I have done some looking for cables for my ATEN KVM. I think I will
need:
1) to connect inputs to KVM:
monitor - VGA cable, KVM monitor end male to KVM end male
mouse - PS/2 mouse to KVM end male PS/2
keyboard - PS/2 keyboard to KVM male PS/2
2) to connect KVM to each CPU:
monitor - CPU end, VGA male to KVM end female VGA
mouse - KVM CPU PS/2 male to PS2 mouse
keyboard - KVM CPU PS/2 male to PS2 keyboard

agree???

Thanks
Al


You have me at a disadvantage here, as you can
see the items in question.

I'm surprised the VGA cable to each CPU isn't male
on both ends. They should really use cable choices
the user is likely to already have.

Yeh me 2. I chcked the KVM, and all 4 VGA ports have pins sticking
up, hence requiring a cable female plug. Right?
Thanks

See Johns answer.

Are you sure it's a VGA ? It has 15 pins, with a
keying pin missing ? I had a VGA cable once, that
still had pin 9 on both ends. And other cables
have pin 9 missing so +5V cannot power EDID inside
the monitor.

http://pinouts.ru/Video/VGA15_pinout.shtml

Pin 9 (formerly +5V for EDID, removed)

5 4 3 2 1
GND RES BLUE GREEN RED
Video
10 9 8 7 6 Card
SGND --- BGND GGND RGND Female

15 14 13 12 11
SCL VSYNC HSYNC SDA ID0

The 1-2-3-6-7-8 cluster are intended for
"three minicoax routing" inside the cable. It
makes it easier to affix coax because of those
pin choices. The HSYNC/VSYNC use coax on some
VGA cabling, but on other they're just routed
as if they were low frequency signals (poorer
impedance characteristic allowed). SGND could
be part of the VSYNC/HSYNC/CSYNC cluster. SDA
and SCL allow the video card to read-out the
EDID eeprom in the monitor.

If the connector has more pins than that, then
you need something different.

The VGA-looking KVM port has 15 pins, 3 rows of 5. Looks like VGA to
me.

There is no missing pin 9 as there is not in the pic in above web
page. Otherwise they are the same.
