This state is called the INIT* state.INIT* state defaults:Baud rate: 9600Address: 00hChecksum: disabledForcing the system into the INIT* state does not change any parameters in the system's EEPROM. When the system is in the INIT* statewith its INIT* and GND terminal shorted, all configuration settings canbe changed and the system will respond to all other commandsnormally.Changing Baud Rate and ChecksumBaud rate and checksum setting have several things in common:• They should be the same for all systems and host computer.• Their setting can only be changed by putting a system in the INIT*state.• A changed setting can only take effect after a system is rebooted.To alter baud rate or checksum settings you must perform the following steps:1.
Power on all components except the ADAM-5000 system2. Power the ADAM-5000 system ON while shorting the INIT*and GND terminals as shown in Figure A-3.ADAM-5000A-9Quick Start Example++Vs-GNDINIT*COMDATA+DATA-Figure A-3 Grounding the INIT* terminal3. Wait at least 7 seconds to let self-calibration and ranging takeeffect.4. Configure the baud rate and/or checksum status.5. Switch the power to the ADAM-5000 system OFF.6.
Remove the grounding on the INIT* terminal and power theADAM-5000 system ON.7. Wait at least 7 seconds to let self-calibration and ranging takeeffect.8. Check the settings. (If the baud rate has changed, the settings onthe host computer should be changed accordingly)A-10ADAM-5000Appendix AA.4 A Distributed ADAM-5000 Network SystemHook-upThe figure below gives an example of how multiple ADAM systemsshould be connected:Figure A-4 ADAM-5000 network system hook-upADAM-5000A-11Quick Start ExampleThis page intentionally left blankA-12ADAM-5000BData Formatsand I/O RangesData Formats and I/O RangesB.1Analog Input FormatsThe ADAM analog input modules can be configured to transmit datato the host in Engineering Units.Engineering UnitsData can be represented in Engineering Units by setting bits 0 and 1 ofthe data format/checksum/integration time parameter to 0.This format presents data in natural units, such as degrees, volts,millivolts, and milliamps.
The Engineering Units format is readilyparsed by the majority of computer languages because the total datastring length, including sign, digits and decimal point, does not exceedseven characters.The data format is a plus (+) or minus (-) sign, followed by five decimaldigits and a decimal point. The input range which is employeddetermines the resolution, or the number of decimal places used, asillustrated in the following table:Input Range±15 mV, ±50 mV1 µV (three decimal places)±100 mV, ±150 mV,±500 mV10 µV (two decimal places)±1 V, ±2.5 V, ±5 V100 µV (four decimal places)±10 V1 mV (three decimal places)±20 mA1 µA (three decimal places)Type J and Tthermocouple0.01ºC (two decimal places)Type K, E, R, S, and BthermocoupleB-2Resolution0.1ºC (one decimal place)ADAM-5000Appendix BExample 1The input value is -2.65 and the corresponding analog input module isconfigured for a range of ±5 V.
The response to the Analog Data Incommand is:-2.6500(cr)Example 2The input value is 305.5ºC. The analog input module is configured fora Type J thermocouple whose range is 0ºC to 760ºC. The response tothe Analog Data In command is:+305.50(cr)Example 3The input value is +5.653 V. The analog input module is configured fora range of ±5 V range. When the engineering units format is used, theADAM Series analog input modules are configured so that theyautomatically provide an over range capability.

It is specifically developed for industrialmulti-drop systems that should be able to transmit and receive data athigh rates or over long distances.The specifications of the EIA RS-485 protocol are as follows:• Maximum line length per segment: 1200 meters (4000 feet)• Throughput of 10 Mbaud and beyond -Differential transmission(balanced lines) with high resistance against noise• Maximum 32 nodes per segment• Bi-directional master-slave communication over a single set oftwisted-pair cables• Parallel connected nodes, true multi-dropADAM-5000 systems are fully isolated and use just a single set oftwisted pair wires to send and receive! Since the nodes are connectedin parallel they can be freely disconnected from the host withoutaffecting the functioning of the remaining nodes.
