USB to CAN D-Sub Pins Backwards?

1

I soldered wires to the D-sub connector that came with the USB to CAN interface, following the diagram in the manual that’s on the product page. For the heck of it, I decided to include the +5v and GRND wires on the connector at pins 1 and 6. But when I connected the module to USB and tried probing the +5v and GRND wires, I got -4.8v. Checked to make sure my probe wires weren’t reversed, but they’re correct. Checked to make sure I didn’t reverse the pins at the connector, but they’re correct as well. Tried probing the +5v and GRND pins directly on the box, and still got -4.8v. It looks like the diagram in the manual and the physical box have different pin layouts. The manual says pin 1 should be +5v and pin 6 should be GRND.

Does that mean the CAN low and CAN high pins are wrong in the diagram, too? Currently I have CAN low soldered to pin 2 and CAN high to pin 7

The picture in the manual shows the front view of the device’s socket.
Not the connector.

Pin numbers are also visible on the plastic inserts in the socket and connector.
If you take the USBtoCAN and look at the socket, pin 1 is top left.

Ah, yes, thank you. I took a macro photo of the DB9 connector and I can now make out those markings.

Would be helpful if the manual specifically mentioned that the diagram is of the connector at the device, since the most recent reference immediately before the diagram is “Solder the CAN low wire to pin 2 of the DB9 connector.” and the diagram is only labeled “Front view”, not “Front view of the connector on the CAN to USB box”
