Re: difference between rs232 and null cable

Pin 1 is Data Carrier Detect.
If connected at all, it should be connected to pins 6 an 7 (Request to Send and Clear to Send) on the other end.
In general, however, pin 1 is left open.

For full harware handshaking use:
2 <-> 3
3 <-> 2
4 <-> 6
5 <-> 5
6 <-> 4
7 <-> 8
8 <-> 7

Pins 1 and 9 are not connected

It won't matter if is connected or not because as far as i know in establishment of handshaking dreambox won't use DTR

I think for update pin 2,3,5 is important

Re: difference between rs232 and null cable

pin 2.3.5 must be connected the question is about other pins

RS-232 (Recommended Standard 232) is the traditional name for a series of standards for serial binary single-ended data not work in with my box.?

RS232 is generic, function of software and hardware you will need diffrent types of connections, handshackings and so on, that's why you must have the right rs232 cable

As i say its important just pin 2,3,5

RS232 is generic & just pin 2,3,5 OR important "hardware" What about the software what-to-use?

Re: difference between rs232 and null cable

I just cut a standard cable in two and rewired it. Been using it now for years on my Dreamboxes.
