Multilink

The MultiLink is an intelligent, versatile, programmable, multi-channel data transceiver for building simple or complex networks transferring digital, audio and communications traffic over fibre-optic media. Fibre optics have the valuable advantages of performance over long distance, security from tamper and eavesdropping, and use in high noise environments. Each node has 40 digital inputs with tamper detection support, 32 digital outputs, 4 SPCO relays, 3 RS-232 serial channels, one audio channel and an expansion port for custom features. There is an optional LCD touch panel display for creating programmable user interfaces. Networks of two to sixty-four nodes may be built using point-to-point, single ring or dual-redundant ring architectures. The nodes are intelligent and programmable, with any-to-any logical connectivity for all channels in a system. Simple networks through to complex arrangements such as intercoms and security systems may be quickly built using these versatile building blocks. The MultiLink is available in 2U 19” rackmount version with integral power supply and a stylish wall-mount version requiring only 12V DC. Electrical connection is by two-part screw-terminal connectors enabling rapid and reliable module installation. The fibre connection uses industry-standard ST bayonet couplings and supports the most common fibre media. SMA couplings are available as a factory option. Status LEDs provide an immediate indication of channel activity for rapid diagnosis of network problems. The DF831 is designed and manufactured in the United Kingdom.
