[time-nuts] USB and Mouse conflict persists
Hello The Net: Since my motherboard died, I want to transfer the T'Bolt to another computer. I am running XP Pro with a USB laser mouse and a USB to serial adapter to the T'Bolt. The USB to serial adapter drivers are on hand and they loaded nicely, with the computer setting the USB port to COM10. System worked fine with Lady Heather on the original computer. I tried using the mod to theboot.ini file.I added: NoSerialMice:COM10 on the very first line. To date I still have a conflict with the mouse I can move the COM port assignment for the adapter, but I can not find what COM port the mouse is using. The mouse does use IRQ 12. USBView software does show which USB ports are used, but not the mouse COM port assignment. How do I fix (permanently assign) the Com port used for the mouse, so there is no conflict ?

Re: [time-nuts] USB and Mouse conflict persists
A USB device doesn't use a COM port. More likely it's an IRQ conflict between the devices. Try removing the COM port adapter, reboot, and then plug it back in to a different USB port. This should cause the computer do dynamically assign a non-conflicting IRQ address.

Hi Stan, I am running XP Pro with a USB laser mouse and a USB to serial adapter to the T'Bolt. The USB to serial adapter drivers are on hand and they loaded nicely, with the computer setting the USB port to COM10. if your adapter uses one of the popular FT232 chips from FTDI, then your mouse will be rediscovered from time to time, thanks for the Serial Enumerator feature present in the driver (see http://www.ftdichip.com/Documents/AppNotes/AN_107_AdvancedDriverOptions_AN_73.pdf ). To disable this incredibly frustrating function, open the windows device manager and remove the serial mouse. Then open the properties of the serial COM port. On the tab Port Settings click Advanced and in that window uncheck the box next to Serial Enumerator. http://lh5.ggpht.com/_zKkNaqX3vkM/S-mRNIaXuoI/Aw8/W6mWXYShUC8/s1600-h/serial-properties%5B2%5D.png You'll have to repeat this whenever your USB-to-serial adapter is re-discovered, for example when you've moved it to a different USB port on your machine.

Re: [time-nuts] USB and Mouse conflict persists
Stan and the list: This topic has come up a number of times, and I've been annoyed by the behavior as well. The solution I have found is to use a little utility called 'NoSerialMouse' that was created by Marcio Borges. It requires no installation, you can just run it as needed. You will be able to choose the com port(s) you wish to address. It's solved my problem on my Win7-64 box. Unfortunately, the author's website is apparently dead, so I have placed it on my website at http://www.pumpkinbrook.com/files/NoSerialMouse.zip . Although the file is clean, you guys don't know me from Adam, so use proper caution before running it (virus scan, etc.). Hope this helps. This is such a common problem, maybe this should be placed in the files area. 73s, Paul - K9MR On 5/11/2011 9:25 AM, Stan, W1LE wrote: Hello James, Is there some way to permanently assign an IRQ and to provide me some visibility on which IRQs are assigned and where ?

Stan; I had the same problem. The correct fix (i.e. permanent) is to buy a RS232C plug-in board for your PC. This allows the port choice to remain fixed.

[time-nuts] OT Interesting microwave assembly
Sorry for the Off Topic nature of this but things haven't been too on topic of late. Anyway, I digress. I stumbled across an interesting microwave assembly and I know there are some microwave nuts around here, I think some of our European friends. It has a Delphi (I could find no trace of them) DE127-02 Microwave source. I thought the output frequency was 12.7 GHz, but it can't be. Perhaps the reference is 12.7 MHz. This feeds into a Milliwave OS5PO amplifier which is labeled as 25.3 to 25.5 GHz. This feeds an assembly I assume is a mixer. The other input to this mixer? is from another little unlabeled block with power wires which feeds a waveguide isolator and filter. I am assuming these last two. The output feeds a Trak 60A3001 isolator which is listed as 2 to 4 GHz. So, this would appear to be a 25 to roughly 27 GHz downconverter. I have no way to test it, though I would love to. If anyone is interested or has info, please contact me off list. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
[time-nuts] Resolved: USB and Mouse conflict persists
Hello The Net: Thanks for all of the timely pointers. The problem with XP Pro has been resolved. My serial to USB adapter uses the Prolific chip. As indicated under device manager. After plugging in the T'bolt to the adapter and into a computer USB port, Device manager, under mice and other pointing devices showed an active Microsoft serial ballpoint As suggested I left clicked and DISABLED it vs. deinstalling it. Control over the mouse cursor returned to normal operation. Adding a external USB hub by itself, had no adverse effects. Adding a T'Bolt and adapter to the external hub had no adverse effects adding a second T'Bolt did have a problem. but the ballpoint device was then DISABLED. Adding a third T'Bolt to the external hub had no adverse effects. Adding a cheapie Bluetooth USB adapter had no adverse effects. Adding and pairing a Bluetooth mouse and keyboard had no adverse effects. Under device manager, USB ports, advanced, I changed the COM port assignment to COM10, 11, and 12. Lady Heather beta started up fine with their command line COM port assignments. The motherboard is an Intel D945GCLF2D with installed dual core Atom processor. (~80$) MicroATX. Total power draw is ~40 watts. Could be lowered a few watts even more, with a solid state hardrive. I only have 1 each PCI expansion slot and that is occupied by the M-Audio 4 channel 196 K sampled soundcard. Not the fastest CPU, but fast enough. and I have a DC power supply for it, to run off of +12VDC. I will go back into the boot.ini and delete the NoSerialMice entries. I will explore the /fastdetect:COMx command as well as the impact of not allowing plug and play accessories from the BIOS. That was last weekends project. Next project is to get the Agilent IO/drivers and their ARB waveform software working under serial control with a 33120A, option 001, that will use the T'Bolts 10 MHz as a reference. Thanks for all of the timely assistance. The pointers I got were a giant step ahead of what google found.

Will the new design also be based on a high-speed op amp, or have you come up with a different amplification/isolation design to achieve the better specs? Thanks for the TADD-[123], I've been pleased with all of them.

Will the new design also be based on a high-speed op amp, or have you come up with a different amplification/isolation design to achieve the better specs? It uses a completely different design with discrete components. Thanks for the TADD-[123], I've been pleased with all of them. You're welcome!

Re: [time-nuts] Distribution amp
Have a look at http://g4hup.com/DA/DA1_4.htm. These have been quite popular this year so far - maybe because the TAPR unit is temporarily unavailable? 73, Dave, G4HUP From: Bob Bownes bow...@gmail.com To: Discussion of precise time and frequency measurement time-nuts@febo.com Sent: Monday, 9 May, 2011 16:17:01 Subject: [time-nuts] Distribution amp I know it has come up in the past so I thought I would check here before hunting one down in the outside world. Anyone have a suitable distribution amplifier that they are looking to part with? My consumer device count has exceeded my source capability. :) Please respond offline, save a few electrons.

Re: [time-nuts] Antenna query
Bill: That appears to be one of the PCTEL/MAXRAD series antennas that Lucent has used for years for their cell site GPSDO equipment. Although they typically used the 26 dB gain version, rather than the 40 dB gain version you pointed to. They are available on eBay for as little as $20 very-used up to $90 new-surplus, including the mounting casting and rubber gasket. --- Graham / KE9H == On 5/11/2011 5:40 PM, William H.
