Pin DescriptionPin 4 Solar or backup battery positive input. Battery voltage must be less than 15 V dc. Use only a sealed leadacid (SLA) battery.5.2.1 Using Courtesy Power or Switch PowerPin 18 of the DXM100-Sx Modbus Slave is a constant power source that supplies 5 volts up to 500 mA.Pins 21 (switch power 2) and 30 (switch power 1) are switched power outputs. Configure the switched power outputs usingModbus registers or by using the DXM Configuration Tool's Settings > I/O Board screen. The output voltage can beselected and is controlled using a Modbus register on the I/O board (Modbus slave ID 200). The voltage options are:• 5 volts or 16 volts for DXM100-B1 models; or• 5 to 24 V dc for DXM100-B2 models.Turn the switched power on or off using the output register 505 for switch power 1 or 506 for switch power 2. Forcontinuous power, set the Default Output register to 1, then cycle the power.Switch Power Enable Register Voltage Register Default Output Register Output Register1 (pin 30) 2201Write a 0 to turn OFFWrite a 1 to turn ON (default)3601Write a 0 to select 5 V (default)Write a 1 to select 16 V3602 5052 (pin 21) 2251Write a 0 to turn OFFWrite a 1 to turn ON (default)3621Write a 0 to select 5 V (default)Write a 1 to select 16 V3622 506Enable RegisterConfiguration registers that turn on the ability to use the switched power output.Default setting = ONVoltage RegisterConfiguration registers that define the output voltage to the switched power output.Default setting = 5 VDefault Output RegisterConfiguration registers that turn on the switched power outputs for continuous power out.Set register to 1 for continuous power. Cycle power if this register is changed.Default setting = 0Modbus Output RegisterTurn on or turn off the voltage output. If both outputs 505 and 506 are turned on at the same time but are set todifferent voltages, the output voltage is 5 V for DXM100-B1 models and set to the lower voltage setting forDXM100-B2 models.5.2.2 Associating a Switched Power Output to an InputUse the DXM Configuration Tool to associate a switched power output to a universal input in most situations.Switched power 1 and 2 (pins 30 and 21) can be associated to any Universal input to apply power a sensor, take a reading,and then remove power from the sensor. This conserves power in battery-operated systems. The switched power supplycan be used in one of two different ways: supplying courtesy power to an output pin or associated to an input. (Only onemethod can be active at a time.)To manually configure the switched power output using I/O board Modbus registers, write the specified value to the listedregister.DXM100-Sx Wireless Modbus Slavewww.bannerengineering.com - Tel: +1.763.544.3164 25
