Making a Serial Cable

Last update: 14 January 2004

Making your own Serial Cable
for Adapt11 and MicroCore-11 family products

For most applications you just need RX, TX and Ground. So make a cable with a 9-pin female D-sub connector on one end and a 4-pin Molex on the other end. The connections are as follows:

-J2 pin 1 (RX) to D-sub pin 3 (TX)
-J2 pin 2 (GND) to D-sub pin 5 (GND)
-J2 pin 3 (TX) to D-sub pin 2 (RX)
-J2 pin 4 not connected

To use the DOS batchfiles supplied with Adapt11 and MicroCore-11, you also need to jumper handshaking lines on the 9-pin connector:

- Connect pins 1, 4, & 6 together
- Connect pins 7 & 8 together
- Pin 9 is not used (leave unconnected)
