3.3 Mounting points

The PCB has 2.7mm diameter mounting holes for fixing the unit. Either use the 50mm spaced holes

on the snap-off tabs, or remove those tabs and make use of the three holes on the body of the

board. Use 2-4 small nuts and bolts.

The user's smartphone should be able to tap within 10mm of the antenna on the PCB. The antenna

position should be clearly marked and easily accessed, so that users can position their smartphone

appropriately.

3.4 RS232 connection

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 crimped cable-end plug.

The standard connector fitted to the PCB is a Hirose DF11-8DP-2DS male header plug with shroud.

The matching socket is the DF11-8DS-2C.
