BAMA has the manual for download. ftp://bama.sbc.edu/downloads/tek/2445/ I didn't see your problem in a quick skim of the troubleshooting section, but you might be able to get more info from the diagnostics. |

Perhaps a stuck front panel switch or button. That's one of the startup tests. the lit front panel lights make up a trouble code that is described in the Maintenance Section. BAMA has the manual for download. ftp://bama.sbc.edu/downloads/tek/2445/ I didn't see your problem in a quick skim of the troubleshooting section, but you might be able to get more info from the diagnostics. BAMA now wants a password to download,but their mirror site doesn't. BTW,the Dallas NVRAM IC is right at the 10 yr age limit in the IC data sheets,so loss of calibration data is possible. -- Jim Yanik jyanik at kua.net |

However, the error message when I hit cancel results in: 530 The maximum number of anonymous FTP users (10) are already connected... try back in a few minutes. I can't tell if this is an intentional new policy or a misconfigured ftp server. I'll guess(tm) the latter. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Not a configuration error, the site wishes to limit the max number of users, that's all! g The mirror site(s) don't seem to be as limited, try them. |

I've used the original BAMA site a few times over the years and have never seen the user limit message, until yesterday. Luck and my perfect timing as usual. Thanks. I downloaded a 2465B manual a few weeks ago from BAMA,had no problem,then the other day I got the password crap.The mirror site worked fine. -- Jim Yanik jyanik at kua.net |

Like "Fail Test 04-11" on the Readout line? or no display at all? Verify that the unit is not in single shot mode. Jon it's going into startup diagnostic test,then stops. could be a stuck front panel button or switch,or a hardware problem.(on the A5 microprocessor board.)Probably a hardware problem. the front panel LEDs light to give a preliminary error code. the manual Maintenance Section(Sec.6) has the info for this. -- Jim Yanik jyanik at kua.net |

I'll bet you were using Internet Explorer. IE has trouble with FTP access on some servers and has been reported multiple times for the main BAMA site. -- And another motherboard bites the dust! |
