[ddn2us]

hi friends.i want to upgrade my receiver .the RS2322 port of the receiver is female .what type of cable can i use.or how is the pin number connection ???which pin number with which pin number thanks

Hi, It is usual to use a DB9 to DB9 null-modem cable, but it depends on your receiver. Does it not say in the manual?

ya the is like that but some ppl told me the cable should be crossed but that cable is not???...something like that .can i buy that any DB9 cable and use it no oter specification of the cable

 

[Robbo]

Yes, the null-modem is crossed. The wiring of a 9-pin null modem cable is as follows

Connections:
pin 2 ...to... pin 3
pin 3 ...to... pin 2
pin 4 ...to... pin 6
pin 5 ...to... pin 5
pin 6 ...to... pin 4
pin 7 ...to... pin 8
pin 8 ...to... pin 7

pin 3 ...to... pin 2
pin 4 ...to... pin 6
pin 5 ...to... pin 5
pin 6 ...to... pin 4
pin 7 ...to... pin 8
pin 8 ...to... pin 7

I thought the connections were just 2-3, 3-2, 5-5 and screen to screen, works for me.

Robbo is describing the full spec RS232 connections. Almost all PC to STBs just need the data flow, no handshake required.

what does screen to screen mean and also can i copy the stb software to a computer?

 

[Robbo]

The screen is the normally unsleeved stranded wires that are found in screened multicore cable. It is wrapped around all the other cables to provide rf screening or shielding. It is beneath the outer cover of a screened multicore cable.

Whether you can copy from box to PC depends if you have the correct softwares to do so.


and yes, that was the full wiring, as OP didn't say what box he had.

 

[Llew]

The screen connection is the chassis earthing of your equipment (prevents any electrical interference) Pin 5 is the signal ground, that and 2 -3 & 3 -2 are all that's needed for your data exchange to work.

Don't know what your STB is, but that cable is the usual one to use.
