If you use a null modem cable, it has a transmit/receive crossover built in (which you want) if you use a gender adapter then you will have to achieve the crossover some other way: the NX-584 has jumpers on it to flip the transmit and receive pins.Ī powered USB hub.

Both of the above two devices have male connectors, so one of these is required to make the physical connection. If you are paranoid, bring two, with different chipsets.Ī null modem cable, or a female-female DB9 gender adapter. Some users swear that the chipset matters too, but Vera should be able to handle Prolific, FTDI or Silicon Labs chipsets without issue. You can buy the official P-0003 cable, or you can make your own.Ī USB-to-RS-232 adapter, with a USB-type-A plug on one end and a male DB9 plug on the other. If you use the NX-8E, a ten-pin-to-DB9 serial cable, for changing the silly 2x5 serial jumper on the board into a normal serial port shape. If you have an NX-8E with an on-board serial port, this cable is unnecessary. This is exactly the same stuff as you use to connect wired keypads to the panel.

If you use the NX-584, four-conductor cable, for connecting the NX-584 to the main panel. If your friend has a bare NX-8, or a different model of main board like the NX-4 or NX-6, none of those have a serial port and you will have to connect an NX-584. The NX-8E is an enhanced version of the NX-8 which contains (among other things) a serial port. That “E” is important the NX-8 has no serial port by itself.
