Also used to enter Signal Strength Test Mode to display Received RF Signal strength. Changeover Relay output Normal Operation: Relay is Active Alarm Condition : Relay drops out Signify Learn procedure System Overview The 325 is a transceiver based module on which all channels are auto-acknowledged. Each 325 Module also runs a “watchdog” transmission which periodically sends out a signal to all other 325 Modules to check that all are synchronised. In the event of a signal failure the 325 module has an inbuilt alarm relay, this relay will drop out if any signal is lost or a channel is not acknowledged. Each 325 Module has 8 input and 8 output channels. These are ‘enabled’ on each module by connecting a link on the circuit board. (If the link is not set then the input/output is disabled) When two or more 325 Modules are paired together the 8 i/p channels on each module are automatically mapped to the 8 o/p channels on the other 325 module(s). However the user must ensure that only one of each of the inputs is enabled on one of the 325 Modules. I.e. if i/p1 is enabled on the first 325 Module then it cannot be enabled on any of the other 325 modules within a network;the same applies to the outputs as well This creates an 8 channel telemetry network where any input on any 325 Module can trigger any output on another 325 Module with a maximum of 8 channels. 3.0 System Configuration Input enable jumper links Output enable jumper links There are 3 steps to setting up a system: 1. Pair together all the 325 modules within the network, (max=8) this is known as the ‘Learn Process’. 2. Enable Specific Inputs at the transmitting 325 module 3. Enable Matching Outputs for at the receiving 325 Module Step 1: Learning 325 Modules: 1. Connect power to each 325 Module to be learnt. 2. Enter ‘Learn Mode’ on each 325 Module by pressing the learn switch for 2 seconds. Learn Mode is indicated by the Learn LED being illuminated DS325-2 August ’08 ©2007 RF Solutions Ltd, www.rfsolutions.co.uk Tel 01273 898000 Fax 01273 480661 Page 3 325 Bidirectional Radio Telemetry System 3. When all modules are in learn mode, press the learn switch on the first one for a second time; This 325 Module will then ‘learn’ all the other 325 Modules in learn mode. This is shown by the learn LED Flashing. For each module that is learnt into this 325 module it will turn on an output status lamp, up to a maximum of 8. Each of the remote modules that have been learnt will flash their input status lamps on and off green. 4. Wait for the learn LED to stop flashing on this 325 module, when it has, this 325 will have completed learning – check the to see that all the remote modules have been learnt by confirming that they are all flashing their green input status lamps. The number of learnt modules will be indicated on this 325’s output status lamps. 1 learn = 1 output status lamp on and one remote module which should be flashing its green input status lamps on and off. 5. Learn is complete for this 325 module (this module will now need to be reset by removing and reapplying the power) 6. Press the learn button on each 325 module that is flashing it’s green input status lamps on and off 7. Repeat steps 3 - 5 for each 325 module in the system, 8. To exit learn mode on each module remove power. Note: If two 325Modules are already learnt the learn process will simply relearn again overwriting the old learns.

LED Indication The corresponding Input LED Status will indicate; Red = Input enabled, transmission unconfirmed Green = Input enabled and previous transmission confirmed Off = input not enabled Step 3: Enable an Output: To Enable a matching output on the ‘receiving’ 325 Module insert the ‘O/P Enable’ jumper link against the chosen Output number LED Indication The corresponding Input LED Status will indicate; Red = Output enabled and active i.e. associated connected relay channel is energised. Off = Output not enabled or associated connected relay channel is not energised Note: When the 325 module is powered up it briefly displays which output channels are enabled on the output status lamps Ready to Operate! The 325 Telemetry system is now ready for use. Outputs that have been enabled will follow their matching enabled input status! Output Relay modules can be connected to the required output connectors (please see below). Notes: When setting up a 325 system it is important to remember the following rules: 1. If you enable a channel as an input on a module, you cannot enable that channel as an output on the same module. 2. If you enable a channel as an input on a module, you cannot enable that channel as an input on any other module. 3. If you enable a channel as an output on a module it cannot be enabled as an output on any other module. 4. Inputs and outputs are enabled by connecting the relevant Enable Jumper Links Tip: for complex systems sketch the system out showing which inputs and outputs are valid on each 325Module DS325-2 August ’08 ©2007 RF Solutions Ltd, www.rfsolutions.co.uk Tel 01273 898000 Fax 01273 480661 Page 5 325 Bidirectional Radio Telemetry System Return 325 Module to Factory Default state (Erase): This process erases all pairing information from a given module 1. Connect Power to the 325 Module to be return to Factory Default. 2. Press and hold the Learn Switch for >6 seconds. 3. The module will return to factory learn state; all input LEDs will flash Red/Green, output channel LEDs and connected relay channels will toggle on/off. 4. Repeat for all modules in a system Checking Signal Strength in your chosen installation location (RSSI Mode): Each 325 Module can display the Received Signal Strength (RSSI) to indicate how reliable the Radio signal is. The eight input status LEDs will light according to the signal level. An acceptable signal could be considered as at least 4 Green LED’s illuminated. To enter RSSI Mode: Note: No more than two modules can be in this mode at one time. 1. Remove power from ALL 325 Modules 2. Choose two 325 modules 3. Hold down the learn button on the first 325 module and apply power 4. All input and output status lamps will turn on red, the 325 module is now in RSSI mode 5. Release the learn button, the 325 module will turn off its output status lamps and indicate the received signal strength on its input status lamps (table below shows strengths) 6. Repeat steps 3, 4 and 5 for the second 325 module. 7. Signal strength mode can be toggled between receive test mode and transmit test mode pressing the learn button. 8. Set one 325 modules in each mode (transmit/receive) and use the table below to check the strength. 9. To resume normal operation, on a specific 325 module, remove and re-apply power. Received Signal Strength Indication RF measurement levels are refreshed each second with 4-levels indicated on the Input Channel Status Lamps as follows: Input Channel Status Lamps Received Signal Strength All red < -87dBm 4 green and 4 red Between -87 and -82dBm 6 green and 2 red Between -82 and -77dBm All lamps green > -77dBm Alarm output The alarm output relay is ACTIVE (short circuit) in normal operation. In alarm condition or on power loss the Relay will drop out (open circuit). Alarm condition will be if any of the following situations occur: 1. Acknowledgement of an enabled input channel state change is not received within 30 seconds of the transmission. 2. An Auto Watchdog signal is not received by a unit in a 1 and a half minute time period. 3. An enabled output channel state is not refreshed within 1 and a half minutes DS325-2 August ’08 ©2007 RF Solutions Ltd, www.rfsolutions.co.uk Tel 01273 898000 Fax 01273 480661 Page 6 325 Bidirectional Radio Telemetry System Connecting output Modules to the 325 A range of Relay output modules are available which can be plugged into the 325 via the 2 IDC header connectors. Relay output module options are shown in section 4. Connecting an Antenna The 325 has a board mounted SMA socket; an SMA antenna is provided. Range Note :Range stated is optimum, direct line of sight. In worst conditions this can be reduced by upto 50% The antenna position directly controls the system range. Keep it clear of metal in the area. The best position by far, is protruding from the top of the product. This is often not desirable for practical or ergonomic reasons and thus a compromise may be needed. If an external antenna is used then try to keep it away from other metal items, and in particular large items like transformers, batteries, PCB tracks and earth planes. Note that the space around the antenna is as important as the antenna itself. All radio systems are dependant on a radio signal being received through airspace. The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric conditions. Range is affected by many things, for example local environmental conditions, atmospheric conditions, interference from other radio transmitters. In very worse case applications the range quoted may be dramatically reduced.
