Looking for connector information

[llandyw]

Not sure if this is the right forum, but I didn't see anything else that might do.

I have an adapter box that claims to convert an NI 68 pin connector to a different connection.  It contains only a single buffer chip.

Pin/signal names are as follows.

1/VCC (+5V)

2 connected to 3

5 connected to 6

9 connected to 13

10/*SWSTRB

11/GND

12/FAILSAFE

16/SDATA (input to buffer)

17/no name, but assuming Read/Write since it enables buffer

23/SDATA (output from buffer and connected serial device

24/GND

39/GND

44/*SRSTRB

45/SCLK

46/GND

50/GND

SDATA is a bi-directional line.  This box is connected to another device to program memory in the device.

I am hoping to find data on the connections themselves as well as any information on this programming method (timing and use of SWSTB and SRSTB.

Hi Andy,

Could you clarify what Box you are using? Name? Product number?

What is the end goal of your application? From my understanding you are using the NI SHC68-68-EPM cable to connect to your breakout box. What do you aim to achieve with your breakout box?

[llandyw]

I do not have a specific number, at least not an NI number for the box.  All I have is the contents.

The schematic is contained in the attached PDF.  At this time I have no other information.

There is a manufactor noted on the sheet 🙂

However , lets see:

1. Your dock tells us it's a programming interface

2. 68 pin connector with +5V on pin 1 . No analog card, a digital IO card like the 6601 could fit. BTW to what type of card is this adaptor connected?

3. assuming a 6601.. pin 1,17 NC, OK, lets try 6602:  jumper pin 2-3, 5-6, 9-13  migth be a hardwired identifier to PFI I/O,  all others reach Digital IO lines..

So you have a programming adaptor for a device. What device??? You should know 😉

So if you don't know to what card it is usually connected, and you don't have the software (source code) : A useless hardware 

If you have a DIO card that match and you know the protcoll of the memory, you can start programming 🙂

This is to program an EEPROM through a CPLD (cy37512P208).

Pin 1 being the 5V supply on this adapter is what's confusing since it's listed on the other 68 pin connectors as a frequency (I'm assuming a clock of some kind).

Again: Do you know to what kind of NI-Hardware this cable was connected? 

A PCI/PXI 6602  migth fit, PIN 1 is +5V, and the other pins just could be routed

[llandyw]

No, I don't know what NI device it is connected to.

What I do know is that it's connected to a laptop through this box and probably another adapter of some sort on the laptop itself.

I know we have one laptop with an RS422 adapter on it, but this one is different and I do not currently have physical access to it.  Although I have instructions on using the other one, it doesn't go into detail other than the specified name of the system which is totally meaningless as nothing is descriptive about the name.  Even if there was a descriptive name I doubt it would mention what the connection coming out of the laptop to this device is called.

Found the manual for the 6602.

This does appear to be the card I was looking for.  Thanks for your help.

Happy reverse engineering 😄
