Keyboard

Version 1.5

5.6 CONNECTION OF SEVERAL KEYBOARDS

If several keyboards (max. 8) are used in a system, the RS-485 bus has to be looped through from

keyboard to keyboard.

Using both RS-485 interfaces (port 1 and 2), the 2nd bus connection must be effected separately as

illustrated above by means of EDA-998 connection kits.

Power supply can be installed either directly at the keyboard or with the included connection box.

5.7 START-UP

After having finished the installation work, switch on the power.

During initialisation (approx. 3 sec.), the firmware version is displayed.

After initialisation, the following message is displayed:

CAM:0001 MON:0001 > DVR

____ [ CAM / MON ] > PTZ

1 2 ... 10 11 12 13 14 15 16 17 18 19 20 ... 39 40
