2.7 Standalone Remote I/O Programmer Control
2.7.1 Overview
The ISPnano programmer can be controlled using a simple 4-wire Remote I/O (TTL) signalling
protocol as shown in the diagram below. This control method is ideal for interfacing the programmer
to In-Circuit Testers (ICT’s) or other production equipment which does not have an RS-232 port.

The Remote System simply asserts the programmer
<START>
signal to initiate the execution of a
‘Programming Project’. The programmer will then assert the
<ACTIVE>
signal to indicate that it has
commenced programming. At the end of the Programming operation the programmer asserts either
the
<OK>
or
<FAIL>
signal depending on the outcome. The Remote System must then de-assert the
<Start>
signal to allow the programmer to reset ready to program the next device.
Please refer to section 2.8.3 for an example of the Remote I/O control signal waveforms for a typical
programming iteration.
