Pin Parameter DescriptionPin 9 RS-232 Tx Serial RS-232 connection. This bus must use a ground connection between devices to operatecorrectly.Pin 10 RS-232 RxPin 13 Secondary RS-485 –Not usedPin 14 Secondary RS-485 +Pin 15 CANL –Pin 16 CANH +4.5 Inputs and OutputsThe I/O base board is a Modbus slave device that communicates using Modbus commands. Refer to the Modbus Registerssection for more descriptions of each Modbus register on the DXM100-Sx Modbus Slave.4.5.1 Universal InputsThe universal inputs on the DXM100-Sx Modbus Slave can be programmed to accept several different types of inputs:• Discrete NPN/PNP• 0 to 20 mA analog• 0 to 10 V analog• 10k temperature thermistor• Potentiometer sense• Bridge• NPN raw fastAny input can be used as a synchronous counter by configuring the input as a discrete NPN/PNP input.Use the DXM Configuration Tool tool to write to the appropriate Modbus registers in the I/O board to configure the inputtype. The universal inputs are treated as analog inputs. When the universal inputs are defined as mA, V, or temperature, useModbus registers to configure the operational characteristics of the inputs. These parameters are temperature conversiontype, enable full scale, threshold and hysteresis. Refer to the DXM100 Controller Instruction Manual (p/n190037) for theparameter definitions.When a universal input is configured as an NPN or PNP input type, it can be enabled to be a synchronous counter. Enablethe counter function by setting Modbus register 'Enable Rising' or 'Enable Falling' to 1. SeeModbus I/O Registers for theDXM100-S1x I/O Base Board on page 21 for universal input register definitions.Pin Universal Input Modbus Register Description27 4 4 Program the universal inputs to accept input types NPN, PNP, 10k thermistor, 0 to 10 V, 0 to 20mA, or potentiometer. The default setting is 8: NPN raw fast. To set the input type, write thefollowing values to the Input Type Modbus registers defined inModbus I/O Registers for theDXM100-S1x I/O Base Board on page 21.0 = NPN1 = PNP2 = 0 to 20 mA3 = 0 to 10 V dc4 = 10k Thermistor5 = Not used6 = Not used7 = Bridge8 = NPN Raw Fast (default)28 3 331 2 232 1 1Thermistor InputA thermistor input must use a 10k temperature thermistor between ground and the universal input. The thermistormust be a 10k NTC (Banner model number BWA-THERMISTOR-002) or equivalent. Select the temperatureconversion of degrees C (default) or degrees F by writing Modbus registers defined inModbus I/O Registers for theDXM100-S1x I/O Base Board on page 21.DXM100-Sx Wireless Modbus Slave18 www.bannerengineering.com - Tel: +1.763.544.3164
