Overview:
The STest-890 is developed for the installation and maintenance of video monitoring system. It can be used for displaying video,controlling PTZ, DC12V1A power output for camera, Audio input test, generating images, capturing data of RS485 and testing
LAN cable etc. Its functions, easy operation, and convenient portability enable it simple for the contractor to install and maintain
the video camera, promote working efficiency and cost-down the expenditure of the project.

Highlights:
2.8"TFT-LCD , 960(H)X240(V)resolution.
PTZ control. Pan/tilts the P/T unit, zooms in/out the lens, adjusts the focus, aperture and sets and calls the preset position
PTZ continuing rotate test
Video displaying. Automatically adapts and displays the video format of NTSC/PAL.LCD Brightness/Contrast/Color Saturation are adjustable.
Video Level testing, video signals measured in IRE or mV.
Video Generating, The PAL/NTSC multi-system colorbar video generator (seven-system switchable, transmit/receive seven-system colorful imagines)
Data analyst. Captures and analyzes RS485 controlling data to help the technician to find out the problem.
Cable testing. It is powerful in testing LAN cable, measuring the connecting status,displaying the sequence of connection and the NO. of the LAN cable.
Multi-interface and Multi-baudrate. Support RS232 ,RS485 and RS422 interface; baud rate ranging from 150, 600 to 19200bps.
Multi-protocol. Supports more than twenty PTZ protocols. For example, PELCO-P, PELCO-D, SAMSUNG etc.
Lithium Ion Polymer Battery (3.7V DC2000mAh). The device employs advanced power control and protection circuit.
The device is high power-efficient, energy saving and environmental protection. It can last 11 hours for normal use after charging for 4 hours.
