Keyboard Control Simulator
To run the Keyboard Control Simulator under MS-Windows, please select
Start->Programs->Hyper Electronics Mappers->KCtrlSimulator, and the screen will be
shown as below.
Please note that most of the buttons correspond to the keypads on the front panel. If you
connect the PC through RS-232 and use an RS-232/RS-485 converter to connect to
multiple DVRs, you would be able to control multiple DVRs via the simulation software.
Please refer to
Section 3.2 Optional Connections to connect/cascade the DVRs to the PC.
To select the DVR to control, please click on the button as circled in the above diagram to
set the corresponding DVR ID. Please note that the
RS-232/422/485 setup (Section 6.9) ,
including the DVR ID, in the DVRs must be configured correctly (Model must be set as
Control Protocol). Please use the buttons MAIN-AUX ON, MAIN-AUX OFF,
CALL-AUX ON, CALL-AUX OFF to switch on/off the output of the controlled DVR.
Note: UP-LEFT, UP-RIGHT, DOWN-LEFT, and DOWN-RIGHT are newly added to
control the PTZ cameras diagonally.
