The Basic I/O 1 1-1(Vol.1) THE BASIC I/O: BASIC I/Os are a family of small, industria l grade, remote data acquisition and control systems which exchange data with a Host computer via a serial comm unications link. Controlled by a wide range of software running on a Host computer, Basic I/Os are located near the sensors and actuators.
The Basic I/O 1 1-2(Vol.1) A notable feature of the BASIC I/O is its ability to gather data and perform ranging and statistical operations on raw data before it is se nt to the Host. The Host can thus spend less time manipulating data and more time gather ing it.
The Basic I/O 1 1-3(Vol.1) ANALOG OUTPUTS: Analog output modules are 100% isolated. These self-sourcing m odules provide the voltage or current necessary to drive standard instrument ation loads.
The Basic I/O 1 1-4(Vol.1) DIGITAL INPUTS: Digital input modules detect the presence or absence of a field signal. Module types vary from AC to dry contact sense. Because the industry standard modules are optically isolated, the response time performance of digital input instructions can be limited by the delay in the input modules themselves.
The Basic I/O 1 1-5(Vol.1) DIGITAL OUTPUTS: Digital output modules, commonly referred to as so lid state relays, control external AC or DC power sources. A dry-contact (mechanical relay) with very low contact resistance is also available. Digital output instruction types are: Set outputs Can set individual or multiple outputs On or Off.
The Basic I/O 1 1-6(Vol.1) SYSTEM THROUGHPUT: Input data throughput is the time from beginning of the first character of an input instruction to the end of the last character of the response. The processing time of the Host computer will affect the effective throughput.
The Basic I/O 1 1-7(Vol.1) It should be noted that the values in th e preceding throughput tables and the following equations reflect only the communications overhead and inherent processing delay of the BASIC I/O equipment.
The Basic I/O 1 1-8(Vol.1) COMMUNICATION PROTOCOL: The BASIC I/O Communication Protocol is 100% comp atible with the Opto-22 Optomux™ protocol. This ASCII printable serial protoc ol uses a “speak-onl y-when-spoken-to” format where only the host can initiate an information exchange.
The Basic I/O 1 1-9(Vol.1) Available I/O Modules ANALOG INPUTS, 12 BIT ANALOG OUTPUTS, 12 BIT Frequency Voltage IIF10K-B Input 300Hz -10KHz OV1 Output 0-1V, self-sourcing IF2.
The Basic I/O 1 1-10(Vol.1) DIAGNOSTICS: To confirm internal operations and communications link integrity, a set of built-in diagnostics test key system functions each time power is applied. Diagnostics reduce both installation debugging and operation troubleshooting.
The Basic I/O 1 1-11(Vol.1) PRODUCT TEST Every BASIC I/O is burned-in at 70 °C while operating in a network for a period of 24 hours prior to shipment. Every analog I/O module is operated and tested while it’s ambient operating temperature is cycled over the specified operating range of 0°C to 60°C for a period of 24 hours.

Introduction 1 1-1(Vol.2) Overview BASIC I/O AD s are a family of small, industrial grad e, remote data acquisition and control systems which exchange data with a Host computer via a serial comm unications link. Controlled by a wide range of software running on a Host computer, BASIC I/O ADs are located near the sensors and actuators.
Introduction 1 1-2(Vol.2) I/O signal compatibility : BASIC I/O ADs use duTec I/O modules to match signa l requirements exactly. With a direct interface to sensors, no external signal conditioning is required. Furthermore, all duTec modules feature total electrical isolation, bot h module to logic and module to module.
Introduction 1 1-3(Vol.2) Protocol Compatibility : The BASIC I/O AD instruction set core complies 100% with that of the OPTO- 22 Optomux ™ . With this ASCII character , speak-only-when-spoken-to protocol, a Host transmits inquiry requests to the BASIC I/O AD to determine the status of its various process inputs.
Introduction 1 1-4(Vol.2) Available I/O functionality: Analog Input Functions Input value Determines signal levels, with 12 bits resolution 1 Offsets Input values can be software offset, with 12 bits resolution, over the module’s specified range. Gain/ Slope The amplitude of input values can be software multiplied by factors ranging from 0.
Introduction 1 1-5(Vol.2) Digital inputs Read Read the on or off of all inputs Pulse widths The duration of a single or total on/off time of consecutive pulses can be resolved to the nearest 0.00 seconds for a max total of 10.9 minutes, or 46.6 hours with multiplied resolution.
Introduction 1 1-6(Vol.2) Squarewave Can generate squarewaves w ith programmable On and Off periods. On and Off periods ha ve a base range from 0.01 to 2.56 seconds. Resolution can be further multiplied by a factor of 1-256 on a system wide basis. Re-triggering is available.
Introduction 1 1-7(Vol.2) Specifications Network Communications: duTec supports two standards for transmitting seri alized I/O data between the host computer and the BASIC I/O ADs at baud rates to 38,400.
Introduction 1 1-8(Vol.2) Available I/O Modules ANALOG INPUTS, 12 BIT ANALOG OUTPUTS, 12 BIT Frequency Voltage I F10K-B Input 300Hz-10KHz OV1 Output 0-1V, self-sourcing IF2.
Installation 2 2-1(Vol.2) I nstallation Mounting: BASIC I/O ADs come in 4, 8, and 16 channel versions . Figure 2-1 below shows the footprint of each Basic I/OAD. Using corner holes, the unit can be mounted with 4- #6 or #8 round head or pan head screws.
Installation 2 2-2(Vol.2) Power Wiring: Power connections are made at the 2 positi on terminal block located on the module board marked +5V and GND No.
Installation 2 2-3(Vol.2) Designing the Network In order for the BASIC I/O AD to share its data with the hos t computer, it must be linked via a serial connection. This link can be hard-wired using an RS-422 dual twisted pair or an RS- 485 single twisted pair connection where the wire run between devices is less than 5000 feet.
Installation 2 2-4(Vol.2) RS-422: Advantages: Easier to implement in software since host driver need not be controlled. Can be either Multidrop or Repeat. No turn-around delay required. Disadvantages: Requires five conductor wire instead of three. RS-485: Advantages: Needs only 3 wire conductor.
Installation 2 2-5(Vol.2) RS-485 Programming : The BASIC I/O AD will work equally well when connect ed as RS-422 or RS-485. However special host programming considerations may be necessary when implementing an RS-485 network.
Installation 2 2-6(Vol.2) This interaction is heavily dependant on asynch ronous timing. Usually, the Host software has no real means of determining that the instruction has been completely sent. This means that the program must calculate the approximate tim e necessary to transmit the entire instruction before the RS-485 driver is disabled.
Installation 2 2-7(Vol.2) Network load V.S. Noise suppression: In order to improve RS-485 Bus noise immunity , particularly under tri-state conditions, a pair of “Network Bias Resistors” have been installed in each BASIC I/O AD unit. This design feature has been implemented in order to sa tisfy the majority of our customers.
Installation 2 2-8(Vol.2) Network Ty pe Switches Based upon the selected network configuration, each BASIC I/O AD must be setup before communications can begin. This is done with the network sw itches shown in figure 2-3. Figure 2-3 BASIC I/O AD Connectors, Switches an d Indicators .
Installation 2 2-9(Vol.2) The three basic communication connections for individual BASIC I/O ADs are: Repeat Used in RS-422 networks to extend range to 5000 feet between units. Sequential Display reads L1 Multidrop Used in RS-422 or RS-485 networks. Provides a total network range of 5000 feet.
Installation 2 2-10(Vol.2) Communications Wiring Host to BASIC I/O AD -RS-422: Figure 2-7 RS-422 Host to BASIC I/O AD Figure 2-7 shows two individually shielded twis ted pairs of AWG 24. Each pair has a ground wire connected to its shield. These drain wires are then connected to the signal grounds at each unit.
Installation 2 2-11(Vol.2) RS-485 Host to BASIC I/O AD: Figure 2-8 RS-485 To-BASIC I/O AD Figure 2-8 shows two individually shielded twis ted pairs of AWG24. Each pair has a drain wire connected to its shield. These drain wires are then connected to the signal grounds at each unit.

Each pair has a drain wire connected to its shield. These drain wires are then connected to the signal grounds at each unit.
Installation 2 2-13(Vol.2) BASIC I/O AD to BASIC I/O AD RS - 485 Figure 2-8 RS-485 BASIC I/O AD to BASIC I/O AD Figure 2.8 shows one individually shielded twis ted pair of AWG 24. Each pair has a ground wire connected to its shield. These drain wires are then connected to the signal grounds at each unit.
Installation 2 2-14(Vol.2) Installing the I/O modules: Certain guidelines must be followed when installing I/O modules on the BASIC I/O AD Chassis. In particular the analog modules mu st be grouped separately from the digital modules on each I/O chassis.
Installation 2 2-15(Vol.2) Module Wiring Analog Inputs: Modules should NEVER Be installed or removed while power is applied to the BASIC I/O AD . Following insertion in their respective sock ets, modules should be secured with the captive screw.

Installation 2 2-17(Vol.2) Analog outputs: Modules should NEVER be installed or removed while power is applied to the BASIC I/O AD. Note: Analog modules run hot to the touch . Both voltage and current output modules pr ovide their own isolated power output.
Installation 2 2-18(Vol.2) Digital Inputs: Modules should never be installed while power is applied to the BASIC I/O AD . With the exception of IDC5S digital input modul es, input sensing current fomes from a source external to the BASIC I/O AD . IDC5S input modules provide their own current for sensing contact closures.
Installation 2 2-19(Vol.2) Digital Outputs: Modules should NEVER be installed or re moved while power is applied to the BASIC I/O AD . The power for ODC5, ODC5A, OAC5, and OAC5A digital output modules comes from a source external to the BASIC I/O AD.
Setup 3 3-1(Vol.2) Chassis Setup Figure 3-17 Connectors, Switches, and I ndicators During the setup phase of a BASIC I/O AD system, the chassis is given specific values for unit address, analog/ digital separator, ne twork baud rate, and protocol pass type.

Function Address Sequential Display Master Unit Control MC 00h (0) UO=00 Master Unit Digital I/O MD 40h (64) U1=40 Master Unit Analog I/O MA 80h (128) U2=80 The OFFSET addressing mode is more convenient to use as only one address setup is required for each network connection.
Setup 3 3-3(Vol.2) Baud Rates: Any One of the standard baud rates of 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 can be used for the serial network communications . The sequential display indicates the letter H followed by the baud rate divided by 100.
Setup 3 3-4(Vol.2) Changing Setup Parameters Via P ushbutton: During setup the user may need to change the un it address, serial link, baud rate, and protocol pass type. The pushbutton located under the rem ovable cover is used to change these parameters.
Setup 3 3-5(Vol.2) The display continues to cycle through this sequence until there is a full cy cle with no changes. The BASIC I/O AD then stores all values in EEPROM for automatic use following the next power cycle.
Setup 3 3-6(Vol.2) Hardware error codes: When the BASIC I/O AD is initially turned on it goes through internal self testing. If anything is not correct, the appropriate error code will flash on the sequential display. Try cycling power, if that does not resolve the error condition please call duTec technical support at 800-248-1632.
