KRAMER ELECTRONICS C-GM-XX FAMILY OF NON-
PLENUM “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, or 5 BNC connectors for
RGBHV. Please note that the C-GM-XX family is not plenum rated. If local codes
require plenum rated cables, see Kramer’s CP-GM-XX family.
DESCRIPTION
Kramer’s C-GM-XX cables are built with a high quality molded 15 pin high density VGA
type connector permanently installed on one end, and only the exposed 5 coaxes 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
