Audio & Video Consoles/Extenders

The ComNet FDC8 Series contact closure transmitter and receiver provides transmission of up to eight independent contact closures over one RS232 link or optical fiber. Microprocessor-based logic sends the contact information in packets that are ordered and encoded, ensuring extremely robust transmission. Packets that are garbled, packets out of sequence, and transmission bit errors will not cause random changes of state on the contact relays. Also, the mechanical latching relays maintain their state even when the unit loses power. Each module incorporates power and individual status indicating LEDs for monitoring confirmation of contact closure of each of the eight channels. These units are interchangeable between stand-alone or card mount configurations.

Features for FDC8 Series

• Point-to-Point architecture
• Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
• SPST latching relays
• Microprocessor-based logic and latching relays in receiver unit eliminate random contact closure status in the event of loss of link or loss of prime operating power.

Applications

• Alarm Event Triggering
• Building Automation and Environmental Control Systems
• Fire and Alarm Systems
• Gate Control
• PIR Signal Transmission

The ComNet FDC24NL Series contact closure transceiver units provide transmission of up to twenty four independent duplex dry switch or relay contact closures using a single SFP optical port or any four-wire RS-422 copper circuit. The FDC24NL Series supports an integrated field expandable RS-422 data bus allowing up to 12 uniquely addressed units to be connected to the bus providing up to 288 unique duplex contact closures over a single SFP optical port or RS-422 copper circuit.

The contact closure information is sent in packets that are ordered and encoded, ensuring extremely robust transmission. Packets that are garbled, packets out of sequence, and transmission bit errors will not cause random changes of state on the contact relays. One relay can be optionally re-purposed as a summary fault alarm contact and is triggered in the event that the unit loses fiber or RS-422 bus communications. The FDC24NL series is offered with non-latching solid state relays. Each module incorporates link and individual status indicating LEDs for monitoring confirmation of contact closure input and output of each of the twenty four channels. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 or DINBKT4 adaptor plate.

The ComNet™ FVT81M1 and FVR81M1 multiplexers simultaneously transmit eight channels of video over one optical fiber utilizing state-of-the-art digital encoding and decoding for high-quality video transmission. These environmentally hardened units are ideal for use in unconditioned roadside or out-of-plant installations. These units are completely transparent to and universally compatible with any NTSC, PAL, or SECAM CCTV camera systems. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.

The ComNet™ FVR4C4B Video and Contact Closure Receiver unit supports four independent channels of video and four independent dry contact closures over four separate optical fibers. The FVT1C1B-M video mini-transmitter supports transmission of a fixed video and a contact closure signal using an 8-bit digitally encoded signal on one multimode or single mode fiber optic cable. State-of-the-art 8-bit digital decoding is utilized for the four video channels. The contact closure channels may be used with triggered-event CCTV camera systems, or other applications such as access controlled gates, doors, or other equipment requiring remote actuation and control. Plug-andplay design ensures ease of installation, and no electrical or optical adjustments are ever required.

The KanexPro EXT-HDBT70M is an UltraSlim, HDCP 2.2 compliant extender set consisting of a transmitter and receiver. It uses HDBaseT technology to transmit uncompressed, high-resolution 1080p/ 4K signals from transmitter to the receiver via a CAT5e/CAT6a cable at a distance of up to 70/40m. Moreover, the extender set supports CEC, bi- directional RS232 & IR control, and bi-directional PoH (power over HDBaseT) function.

Applications

Ideal for use in digital signage applications, healthcare AV, control rooms, educational facilities, airports, commanding centers and home theater.
