8x8 FIBER-OPTIC TRANSPORT – HEAD END Architect’s Specifications The VIM-1808 is normally used in connection with the VIM-0808 to achieve an 8x8 fiber-optic transport system. The VIM-1808 / VIM-0808 system is normally used as a “drive snake” for sending audio to amplifiers or powered speakers, or for distributed systems utilizing the fiber “pass thru” found on the VIM-0808. This device contains 8 analog line level AND 8 AES digital outputs, and 8 analog line level OR 8 AES digital inputs. The VIM-1808 is supplied with a pair of transmit/receive LC fiber connectors (other connector types possible). It also contains a single LC fiber “thru” connector (transmit only) allowing all data coming into the device to be output on fiber and transported to another location. The VIM-1808 contains the system clock. This clock can be switched to operate at 48k or 96k. The VIM-1808 has an external word clock input on a BNC connector, a word clock output on a BNC connector, and super clock output on a BNC connector. The VIM-1808 can “slave” to an external word clock. There are “sync” status LED’s on the front and rear of the unit. These LED’s will be solid green when in sync, flashing red and green while looking for sync, and solid red when no sync is present. The “control” connection is a TTL data port which appears on an EtherCon® connector. It allows LightViper accessory devices such as the DMX4i (DMX lighting control) or MD3 (RS422/232/MIDI) to be connected to the unit. The EtherCon® output of the DMX4i or RJ45 on the MD-3 is input to the VIM-1808 via the “control” EtherCon® connector, combined with the audio input data, and transported via fiber to the VIM-0808. This data is then output from the “control” EtherCon® connector on the VIM-0808 and input into a DMXo or MD-3 where the TTL data is translated back into the original format. AC power is via a standard IEC connector. The unit can operate at any voltage 50-60Hz, 90-250v AC. The device shall be a 1U rack mount unit with venting on the front panel and on the reversible rack ears. It shall be fan cooled. The device shall provide 8 analog line level outputs on 1 DB25 connector AND 8 AES digital outputs on 1 DB25 connector, 8 analog line level inputs on 1 DB 25 connector OR 8 AES digital inputs on 1 DB25 connector. The device shall contain multi mode optics utilizing an SFP transceiver, with single mode SFP optics available as an option. There shall be a transmit/receive fiber optic pair presented on LC connectors (other connector types possible). There shall be a single LC fiber optic “thru” connector (transmit only) allowing all data coming into the device to be output on fiber and transported to another location. There shall be no limit to the number of units which can be connected via the fiber “thru” to achieve a distributed system. The device shall contain the system clock which can be set via a manual toggle switch which selects whether the device operates at 48k or 96k. The device shall be capable of slaving to an external clock. The device shall have an external word clock input on a single BNC connector, a word clock output on a single BNC connector, and super clock output on a single BNC connector. The device shall contain LED sync indicators on the front and rear of the unit. These LED’s will be solid green when in sync, flashing red and green while looking for sync, and solid red when no sync is present. There shall be a TTL data port labeled “control” presented on an EtherCon® connector. The device shall operate at any voltage 50-60Hz, 90-250v AC utilizing a standard IEC connector. The device shall contain a 5x20 mm, 1A Slo-Blo power fuse. The device shall be the LightViper VIM-1808.
