JD-ICE 2 sketch

Possible wiring to emulate a printer connection:
-- 
pin 1 (data strobe) ---> pin 10 (Ack)
pin 11(busy) , pin 12(paper end), pin 17(select inhibit) --> Ground
pin 13(select) --> pin 15(!error) --Tied together, but floating
-- 

ECP compliancy note: pin 16(reverse) is used to active
the LEC enable line, that must be NOTted for the input
or output LEC (bidirectionality bit).

for safety reasons, add a zener for voltage limitation (3.3V)
and one for the inverted polarity.

- possible LED
- 5 ICE output bits + 1 'POWER' bit
- the INPUT LEC buffer should have a fixed female connector
with GND&VCC to handle through an external circuitry (with
transistor) the device powering

suggested pinout:
pin 2, data 0 = ICEDI
pin 3, data 1 = ICECK
pin 4, data 2 = ICEEN-
pin 5, data 3 = ICERST-
pin 6, data 4 = POWER

ICEDO issues

It has been suggested (wiRe) to use a transistor to have a better ICEDO signal - needs verify --Legolas558 08:29, 4 July 2006 (CDT)

Actions ICE connector

WiRe said: Here is the portmap of the original ICE-Interface, you can also use this DB9 connector between JD-ICE and the ATJ chip if you want to be compatible to Actions original ICE Interface-Card:
