3.8 Connecting the Remote Display / Keypad Module
It is possible to control the programmer via a ‘Remote Display / Keypad Module’ . This module plugs
into the RS232-2 port on the programmer. An RJ11 cable wired 1-1 is used to connect the ISPnano
to the ‘Remote Display / Keypad Module’ . The RS232-2 port features both the RS232 signals and a
switched +5.2V supply to power the remote display.
The table below details the connections between the ISPnano and the ‘Remote Display / Keypad
Module’ .
