KeySpan Setup

[Arnie Schlissel]

And you’re keyspan adapter is connected to what? This is an FCP forum, so I’ll assume you’re using FCP. what version? What capture card? What port on the mac is it connected to? Are you using the latest driver from Keyspan that’s recommended for your version of Mac OS & FCP?

And perhaps most important, are you sure your S-VHS uses RS-422, and not RS-232?

Latest drivers and versions on everything. The keyspan uses a USb port and yes I am using FCP. My deck uses 422

[Thaxter Clavemarlton]

Is the deck in REMOTE?

Do you have the “control” setting in FCP set correctly?

[Ian Liuzzi-fedun]

yes and yes, I have a no communication error

[Ian Liuzzi-fedun]

Sorry I was kind of vague in the last post. Yes I have the settings right adn yes the deck is in remote. The error I am getting is no communication

[Christopher Wright]

You first have to make sure the USB device is enabled in Apple System serial device preferences, and then you have to go into the system setups in FCP and manually select the Keyspan for device control.

the keyspan serial assistant recognizes it and I have set it up manually – maybe it is my cable that converts mini sub 8 to 9pin

If this setup hasn’t worked before, you might have the wrong cable. There are many mini-din 8 to DB9 cables for printers, but they don’t work for deck control since they are pinned for RS232.

Addenda has a mac to rs422 cable listed here if you want to buy one. I had to make one in an emergency once, and it’s way easier to buy one:

Here’s the mac mini din 8 to rs422 9pin breakdown:

GND mac pin 4 rs422 pin 4 AND 6 RX Gnd, TX Gnd
RXD- mac pin 5 rs422 pin 2 TX-
TXD+ mac pin 6 rs422 pin 3 RX+
RXD+ mac pin 8 rs422 pin 7 TX+

thanks. Sorry, I don’t read the ending stuff with all those pin to pin stuff – I have never made more than a coax cable. Anyway – I am returning my cable and going for a different one and I will let you know
