Connection
The keyboard can control the PELCO protocols
CM6700 & CM6800. For example the keyboard
connects with the PELCO CM6700 matrix in order to
introduce the connection between the keyboard and
the matrix.
There are two kinds of keyboard connection
interface on the CM6700 matrix back plate. One is
the local keyboard connection interface RJ45
("LOCAL KEYBOARD"), which can control the single
keyboard within the distance of 7.6m. The other is
the remote interface RS422 ("REMOTE
KEYBOARD(s)"), which can connect with the
keyboard's RS422 Iinterface. The maximum distance
is 1200m.
