For moreinformation, refer toSetting the Modbus Slave ID on the I/O Base Board.5.1.2 I/O Board JumpersHardware jumpers on the DXM I/O board allow the user to select alternative pin operations. Turn the power off to the devicebefore changing jumper positions.Jumper Function PositionsE Courtesy power output Jumper 2 is the power jumper for pin 45. Jumper 1 is the power jumper for pin 35.• The pin 45 jumper selects 2.7 V when in the "a" position and 12 V battery in the"b" position.• The pin 35 jumper selects 4.2 V when in the "a" position and device power onpin 2 in the "b" position.G1 RS-485 Modbus Slave orRS-232 Flow ControlDefines the operation of pins 11 and 12. Set the jumpers to use pins 11 and 12 as asecondary Modbus RS-485 slave port or flow control pins for the RS-232 port. Bothjumpers must be set to the same operation, RS-485 Modbus Slave or Flow control.The default setting is RS-485.G2 Generic RS-232 Serial Port orCAN Serial PortDefines the operation of pins 9 and 10. Set the jumpers to use pins 9 and 10 as a CANserial port or a generic RS-232 serial port. Both jumpers must be set to the sameoperation, CAN or RS232.The default setting is CAN serial port.G3 Analog output characteristicsfor AO2 (pin 32) and AO1 (pin33)Defines current (0–20 mA) or voltage (0–10 V) for analog output 1 and 2.By default, current (0–20 mA) is selected using jumpers 1 and 2 and registers 4008 and4028 contain a value of 2.To select voltage (0–10 V) for output Aout1, set jumper 1 in the voltage position (V) andset Modbus register 4008 on the I/O board (SID 200) to 3.To select voltage (0–10 V) for output Aout2, set jumper 2 in the voltage position (V) andset Modbus register 4028 on the I/O board (SID 200) to 3.5.2 Applying PowerApply power to the DXM Modbus Slave using either 12 to 30 V dc or a 12 V dc solar panel and 12 V sealed lead acidbattery.If the incoming voltage drops below 11.2 V dc, the cellular modem does not turn on and will not turn on until the voltage isabove 11.8 V dc. A text file (CmVMon.txt) on the internal micro SD card saves the periodic sampling of the incomingvoltage. If cellular operation stops because of voltage, it is logged in this file.Pin DescriptionPin 1 No connectionPin 2 12 to 30 V dc input (+) or solar panel connection (+)Pins 3, 5, 8, 13, 18, 24, 25,31, 34, 36, 41, 44, 48Main logic ground for the DXM Modbus SlavePin 4 Solar or backup battery positive input. Battery voltage must be less than 15 V dc. Use only a sealed lead acid (SLA)battery.DXM150-Sx Wireless Modbus Slave24 www.bannerengineering.com - Tel: +1.763.544.3164
