Need cables for ATEN CS104 4-port 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. Paul Yeh me 2. I chcked the KVM, and all 4 VGA ports have pins sticking up, hence requiring a cable female plug. Right? Thanks Al |

Thanks Al 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. Paul |

And other cables have pin 9 missing so +5V cannot power EDID inside the monitor. The VGA-looking KVM port has 15 pins, 3 rows of 5. Looks like VGA to me. http://pinouts.ru/Video/VGA15_pinout.shtml There is no missing pin 9 as there is not in the pic in above web page. Otherwise they are the same.
