Future request

Postby Jan Lichtenbelt » Tue Aug 20, 2019 3:26 pm

To connect my own PCB's to the EBlock2 programmer board BL0080, I would suggest an adapter from the 16 pins connector to a 15 pins SUB-D. In the 16 pins connector, there are 2 pins with GND. One of them can be deleted in de sub-D 15p.

I konw there is alreday an adpter to SUB-D 9 pins, but there the V+ is terrible missing.

Kind regards

Hi Jan,

We thought about using the 15-way D-type VGA connector for E-Blocks 2 but it ended up being a bit too large and bulky. Also we would hit the problem where customers see a VGA port and not an I/O port.

I may still have some 15-way prototypes kicking about, I'll have a dig around the office for you.

Hi Ben

That will be nice. I hope you will find it.

Kind regards

Jan

Hi Ben

I tried to find out which pins are there on the E-Block2 programmerboard BL0080 connector. The scheme shows:
Hart-flex f connections on programmerboard BL0060.jpg
Hart-flex f connections on programmerboard BL0060.jpg (68.65 KiB) Viewed 559 times


But, by means of resistance measurements, I found:
Harting connector on BL0080 programmer board.jpg
A0..A7 can be replced by B0..B7, etc
Harting connector on BL0080 programmer board.jpg (74.4 KiB) Viewed 559 times

The resistance is 27R, as expected. With A6 and A7 on depending on the oscillator switch. And in case of B6 and B7, they are not directly connected to the corresponsing pins of the microchip (but only indirectly by the central chip, if the power is on).

My question is, if this numbering is correct? And can you tell what the others pins 10,12,15 and 16 are?

Kind regards

Jan

Hi Jan,

In your pin numbering pin 10 is +V i.e. the voltage of the upstream MCU which is 5V or 3V3 or user selectable via a switch on the upstream board. We use this to convert incoming voltages so that they are correctly scaled to not damage the MCU.

The other pins are to do with the 10F auto ID chip on board every downstream board. Either to program the 10F device or to perform the auto ID.
