Dear OS9 users. I posted this once before, but didn't respond quickly enough to a generous response I received from one of you, and now the response has disappeared from my posts. I tried reposting, but that didn't seem to work, so here it:
I'm trying to run an older 4x5 digital scan back camera that is cabled to a mini computer called a Dicolite, tethered via SCSI cable (for imaging), and also via serial cable, via Keyspan Twin Serial adapter (for running diagnostic software only) to my G4, running OS9.2. This is the proper set up for the DicoLite mini computer. It's controller software works from the G4. I've never used this used camera system before, it's new to me, but it's what I want, and I've been on the phone, many times, and emailing continually with Mike, it's designer/engineer, a great guy. We've done extensive trouble shooting, but the G4 is not communicating with the DicoLite. Specifically, I had to first replace the Dicolite's hard drive, which I did no problem. Now it starts up and sounds good. But now I need to run the diagnostic software via the usb/serial adapter, emulating a modem port, in order to initialize the new hard drive. I'm using a Keyspan Twin serial adaptor, as per instructions. It USB plugs into the G4, and as two serial ports at the other end. The #2 port gets serial cabled directly to the Dicolite, which is the proper port for emulating a modem adaptor. I have set its permissions to operate that way, as per instructions, in the Keyspan Twin control panel on the G4. All cabling and hardware looks good. I also checked the serial wiring inside the Dicolite. The Keyspan twin is an older model # 28. Not the latest 28xg, or even the 28x. I can't find documentation on the 28 at all, but Tripplite, the company that now manages Keyspan products, believes it should work, if not broken. I got it seemingly new, in an unopened box, from ebay. I installed the driver Tripplite recommend. The driver is visible, and set up properly to emulate modem port in the control panel, as I said. I've tried to configure the G4 so it doesn't use another modem port for anything else, but this is confusing to me. I've turned off anything in the control panels, and extensions manager that seems modem related, except for the Keyspan of course. I even physically disconnected the G4's internal modem, but have been told that if there is a bit of logic that wants to use the internal modem it doesn't matter if it's unplugged, the logic may still ignore the keyspan. That's basically the symptom I'm experiencing. When I open diagnostic software on G4 to display a diagnostic window showing Dicolite/mini computer status, and Dicolite voltage, and then turn on the DicoLite, the Diagnostic window should immediately acknowledge to the Dicolite as "not ready". It does not. I've also tried it with the Dicolite powered on first, and then opening up the software. But the official way is software first, then Dicolite. Nothing works. I need the diagnostic software to recognize the Dicolite in order to begin initialization of the hard drive. It doesn't see the Dicolite at all. Also in the voltage window it says zero, indicating no communication, with the Dicolite, which is on and drawing power (I can hear the hd spinning, and see the fan going.)
Perhaps the Keyspan Twin is no good. This is the second Keyspan Twin I've tried. I thought the first one was broken, and threw it out. My engineer says it's seems like a G4/OS9 issue.
I do have a friend with an old Mac running OS7, which has serial ports, but that probably won't run the diagnostic software for testing.
I guess my first question is how do I insure nothing else is trying to use the modem? Probably more questions after that, but any thoughts will be appreciated very sincerely!
Thanks.
Nick
