I can't find an answer to this anywhere so I thought I'd ask around here.

I need a cable with 13 or more wires in it, preferably with a DB-15 or DB-25 connector, but I can't find one anywhere. I grabbed some DB-25 serial cables but they only had 6 wires in them (not all pins are used), and I can't find a reliable way to discover how various cables are wired before I cut them in half and find out myself.

Anyone know a cheap source for 13+ wire cables? Preferably thin and black. I can also just get the cable and wire up D-sub terminals, but I wouldn't know where to start to look for this...

Any help or resources would be much appreciated, thanks.

A DB-25 cable with only 6 wires is probably configured as a nullmodem. Try to find a straight EIA-232 cable for connection between DCE (Data Communication Equipment, i.e. modem) and DTE (Data Terminal Equipment, aka PC), this should have all 25 pins connected.

A DB-15 VGA cable should also give you 13 wires, but return ground for red, blue and green may share the same wire (they shouldn't).

  • \$\begingroup\$ Thanks, I'll look around. As far as I can tell most VGA cables I find are 12 wires: 8 signal + ground, and 3 RGB. Also, I need 13 wires with small diameter.... \$\endgroup\$ – granto Apr 8 '12 at 16:03
  • \$\begingroup\$ Also if you take a look at the cables I bought here, it seems to be a DCE to DTE, no? There's just something I'm not getting here. techforless.com/cgi-bin/tech4less/… \$\endgroup\$ – granto Apr 8 '12 at 16:13
  • \$\begingroup\$ @granto - not clear from the description on the site. Anyway, a nullmodem cable is for connecting DTE to DTE (PC to PC). \$\endgroup\$ – stevenvh Apr 8 '12 at 16:16

Most legacy parallel printer cables should have 13+ conductors.

The PC type will traditionally have a DB-25 male connector on one end and a Centronics male on the other end.

A DB-15 connector is not what most people will think. Most are thinking of a DA-15 connector.
