C-GM/XL-XX “INSTALLATION” CABLES
INTRODUCTION
Thank you for your purchase of Kramer’s single-ended installation cables. They are
designed to be pulled through a wall, raised floor, ceiling, table, or other hidden space,
then have the bare end terminated with either another 15 pin and include EDID
capabilities, or 5 BNC connectors for RGBHV.
DESCRIPTION
Kramer’s C-GM/XL-XX cables are built with a high quality molded 15 pin high density
VGA type connector permanently installed on one end, and the exposed 5 coaxes and
two wires on the other. The raw cable used for is Kramer BC-5X28 which contains 5
high resolution mini coaxes color-coded red, green, blue, yellow, and black which will
correspond to red, green, and blue video, plus separate horizontal and vertical sync, in
that order. Since there are only 5 coaxes, it is not possible to pass extra pins for plug &
play or ID bit support.
INSTALLING A VGA CONNECTOR
We recommend using a high quality solder type VGA connector such as Kramer’s model
“2551-815004”. This item can be obtained from the same vendor you purchased the
cable from. Each of the 5 coaxes are already prepped by separating the outer shield
from the center conductor using heat shrink, then each exposed tip has been tinned
making it easier to solder to the pins of a VGA connector. Here is the recommended pin
configuration for typical VGA:
Red center conductor Pin 1
Red shield Pin 6
Green center conductor Pin 2
Green shield Pin 7
Blue center conductor Pin 3
Blue shield Pin 8
H sync (yellow coax) center conductor Pin 13
H sync shield Pin 10 and 11
V sync (black coax) Pin 14
V sync shield Pin 10 and 11
INSTALLING 5 BNC’S
Using Kramer’s high quality radial compression termination system, or other system
compatible with typical 26/28 gauge mini coax, install BNC’s on each of the 5 coaxes,
noting the following color scheme:
Red coax Red video
Green coax Green video
Blue coax Blue video
Yellow coax Horizontal sync
Black coax Vertical sync
