Overview 
The KTD-405 Series controller keyboards are compatible with 
many GE Security products, including switchers, domes and 
DVRs. This series has been designed to control up to 1,024 
cameras or receivers and 128 switched monitors. The 
keyboards can also control Digiplex® systems, and an RS422/ 
RS485 communication port enables the unit to operate a 
number of components: SymDec™ 16 plus 4; SymSafe™ and 
SymSafe Pro; DVMRe; multiplexers; matrix switchers; alarm 
interfaces; Legend 
units can select and switch video, initiate camera tours and 
select monitors.
The keyboards operate in one of two modes: discrete zone or 
standard Digiplex. In the discrete zone mode, the system can 
be divided into 32 zones with up to 32 cameras in each zone. 
Multiplexers serve as the switching devices in this mode. In 
standard Digiplex mode, a matrix switcher is the system’s 
primary switching device. Other features include a three-axis 
joystick (two-axis joystick in the KTD-405-2D) for exceptional 
pan/tilt maneuverability in PTZ applications and dedicated 
recorder operation keys. When call-ins occur, a built-in 
annunciator alerts the user that attention is needed. These 
keyboards can stack up to 32 call-in requests in the order they 
were received. The first three call-in requests are displayed 
and a reminder tone sounds every 15 seconds until all active 
call-ins have been cleared from its queue. Authorized 
personnel can program the unit and other Digiplex 
components through confidential access codes.
