Notes:
1) 10-conductor shielded cable is www.allelectronics.com 10CS22.
2) HD15M (K3-side cable connector) is www.mouser.com 156-1815-E, HD15F (KPA500-side cable
connector) is 156-1915-E, and hoods are 156-2009-EX.
3) Shield of 10-conductor cable soldered to connector shells.
If you wish to purchase, rather than build a cable, visit www.cablewholesale.com and purchase a 6’
SVGA cable, part number 10H1-20206NF. Modify the cable by breaking off the pins shown below.
Grasp the pin right up against the connector body with long-nose pliers, and carefully bend the pin back
and forth until it breaks off.

Rather than break off the cable pins, you can purchase a 31H1-05200 HD15 M/F adapter (also called a
“port saver”) and pull out the pins as shown above. Then plug this in-line with the cable. This preserves
all cable pins for any potential future use.
Some other cable lengths available from Cable Wholesale: 1-ft HD15 M/F 10H1-20201NF, 3-ft 10H120203NF, 10-ft HD15 M/F 10H1-20210.
Another place for purchasing VGA cables with all pins connected strait through is www.l-com.com.
Some of their part numbers: 3ft HD15 M/F CGSVGAMF-3, 5ft HD15 M/F CGSVGAMF-5, and 10ft HD15
M/F CGSVGAMF-10.
NOTE: Not all VGA or SVGA cables have all 15 pins connected straight through.
Additionally, pins in some cables are shorted together and/or shorted to
ground. The Cables from the two sources I reference above DO have all 15 pins
connected through, and none are connected to each other or to ground.
