TeleFlash to PC Serial Interface Cable Pinouts

The TeleFlash instruments are interfaced via RS232 cabling. Below is a pin to pin diagram of the standard cable which is supplied with the instrument.

 

DB9s (female) DB25p (male)
2 2
3 3
5 7
6 & 8 6 & 8 & 20
  4 & 5

Note that there are four jumpers; one inside the DB9s and three within the DB25p. It appears that the jumpers serve to completly disable hardware handshake.
