Sonifex Show Redbox RB-IPE IP Extender At IBC 2012

Sonifex are showing on stand 8.E61 at this year’s IBC, the new Redbox RB-IPE IP Extender for GPIO & Analogue Control Signals.
Eamonn Heffernan, Sales Manager, commented: "The RB-IPE is a 1U rackmount unit designed to provide remote control of GPIO and analogue control voltages over an Ethernet network. It is configured using a built-in web server and two units can control each other across an Ethernet network, or a single unit can be controlled via Ethernet commands and the web server interface. It is ideal for the remote control of equipment at unmanned posts, outstations or transmitter sites."
The RB-IPE has 16 x general purpose inputs on 8 x RJ45 connectors, consisting of 8 x isolated current sink inputs and 8 x pull to ground protected inputs; and 16 x general purpose outputs on 8 x RJ45 connectors using 8 x isolated relay change-over contacts and 8 x opto-isolated contacts. These rear panel RJ45 connectors have an LED for each GPIO which shows its state.
On another 8 x RJ45 connectors there are also 8 x 0 to 3.3V/5V/12V input signals and 8 output signals nominally at 0 to 3.3V output, with other output voltage configurations possible. The outputs can all be controlled from the inputs of another RB-IPE, or from Ethernet commands, allowing any tallies and control signals, together with analogue potentiometer movements, to be sent across a network, e.g. for remote alarm points, to trigger failure alarms at a transmitter site and to control remote equipment.
When two units are connected together at different sites, if a general purpose input state changes at one site the unit sends the new state to the other site and the appropriate opto-isolator output changes on that unit. Similarly input voltage controls are monitored and the changing voltage is sent to the remote unit where an output voltage changes accordingly.
