarding the "power-down events", I schedule the box to turn on every day in the morning (this command function should be in the menu). I donít think the box takes much juice and I donít care if it breaks because the cable co will just give me a new one. This set up works well for me.

My worst nightmare - an insomniac un-friendly cable box! :)

Well, at least it warns you that it's about to shut off and to press a key to stop it. :-)

Interestingly when it turns off this way it doesn't *really* turn off - the front display stays on, and you still get sound along with a grey screen with a moving "press any key to watch TV" message. Although it does stop timeshifting and shuts the hard drive off.

After turning on the option Power/numeric keys to get the device to come on.

send 0
delay 1000ms
send last channel
