3.4 Optional captive cable connection - RS232 and USB

The PCB has a special connector  J1  (an 8 pin, 2mm pitch header connector) which can be 

used to attach a captive cable with a matching crimp housing, for RS232 or an alternate 

USB connection.

The standard connector fitted to the PCB, in most cases, is a Hirose DF11CZ-8DP-2V male 

header plug with shroud. The matching crimp housing is the Hirose DF11-8DS-2C.

CAUTION:

 If the J1 connector on your PCB does not include a shroud, to guide the 

matching wires into place, you can use a wider range of mating connectors. Do please take 

extra care to ensure your connecting cable is oriented correctly to match the pins.

CAUTION:

 There are a small number of VTAP50 v1 Rev 1 units in circulation. Please be 

aware that the pins on v1 Rev 1 hardware are pairwise switched.
