1. Find the serial port numbers from the Device Manager - devmgmt.msc. Should be COMxx where the xx is one or 2 numbers.
2. Batch file in the Startup folder with this:

Code:

C:\<path to miner>\cgminer.exe -S \\.\COMxx -S \\.\COMxx

3. cgminer.conf file in the same folder as cgminer.exe, in the following format:

Code:

{
"pools" : [
	{
		"url" : "http://pool.com:8332",
		"user" : "user",
		"pass" : "pass"
	},
	{
		"url" : "http://pool.com:8337",
		"user" : "user",
		"pass" : "pass"
	}
],
"api-port" : "4028",
"expiry" : "120",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"submit-stale" : true,
"temp-hysteresis" : "3",
"shares" : "0"
}

Some of those settings may not apply to you, but they are what work for me. Apparently there is a way to put the device info into the config file, but I have never been able to get it working that way. If the config file is named cgminer.conf, it will be loaded automatically without having to be specified.

working on this.....can i still run GPU's at the same time?

It looks like it is on Com3.....but I cannot get right.  What should the script look like?

C:\<path to miner>\cgminer.exe -S \\.\COM3 -S \\.\COM3

?

You would need to change the config to include the usual GPU info - unfortunately I don't have a GPU in the box that is running my Single, so I can't provide an example. But you should be able to blend the configs from a GPU machine with the one above and use both. If you have never used a cgminer config file before, there is an example included in the download to go off of.

C:\<path to miner>\cgminer.exe -S \\.\COM3 -S \\.\COM3

?

If you only have one, just remove the second -S \\.\COMxx entry, or add more if you have more than one. If the xx number is lower than 10, you can use it without \\.\ I think.

I got the one working....now I need to get the other 5 daisy chained.  Send me you payment address!   EDIT.....your sig address ok?

Siggy one works. Thanks.

Has anyone figured out the problems getting the config file to properly load pool details yet?

Has anyone figured out the problems getting the config file to properly load pool details yet?  

It's extremely sensitive to the tiniest error in the syntax. So if you have only one pool, there might be an extra comma somewhere. Or if you added another one, you might have one too many curly braces.

Dual pool example was posted initially, this should work for single pool (although I recommend a failover):

Code:

{
"pools" : [
	{
		"url" : "http://pool.com:8332",
		"user" : "user",
		"pass" : "pass"
	}
],
"api-port" : "4028",
"expiry" : "120",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"submit-stale" : true,
"temp-hysteresis" : "3",
"shares" : "0"
}

If that doesn't help, start the batch file from a cmd prompt and see if you can identify what error is making it unhappy.

EDIT: most of the values from the config file and the command line can be mix-'n-matched - so if you feel like specifying the pools on the command line, just remove the associated bits from the config file.

If you are having problems with the pools set up in the config, just delete them totally.  Fire up cgminer, enter the pool(s) info through the cgminer interface and save the config file.  Instant proper formatting.

This is how I did it with my 4 pool setup when I borked it up typing it into the config file.  I got tired looking for where I had a extra space, or missing a comma, or whatever the hell it was.  Granted, it was 4:30AM, and I had been, and was still drinking.


Why is it that it makes perfect sense to mess with perfectly working rigs at stupid early AM after drinking heavily?  "3:00AM, I'm wasted...  Let's see if I can switch this rig from Ubuntu 11.04 to Windows 7 Ultimate x64 even though it's been running rock solid for 2 months."


Note for invention idea:  Breathalyzer Door Lock to prevent drunk idiots from entering the rig room.
