7. OPERATING THE DVR VIA SYSTEM KEYBOARDS
Operating the DVR via NV-KBD30 and NV-KBD70 system keyboards.
NDR-EA2104, NDR-EA2208 and NDR-EA2416 may be remotely controlled using NV-KBD70
or NV-KBD30 keyboard. System is controlled either via RS-485 or RS-232 (after using an
appropriate adapter) port connection. Thanks to this, controlling large systems is possible (up to 9
DVRs with NV-KBD30 and up to 32 in case of NV-KBD70). The RS-485 wire length should not
exceed 1200m. In such a system, devices are cascade connected, with taps length not exceeding 1,5m.
Keyboards have their keys associated in accordance with respective buttons in the DVR, serving the
same function. Additional informative feature is the LCD display located in the keyboard, displaying
information about active functions, transmission parameters etc.
