Re: [App_rpt-users] Beagle Board-xM + LOX OS and power consumption
Can't help you there. Don't know but I bet the RTCM is pretty low current draw. -- Tim :wq On Dec 24, 2011, at 8:27 PM, Ron Morell wrote:
Tim, OK, good to know. Now that the new firmware has the "fail over" to become a simple controller, is the CTCSS still generated in that mode with the new firmware? This device is so new, it is hard to understand just what to expect from it. WB6NIL rewrote the firmware for it very quickly, so it is definitely a moving target, but seems to be improving with each iteration.
What do you know about the power consumption of the RTCM and the Beagle Board + LOX computer. Thinking through the opportunity, I need a power budget for them. 73 and Merry Christmas! Ron KA7U

The no CTCSS generation statement is referring to when the RTCM is connection failure mode. Otherwise it will generate CTCSS. -- Tim :wq

Tim, Thank your for your reply and input. I am confused about the PL tone claim though. Check out this excerpt from a WB6NIL post:

The new version (0.60) of the RTCM/Voter board firmware now supports the following:
Notification via CW of host connection failure (with the option of repeating it periodically if still failed, along with option of repeating it after receiver un-key).
Notification via CW of host connection restoral after failure.
"Offline" repeat mode, where it becomes a "dumb" repeater if host connection is lost. Includes settable hang time. The "Notification via CW of host connection failure" feature also can serve as a CW identifier in this mode (and was designed to do so).
The CW speed, CW strings (content of messages), and some other stuff is user-settable from a menu.
Speaking of menus, the "big humongous" main menu is now split in to 3 nice, smaller ones. The 2 sub-menus are IP (networking) parameters, and "Offline Mode" parameters.
The only thing it does *NOT* do is generate CTCSS tone when transmitting. I doubt it ever will, since we are pretty much out of code space in the processor. This would require the use of floating point trig functions to calculate generation constants (or from a table), neither of which we have room for.
The 0.60 version will be available on SVN at 2115 PST tonight.
JIM WB6NIL As you have just read, Jim says there is no room on the RTCM processor to handle CTCSS. So are you sure that the RTCM does handle PL tones? I would have thought the tone generation would have been the same type of process. Ron - KA7U

Trying to catch up on the threads of information and now trying to understand the Beagle Board and LOX. So reading along, I find this board is using an ARM DM3730CBP 1GHz processor in the current versions. I find that Pickle Linux is supplying an Asterisk+app_rpt ISO image meant to be written to a 4Gbyte mini SD Card, and that GMK Engineering is selling a LOX board with adapter cables to connect it to the Beagle Board-xM and that this device will connect up to 2 radios.
Reading on, there is the RTCM device that is capable of replacing an Asterisk+app_rpt computer at a radio site, but these devices need to connect to a "Hub" Asterisk+app_rpt to be addressable through the AllStar Link Network. Recently WB6NIL has added firmware updates to manage these RTCM devices as a simple repeater controller in the event they lose connection with the "Hub" Asterisk+app_rpt switch controller.
So my questions so far are: how much power in watts does the Beagle Board-xM with LOX use on average? how much power in watts does the RTCM use on average? Has anyone compiled a Debian OS with Asterisk+app_rpt for use on the Beagle Board-xM, or is Pickle Linux the only currently available OS solution? Is the current Beagle Board-xM the recommended computer to use, or is another version better supported? Do the Beagle Board users need to have a JTAG device to debug and interface with the system and upgrade uBoot? If so, which JTAG device is recommended?
OK, enough with the questions. Given that the RTCM seems to be an attractive solution and the Beagle Boards are supporting up to 2 radios per device with a very elegant solution, I would like to learn as much as I can about these devices and their intended as well as extended uses. I'm not at all competent with the discussion on simulcasting repeaters and nodes, but from what I've read that is not really the scope of these devices, or is there something about simulcast that I've missed in the threads here?

If you read the information on the DMK and Miro-Node websites, the documentation says that the BeagleBoard-xM/LOX combo draws approx 500ma (although we measured it at aboud 375ma as I recall), and the RTCM draws 80ma (both at 12V).

I have set up a Beagle Board and DMK LOX interface I have put an entry in the Router for the port used I can get the WebTrancever to connect but not operate the PTT on the LOX If I go into the asterisk -r CLI and enter "beagle key" the PTT output activtes and of course "beagle unkey" drops PTT Can anyone confirm or suggest what I am doing wrong Bob VK6ZGN Perth, Western Australia
Try rpt stats and rpt showvars, see if you're "timed out" and/or what the COS/CTCSS status is.
