NX 8E Serial Connector Pinout
NX-8E Serial (RS-232) Connector Pinout
NX-8E serial connector is a 10 pin IDC male connector on the alarm panel circuit board. It is easiest usually to use an adapter cable to convert this to a standard 9-pin (DE-9) RS-232 connector.
Pinout on the connector uses the so called "DTK/INTEL" PC motherboard pinout. So ready-made adapter cables are rather easy to find. WARNING! There is alternate pinout used on some PC motherboards (AT/EVEREX), ready made cables following this standard will not work, but are often easy to modify with little bit of soldering...

|Signal Name||IDC connector pin||Direction||DE-9 connector pin||Signal Name|
|N/C||1||1||DCD (not used)|
|N/C||2||6||DSR (not used)|
|N/C||7||4||DTR (not used)|
|N/C||8||9||RI (not used)|
When using standard motherboard ribbon cable with NX-8E, typically also a straight through serial cable (DE-9 female to DE-9 female) will be needed. Alternatively DE-9 (female to female) gender changer can be handy if planning on connecting USB to Serial adapter.
