2.4 Handshake Format Selection In order to ensure proper data transfers between the recorder and the host computer via the RS-232C interface, a mutual procedure is required for processing the electrical signals. Such a procedure is referred to as a ‘handshake’. Several handshake formats are available, with selection depending on the host computer being used. The same handshake format must be designated for both the recorder and the host computer.
2.4 Handshake Format Selection XON-DTR • Transmission data control • Reception data control • Reception data control CTS-DTR • Transmission data control • Reception data control IM DA100-11E : A hardware handshake status is established between the recorder and the host computer. The recorder will stop a data transmission if a ‘CTS=False’ status is established, and will resume the transmission when a ‘CTS=True’ status is established.
2.5 Communication Data Format The RS-232-C interface uses a START-STOP communication format. With this format, a START bit is placed at the beginning of each character transmitted, followed by the data bits, parity bit, and stop bit, in that order. (See the figure below.) ‘Line idle’ condition Return to ‘line idle’ condition (dotted line), or proceed to next data START bit.

3.3 RS-422-A/RS-485 Interface Connection The following explains how the RS-422-A/RS-485 module is connected to the computer.
3.3 RS-422-A/RS-485 Interface Connection Connecting to the Host Computer Can be connected to a host computer with RS-232-C, RS-422-A, RS-485 ports. • In the case of RS-232-C, a converter is used as shown in the diagram below. • For information on recommended converters, refer to “Converters” in the latter. • Dip switch needs to be changed depending on whether it is a two-wire system or four-wire system. Refer to “3.5 RS-422-A/RS-485 Interface Parameter Setting Procedure.
3.3 RS-422-A/RS-485 Interface Connection In the case of two-wire system Connect send and receive terminals with the same signal polarity on the terminal arrangement of the RS-422-A/RS-485 module. Only two wires are used in connecting to other units.
3.3 RS-422-A/RS-485 Interface Connection Converter Recommended converter : Sharp Z-101HE Caution Some converters other than the recommended, do not have the FG and SG terminals insulated. In such cases, do not connect as in the diagram on the previous page (do not connect anything to the FG and SG terminals of the converter). Especially when it is long distance, the potential difference may damage the devices or the communication may become unreliable.
3.3 RS-422-A/RS-485 Interface Connection Minimum Response Time Because send and receive are done on the same line in the two-wire system, minimum response time needs to be set. The minimum response time is the amount of time the RS-422-A/RS-485 module waits in order for the host computer to be able to receive the data after it sends data. The time can be set in the range from 0 to 100 ms.
3.4 Communication Data Format Same as the RS-232-C interface. For a description, refer to “2.5 Communication Data Format.
3.5 RS-422-A/RS-485 Interface Parameter Setting Procedure Setting of the RS-422-A/RS-485 parameters must be carried out using the 4 dip switches located next to the module connector.

Setting the Dip Switch You can select the following three modes by setting the dip switch. Configuration mode: A mode in which the IP address, subnet mask, and default gateway are set for theDA100.
4.3 Names and Functions of Each Section Warning If the STS2 LED is lit, there is a problem with the communication. You can check the details of the problem by displaying the communication status (see section 4.8 “Displaying the Communication Information”). Error An error occurs when the communication fails. When communication error or EEPROM error occurs, the DA100 must be repaired.
4.4 Setting the IP Address Before connecting to the network, you will set the IP address, subnet mask, and default gateway of the DA100. You will need the Data Acquisition Software 32 that came with the DA100 or the Data Acquisition Software 32 Plus that is sold separately. Connect the PC and the DA100 as shown below. The PC must have the Data Acquisition Software 32 or the Data Acquisition Software 32 Plus installed. Set the mode of the Ethernet module to configuration mode.
4.5 Connection Methods When Directly Connecting to the PC If you are directly connecting the DA100 and the PC to read in the measured data, connect them through a hub as follows. Ethernet module DC100 SCSI SUB UNIT I/F PC WARNING 100-240V AC 50/60Hz 130VA MAX FUSE 250V/T2.5A ETHERNET I/F 10BASE-T 4 MODEL STYLE SUFFIX Overview and Specifications of Ethernet Interface SUPPLY FREQUENCY NO.
4.6 Checking the Connection (Loopback test) Automatically tests the condition of the physical connection of the DA100 to the network. Mode Setting Set the dip switch of the Ethernet module to test mode (switch 1: OFF, switch 2: ON). Functions of the Ethernet module are suspended while in test mode. Therefore, it’s necessary to set the dip switch to communication mode after testing. Note • After testing, set the dip switch to communication mode and reboot the DA100.
4.7 Transferring the Instantaneous Values The instantaneous values of the data measured on the DA100 (current measured data) are transmitted to the PC that is connected through port No. 34151. Note • Up to four PCs can connect to port No. 34151 of one DA100. • The commands described here do not affect the status byte. • EF, EL, and EB commands do not suport sub-delimiters. The measured data are transmitted using the following command.
4.7 Transferring the Instantaneous Values The alarm status indicates two levels with one byte. Upper Byte Lower Byte Level2 Level1 1 byte Lower Byte Upper Byte Level4 Level3 1 byte D1 to Dn, H1 to Hn: Alarm status (level 3, 4) (No output when p1 is 0) Contents and format are the same as level 1 and 2. E1 to En: Fixed to 80H F1 to Fn: Computation channel number The measured/computed data are output in the order specified by the EB command.

App.1 Computing Equation DA100 can execute computations with the measured data of each input channel taken as a variable, and the results can be displayed/saved (functions available for use only when DA100 has the /M1 option) . The following operators can be used for computation. Basic operators Type Operator Example Description Addition + 001+002 Obtain the sum of the measured data of channel 001 and channel 002.
App.1 Computing Equation Statistical operators within the group Type Operator Example Description Maximum value CLOG.MAX() CLOG.MAX(G01) Obtain the maximum value of the measured data of group G01. Minimum value CLOG.MIN() CLOG.MIN(G02) Obtain the minimum value of the measured data of group G02. Max-min value CLOG.P-P() CLOG.P-P(G03) Total value CLOG.SUM() CLOG.SUM(G04) Obtain the total value of the measured data of group G04. Average value CLOG.AVE() CLOG.
App.1 Computing Equation Priority of operators The priority of operators in a computing equation is as follows. The operators are placed in order from the highest priority. Type Operators Function ABS(), SQR(), LOG(), LN(), EXP(), MAX(), MIN(), P-P(), SUM(), AVE(), PRE(), HOLD():, RESET(): Exponentiation ** Signs, logical negation +, -, NOT Multiplication, division *, / Addition, subtraction +, - Greater/less relation .GT., .LT., .GE., .LE. Equal/not equal relation .EQ., .NE.
App.1 Computing Equation - Control using the event/action function Can start/stop computations or clear/reset computed results by an event occurring. This function distinguishes clear and reset as shown below. - Clear Computed data When issued during the computation, the measured data is reset before doing the first computation.
App. 2 Report Function The DA calculates and processes an hour’s, day’s or month’s worth of measurement or computation data into instantaneous values, averages and/or sums. The results can be delivered using the communication function. Reports come in the following three types. • Hourly report Intervals Between Making Reports; Every hour (1:00, 2:00 . . .
App.2 Report Function Report Channels There are sixty report channels, from R01 to R60. You can assign channels for measuring objects being computed or computation channels and the type of computing on a report-channel basis. When making a report of computed data, let computing start before letting the report making start.
App.2 Report Function Starting/Stopping Report Making Report making can be started or stopped in two ways: • DR command • Use the event/action functions to define the start/stop of making a report for the following events: Edge action: You can define every event as an edge action to start/stop report making. Level action: You can use remote, alarm, relay signals as events to start/stop report making. Report making starts at the same time that any of these events occur.
App.2 Report Function Processing Against Absence of Measurement Measurement may not take place if the DA is loaded beyond its processing capability. If absence of measurement occurs, the DA compensates for the missing data with the data it measures immediately after recovering from the absence of measurement (the data for the period with no measurement thus match those acquired immediately after recovering from the absence of measurement).
