4.7 J6(c) - Equinox 10-way Header (UART Boot Loader)
This connection method is suitable for interfacing the EPSILON5 programmer to a Target System
which features the following:
To implement this connection, simply plug the 10-way ISP cable into the EPSILON5 J6 header and
plug the other end of the cable into the matching header on the Target System.
Please note:
The programmer interfaces to the Target System at TTL voltage levels. If the serial port to your Target
System is RS-232, you will need to convert the TTL levels from the programmer to RS-232 using an
external convertor.

Description
This pin should be connected to the Target
System Vcc. This voltage could be used to
power the programmer depending on the
settings of the power switch/jumper on the
programmer.
Not connected
PSEN pin
This pin is driven LOW by the programmer
to enter ‘Boot Loader’ programming mode.
Programmer RXD (Transmit) pin
The programmer transmits serial data on
this pin to the Target Device RXD
(Receive) pin.
