3. 5 rated enclosure the Emlink1 is designed for indoor and outdoor use Each Emlink1 has 2 input channels which can accept either an analogue input signal from 0 to 24V DC for remote monitoring or a digital signal set by 4 thresh olds Outputs 1 amp 2 are volt free relay contacts and can be configured to work in 3 modes momentary toggle and timed outputs with intervals from 1 second to 30 minutes An option to pair its own input to output allows the Emlink1 to work as a timer as well as transmitting its status to other paired devices The third output can be switched between a tamper relay and a 3rd channel In tamper mode the Emlink1 can monitor local and remote tamper switches lost status update signal from remote units or report a paired input from a remote unit When not used as a tamper circuit the third channel can function as a momentary volt free output Other features include a built in signal strength meter site survey mode for the engineer to check signal strengths when installing units and a RS232 RS485 serial interface for transmission of protocols Pelco P amp D Emlink and an open channel protcol Page 3 Status Signal LED s Each input output on the Emlink1 has a closely mounted status LED to indicate the channel is active For the signal strength a strip of 6 LED s is mounted in the centre at the top of the Emlink1 A brief description of the status signal LED s is listed below Signal LED s
4. The signal LED s have 2 meanings when the display raises from the bottom upwards this indicates a received signal strength depending on the receive level will depend on how many LED s will light For a transmission the LED s will pulse from the centre outwards Inputs Outputs 1 amp 2 The input output LED s for channels 1 amp 2 flash at half second intervals when a channel is active Channel 3 Tamper The status LED flashes at half second intervals providing the tamper fault is local if a remote tamper fault has been detected the status LED will pulse twice When using this output as a third channel the status LED will only flash at half second intervals when active Data Channel Data Models Only The status LED on the data channel emits a short pulse when sending or receiving data over the RS232 or RS485 port If the status LED stays on continuously for half a second or more there is a problem with either the serial port settings or the protocol used Power Saving During continuous data transmission it will be noticed that the status signal LED s will dim this is a normal behaviour to save power The status LED s will also extinguish when the tamper switch is held down for more than 5 seconds Page 9 Emlink Programming Repeat Mode Pairing In this mode briefly pressing the right switch of the Emlink1 transmits a pairing signal to another device If the Emlink1 receives a pairing signal from an

7. come this the Emlink1 can be programmed to transmit a status update at a given period Status updates have 2 main functions 1 If a receiver becomes out of sync with the transmitter i e a power cut receiving automatic status updates will re sync the receiver 2 The receiver can also be programmed to detect missing status updates if 2 or more status updates are missing the receiver generates a tamper fault and the tamper LED will flash twice to indicate a remote tamper fault To enable status updates please refer to the programming section Input channels analogue updates When an Emlink1 transmits a status update it measures the input voltages and transmits this level as a digital value in 0 1V steps The purpose of this feature is for remote data logging etc and has no affect on the inputs previously described Repeat Function An Emlink1 can repeat other Emlink1 s signals The repeating Emlink1 still can use its own inputs and outputs while repeating other units For an Emlink1 to repeat another units data it physically has to receive the first transmission and then re transmit this on the same frequency This is perfectly ok for status updates but for the data channel if a high data through put is required we cannot guarantee its operation RF Channel Selection 7 RF channel channels are available in the 433 434MHz band All Emlink1 units must be on the same channel for them to communicate If a particular channel is found to
