Quick Start Guide of Digital Video Recorder15To connect PTZ to the DVR:1. Disconnect pluggable block from the RS-485 terminal block.2. Press and hold the orange part of the pluggable block; insert signal cables into slots and release the orangepart. Ensure signal cables are in tight.3. Connect A+ on PTZ to T+ on terminal block and B- on controller to T- on terminal block. Fasten stopscrews.4. Connect pluggable block back into terminal block.To connect a controller to the DVR:1. Disconnect pluggable block from the KB terminal block.2. Press and hold the orange part of the pluggable block; insert signal cables into slots and release the orangepart. Ensure signal cables are in tight.3. Connect Ta on controller to D+ on terminal block and Tb on controller to D- on terminal block. Fasten stopscrews.4. Connect pluggable block back into terminal block.Make sure both the controller and DVR are grounded.Termination Switch Operation This function is applicable to the TVI-D14xx and TVI-D24xx series DVR. The termination switch is placed on the mainboard instead of the rear panel. Open the upper cover and turnon/off the SW switch if needed.Purpose:To connect the DVR with several speed domes, the bus topology can be adopted, which means the speed domesare connected with each other via the R+ and R- of RS-485 serial interface. But due to the impedance of 485 wire,the longer the wire is, the greater the impedance gets.To avoid the signal reduction caused by the great impedance of long distance transmission, please connect two120Ω resistors in the circuit: one resistor between the DVR and the nearest speed dome, and the other one after thefurthest speed dome. |
