1E
DESCRIPTION The
921D-XXX
VT/VR(S)
Series
multiplexer
simultaneously transmits one channel of real-time 10-bit digital video and one or two channels of bi-directional data, contact closure or audio and one channel of 100M Ethernet both directions over one multimode or single-mode fiber optic cable. The module is universally compatible with major CCTV and Access Control Manufactures and supports bi-directional transmission of RS-232, RS-422, or RS-485 data interfaces and all major data protocols. The modules incorporate Power, Carrier Detect, Data Transmit and Data Receive status indicating LED’s for each individual channel for monitoring proper system operation. The modules are available in either stand-alone or rack mount version.
FEATURES z Optical automatic (OAGC).
z A 921D-XXX VT/VR(S) pair transports one
channel of high quality composite video in one direction and one or two channels of data, contact closure or audio and one channel of Ethernet in both directions over one optical fiber.
z Circuit protector. z Hot-Swappable Rack Modules. z P/T/Z Control Formats (Data Interface): Duplex
switch-selectable RS232, RS422, RS485 or Manchester PTZ.
z Exceeds RS250C Short Haul Specifications
for SNR, Differential Phase, and Differential Gain. z Video channel: 8 MHz bandwidth;
z Fully compatible with IEEE 802.3,100Base-T,
100BaseFX and Ethernet Standards.
z Eliminate EMI, RFI and ground loop.
compatible with NTSC, PAL, SECAM.
z Surge Protection for video, data and power supply.
z SNR≧70 dB at max optical input power.
z Up to 80 Km range depending on model.
z 10 bit linear PCM video encoding.
z Standalone
method: 19-inch wall-mount, or desktop mount.
z Video Resolution: > 680 TV lines.
