I don't have the pin out for the ECCO but it may be the same as the Remex RR-7300 paper tape reader. The Remex has a 25-pin D-type male connector mounted on its interface board. The pin out is: 1 - Data track 1 (out) 14 - System ready (out) active low 2 - Data track 2 (out) 15 - External Inhibit (in) active low 3 - Data track 3 (out) 16 - Drive Right (in) active low 4 - Data track 4 (out) 17 - Drive Left (in) active low 5 - Data track 5 (out) 18 - High Speed (in) active low 6 - Data track 6 (out) 19 - not used 7 - Data track 7 (out) 20 - not used 8 - Data track 8 (out) 21 - not used 9 - Data Ready (out) 22 - not used 10 - Mode Select (in) 23 - +5 Vdc 11 - Signal Ground 24 - Signal Ground 12 - Signal Ground 25 - Chassis Ground 13 - Signal Ground Model Select HIGH, Data Track 1-8 and Data Ready asserted is LOW. Model Select LOW, Data Track 1-8 and Data Ready asserted is HIGH. Drive signal should remain asserted until Data Ready is negated. To stop on character the drive signal must be negated within 0.750 milliseconds of Data Ready being asserted. ----- Original Message ----- From: "James Willing" <jimw(a)agora.rdrop.com> To: <classiccmp(a)classiccmp.org> Sent: Thursday, January 02, 2003 7:49 PM Subject: Pinout for EECO Tape Reader?
