Attn: those of you with A-Card SCSI>IDE

[Paul_s]

Jumper settings...


JP1 = IDE1
JP4 = Terminator Power ? (should that be on or off?)
JP2 = Terminator ? (should that be enabled or disabled?)

I'll be taking the onboard molex power and using it on the A-Cards power supply input.... does it need it though with such a low power device like a CF card?

Many thanks!

Hi Paul,

Don't go away. I can help you with this. I'm just digging out the manual for my ACARD SCSIDE bridge. I'll be back shortly...

[prowler]

OK Paul,

Before we start, here is a pic of my ACARD AEC-7720 SCSIDE bridge adapter.



There are three jumpers shown at the bottom left (JP1). These are the SCSI ID jumpers. JP4 is just to the left of the floppy-drive-type power input socket and this is the Termination Power jumper. JP2 is just to the left of the 50-pin SCSI connector and is the Terminator Enable/Disable jumper.

I'm a little confused by your reference to "JP1 = IDE1" above, and your mention of power supply inputs. Could you elaborate, please?

Ah mis-type there! I meant ID1 Mine's exactly the same as yours

The power supply inputs - referring to the floppy type power connector... do those need to be hooked up? If so, do the pins correspond to 'standard' floppy power connector type wiring?

Thanks

Thanks for your quick reply, Paul, and if yours is the same as mine then that makes things very easy indeed.

First, the power supply connector on the AEC-7720U pcb will take a standard floppy drive power connector from your PSU, and second, the CF card adapter you are using will require a separate supply or it will not be detected on the IDE bus.

Do you have the user's manual that comes with the AEC-7720U?

If not, I'll talk you through the configuration now and supply you with a copy of mine when I have time to scan it.

[Paul_s]

Nope, I never got sent a manual with mine so a talk through would be great!

I have a 3.5" IDE > 2.5" convertor coming off the A-Card which then goes to the CF adapter - on the convertor it has its own power input line so that's sorted

Thanks again

• JP1 - SCSI ID Switch connector (3 Jumpers)
• JP2 - Terminator Enable / Disable
• JP3 - Activity LED
• JP4 – Terminator power supply switch, default is ON.

OK Paul, quick talk through:

JP1 - SCSI ID:
This consists of a block of three jumpers which can be used to set the ID number the SCSI device (in this case the CF card via the adapters) will present to the SCSI controller. The number is in the range 0-7 and the jumpers have values 4, 2 and 1 counting from the left on the above picture.

I'm going to have to post this info in several parts to prevent being logged-off and losing it. So if this is OK so far, just give a quick reply to say yes or ask a question if you have one instead...

when using the 7720UW adapter with my csppc, I have the power plugged and termination enabled.

that's great. Thanks too Alex for the manual - some bedtime reading will ensue

I think everything is answered but if you want to continue with the notes prowler do feel free as I'm sure it'll help others who have this card

[prowler]

Well, I guess my help won't be needed any more here.

But you might just care to have a look at these related threads:

Well, Paul, looks like we posted at the same time! But I think a glance at the above threads should suffice.
