- ***** MODIFICATIONS
- To use a 5600 as a slave device it has to somewhat modified.
- This has to be done on a 5600 (art no 16144 R2) to automatically set it to parallel port boot mode:
- 1)
- Close to the LPT1 connector there are two resistors, between the "Pulse" inductor and
- the LS245. The one closest to the LS245 is a 4k7 pull up (R105). Remove it.
- 2)
- Between the other "Pulse" inductor and Etrax there is a black 5-pin inverter
- (D15). Short connectors 2 and 3 with a solder blob.
- ***** PINOUT
- To use this driver use cables connected like this:
- DSUB25-Male DSUB25Male
- 1 10
- 2-9 2-9
- 10 1
- 11 14
- 12 18
- 13 NC
- 14 11
- 15 NC
- 16 NC
- 17 NC
- 18 12
- 19 NC
- 20-25 20-25
- Thus the cables are symmetrical with most cables straight through,
- some crossed (1-10, 11-14 and 12-18)
- and some Not connected (NC 13,15,16,17 and 19).
- ******* Only for reference
- To ease the use of flat-cable connectors, here are the notes of wich wires to cross and cut with pin 1 being cable 1:
- Cross:
- 1 19
- 2 21
- 10 23
- Cut:
- 4
- 6
- 8
- 12
- 25
