The F-1MSDI-2ET  – 1 HD-SDI + 2 10/100  Ethernet  + RS 485 + ( Analog Audio optional)  over single fiber Extender

1 Unidirectional HD-SDI
2 Shared Bi-directional 10/100 Ethernet (2 RJ45 Ports)
1 Uni-Directional RS485 (Tx to Rx)
2 Analog Audios (optional)

The Thor Fiber F-M1SDI-2ET is a compact power house that will allow any user to transport one single channel of 1.485Gbps HD-SDI Serial Data Interface uni-directionally while simultaneously transmitting two fast Ethernet 10/100Mb/s data. Furthermore this Thor Fiber Kit of Transmitter and Receiver will send RS485 in reverse for easy control over the kit. This sturdy unit creates an easy drop environment for users that require HD-SDI and Dual Fast Ethernet across any application and even allows additional AUX Cards which can allow a plethora of other options such as RS232 and RS422, and even capable of carrying external analog audio instead of the SDI embedded audio. Thor Fiber has an excellent reputation for high quality and low cost products to help complete your project on time, in a loss free high quality kit that will ensure you stay under budget. Commonly used in security applications, live performance environments, video surveillance, SDI distribution and control in any environment.
