If any of these items are missing or damaged, contact the supplier.•OMG-Ultra-485 Serial I/O Adapter• 3.5″ Serial Utility Diskette•User ManualFactory Default SettingsThe OMG-Ultra-485 factory default settings are as follows:Port #Base Address IRQ Electrical SpecificationPort 13F84RS-485 ‘Auto’To install the OMG-Ultra-485 using factory default settings, refer to Installation on page 10.For your reference, record installed OMG-Ultra-485 settings below: Port #Base Address IRQ Electrical SpecificationOmega Engineering OMG-Ultra-485Page 1Card SetupCard SetupThe OMG-Ultra-485 contains several jumper straps which must be set for proper operation.Address SelectionThe OMG-Ultra-485occupies 8 consecutive I/O locations, and looks to the PC as a standard serial port. A DIP-switch (SW1) is used to set the port address options for the OMG-Ultra-485. Be careful when selecting the port addresses as some selections may conflict with existing ports. The following table shows the addressing options available with the standard PAL. If different address options are required, please contact Omega Engineering Technical Support about a custom PAL option.Port1 J2SW1-1SW1-2SW1-3SW1-4 Disabled On On On On3F8On On On Off2F8On On Off On3E8On On Off Off2E8On Off On On3220On Off On Off3228On Off Off On4220On Off Off Off4228Off On On On238Off On On Off300Off On Off On308Off On Off Off280Off Off On On288Off Off On Off290Off Off Off On298Off Off Off Off Note: Each COM port in the system should have a unique address. Typically COM1: - COM4: addresses are 3F8, 2F8, 3E8 & 2E8 Hex.Omega Engineering OMG-Ultra-485Page 2Card SetupOmega Engineering OMG-Ultra-485Page 3IRQ SelectionHeader E1 selects the interrupt request for each serial port. If COM1: is selected, the corresponding jumper must be on the IRQ4 setting. If COM2: is selected, the corresponding jumper must be on IRQ3.Note : Most communications software applications default COM3: to IRQ4and COM4: to IRQ3. This requires the sharing of interrupts between COM1: and COM3:, and between COM2: and COM4:.While this is the default, it is not always the preferred setting.Check your software configuration instructions to determine the most appropriate IRQ selection .Figure 1 - Header E1, IRQ SelectionAny two or more ports can share a common IRQ by placing the jumpers on the same IRQ setting at header E1 and setting the appropriate selections at E2. Consult your particular software for IRQ selection. If no interrupt is desired, remove the jumper.2345710111215E1Card SetupOmega Engineering OMG-Ultra-485Page 4Interrupt ModesHeader E2 selects the interrupt mode for the OMG-Ultra-485.‘N ’ indicates the (N )ormal, single interrupt per port mode. ‘S ’ Indicates the (S )hared interrupt mode, which allows more than one port to access a single IRQ. Any two or more ports can share a common IRQ by placing the jumpers on the same IRQ setting and setting the appropriate selections at E1. Consult your particular software for IRQ selection. If no interrupt is desired, remove the jumper. ‘M ’ indicates the inclusion of a 1K ohm pull-down resistor required on one port when sharing interrupts.Figure 2 - Header E2, Normal IRQ ModeSet the jumper to ‘S ’ if you are using more than one OMG-Ultra-485 in a bus or to completely remove the pull-down resistor for hardware compatibility. Setting the adapter in this configuration when it is not accompanied by a pull-down resistor will prevent the ports from triggering an interrupt .Set the jumpers to ‘S ’ for shared interrupt mode on all blocks sharing an IRQ except one. Set that port block for ‘M ’. This provides the pull-down resistor circuit that makes sharing IRQs possible. If you are using more than one OMG-Ultra-485 or a compatible adapter in a bus you should only have one port set to ‘M ’. The following example shows two OMG-Ultra-485adapters sharing a single IRQ.Figure 3 - Header E2, Shared IRQ ModeCard Setup RS-485 Enable ModesRS-485 is ideal for multi-drop or network environments. RS-485 requires a tri-state driver (not dual-state) that will allow the electrical presence of the driver to be removed from the line. The driver is in a tri-state or high impedance condition when this occurs. Only one driver may be active at a time and the other driver(s) must be tri-stated. The output modem control signal R equest T o S end (RTS) is typically used to control the state of the driver. Some communication software packages refer to RS-485 as RTS enable or RTS block mode transfer.One of the unique features of the OMG-Ultra-485 is the ability to be RS-485 compatible without the need for special software or drivers. This ability is especially useful in Windows, Windows NT, and OS/2 environments where the lower level I/O control is abstracted from the application program. This ability means that the user can effectively use the OMG-Ultra-485 in a RS-485 application with existing (i.e. standard RS-232) software drivers.Header E5 is used to control the RS-485 mode functions for the transmitter circuit. The selections are ‘RTS’ enable, ‘Auto’ enable, or ‘422’ which means always enabled. The ‘Auto’ enable feature automatically enables/disables the RS-485 transmitter circuit. The ‘RTS’mode uses the ‘RTS’ modem control signal to enable the RS-485 transmitter circuit and provides backward compatibility with existing software products. The ‘422’ mode allows the port to be used in a point to point RS-422 application where the tri-stating of the transmitter circuit is not required.Note: The jumper in the above example is in the ‘422’ position. This is the only setting in which the modem control outputs (RTS, DTR) are valid.Omega Engineering OMG-Ultra-485Page 5Card Setup Figure 4 - Header E5 RS-485 Transmit ModeHeader E3 is used to control the RS-485 enable/disable functions for the receiver circuit. The RS-485 ‘Echo’ is the result of connecting the receiver inputs to the transmitter outputs. Every time a character is transmitted, it is also received. This can be beneficial if the software can handle echoing (i.e. using received characters to throttle the transmitter) or it can confuse the system if the software does not. The selection at E3 should follow the selection made at E5 if ‘No Echo’ is desired. If Echo suppression is not desired then leave the jumper in the ‘422’ position. Also note, the modem control inputs (DSR, DCD, CTS) are only valid when Header E3 is in the 422 mode. These header blocks are described in the illustration and table that follow.Figure 5 - Header E3 RS-485 Receive ModeOmega Engineering OMG-Ultra-485Page 6Card SetupOmega Engineering OMG-Ultra-485Page 7Connector Pin Assignments EIA-530DIP-shunt E4 selects the pin out for the DB-25 connector P3. With the 5position shunt in the EIA-530 mode, the ULTRA-485 complies with the EIA-530 pin out with the following signals supported:EIA-530E4SIO-485Figure 6 - Dip-shunt E4 (EIA-530 Mode)Signal Name Pin #Mode GND Ground 7RDB RX+Receive Positive 16Input RDA RX-Receive Negative 3Input CTSB CTS+Clear To Send Positive 13Input CTSA CTS-Clear To Send Negative 5Input DSRB DSR+Data Set Ready Positive 22Input DSRA DSR-Data Set Ready Negative 6Input DCDB DCD+Data Carrier Detect Positive 10Input DCDA DCD-Data Carrier Detect Negative8Input TDB TX+Transmit Positive 14Output TDA TX-Transmit Negative 2Output RTSB RTS+Request To Send Positive 19Output RTSA RTS-Request To Send Negative 4Output DTRB DTR+Data Terminal.

A 100 ohm resistor is across each RS-530/422/485 input in addition to a 1K ohm pull-up/pull-down combination that bias the receiver inputs. DIP-switch SW2 provides the ability to customize this interface to system requirements. Each switch position corresponds to a specific portion of the interface. If multiple OMG-Ultra-485adapters are configured in a RS-485 network, only the boards on each end should have switches T, P & P ON. Refer to the following table for each position’s operation:Name FunctionT Adds or removes the 120 ohm termination.P Adds or removes the 1K ohm pull-down resistor in the RS-422/RS-485 receiver circuit (Receive data only).P Adds or removes the 1K ohm pull-up resistor in the RS-422/RS-485 receiver circuit (Receive data only).L Connects the TX+ to RX+ for RS-485 two wire operation.L Connects the TX- to RX- for RS-485 two wire operation.T P P L LFigure 8 – SW2, Line TerminationOmega Engineering OMG-Ultra-485Page 9Installation Omega Engineering OMG-Ultra-485Page 10InstallationThe OMG-Ultra-485 can be installed in any of the PC expansion slots.The OMG-Ultra-485 contains several jumper straps for each port which must be set for proper operation.1.

Parity is a simple method of determining if a data bit has been lost or corrupted during transmission. There are several methods for implementing a parity check to guard against data corruption. Common methods are called (E)ven Parity or (O)dd Parity. Sometimes parity is not used to detect errors on the data stream. This is refereed to as (N)o parity. Because each bit in asynchronous communications is sent consecutively, it is easy to generalize asynchronous communications by stating that each character is wrapped (framed) by pre-defined bits to mark the beginning and end of the serial transmission of the character. The data rate and communication parameters for asynchronous communications have to be the same at both the transmitting and receiving ends. The communication parameters are baud rate, parity, number of data bits per character, and stop bits (i.e. 9600,N,8,1).3.9"5.0"4.2"Appendix F - Compliance Notices Omega Engineering OMG-Ultra-485Page 22Appendix F - Compliance NoticesFederal Communications Commission StatementFCC - This equipment has been tested and found to comply with the limits for Class A digital device, pursuant to Part 15 of the FCC Rules.

科莱科技 Model 485 自动范围微安表说明说明书
low-cost, highly sensitive, easy-to-use instrument. The 485 measures DC current on seven ranges covering 10 decades from 100fA to 2mA. The input can withstand overloads as high as 1000V (with 100k Ωlimiting resistor) for flexibility in a wide range of applications in test, research, and student labs. An analog output linearly converts the incoming current to voltage for hard copy output or lution. The REL button makes readings relative to the baseline (the reading prior to touching the button). The LOG button converts the display to the logarithm (base 10) of the absolute value of the measured current. Digital calibration is performed from the front panel or over the bus.A 100-point data store buffer collects and stores measurements at one of six automatic reading rates from three per second to one per hour, or manually with the STORE button. Minimum and maxi-mum readings are continuously updated at three per second in the data store mode.The addition of the Model 4853 IEEE-488 Interface to the 485 provides fully programmable com-puter control. For isolation from the power line or for portability, the 485 can be battery powered with the Model 1758 Rechargeable Battery Pack.A C C E S S O R I E S AVA I L AB L EOUTPUT OPTIONS 4853IEEE-488 Interface (485)CABLES 4801Low Noise BNC Input Cable,1.2m (4 ft)4802-10Low Noise BNC Input Cable,3m (10 ft), unterminated 4803Low Noise Cable KitADAPTER4804Male BNC to Female Triax Adapter RACK MOUNT KITS1010Single Rack Mount Kit 1017Dual Rack Mount KitPOWER 1758Rechargeable Battery Pack See page 235 for descriptions of all accessories.485 PicoammeterVOLTAGE BURDEN CAN CAUSE ERRORSAT ANY CURRENT LEVELThe voltage burden is the terminal voltage of an ammeter.Anideal ammeter will not alter the current flowing in a circuitwhen connected in place of a conductor.Thus,it must havezero resistance and therefore zero voltage burden.Digital multimeters use the shunt ammeter technique shownin Figure 1to measure current.The measurement method is todevelop a voltage across a sensing resistor.The resistor is cho-sen such that 200mV corresponds to the maximum currentreading on a selected range.The voltage burden specificationis the 200mV developed across the sensing resistor.Feedback picoammeters such as the 485 and Keithley elec-trometers use a technique in which the voltage burden is theinput voltage of an op amp,as shown in Figure 2.The output voltage of the op amp is precisely related to theinput current.Since input voltage is output voltage divided byop amp gain (typically 100,000),the voltage burden is onlymicrovolts.The maximum specified voltage burden of the 485is only 0.2mV.An example of the problems caused by high voltage burden isshown in Figure 3.In measuring the emitter current of a tran-sistor,the DMM causes a very significant error (200mV out of300mV) while the 485 voltage burden creates negligible error(0.2mV out of 300mV).Even though the basic measurement iswell within the range of a DMM,the 485 makes a more accu-rate measurement since,due to its low voltage burden,the 485is much closer to an ideal ammeter.485 PicoammeterMODEL 485ACCURACY NORMAL MODE(1 Year)ANALOG REJECTION MAXIMUM18°-28°C RISE TIME RATIO CONTINUOUS RANGE RESOLUTION±(%rdg + counts)*(10%–90%)(50 or 60Hz)INPUT** 2nA100fA0.4+ 460 ms70 dB350 V DC 20nA1pA0.4+ 160 ms70 dB350 V DC200nA10pA0.2+ 1 6 ms65 dB350 V DC 2µA100pA0.15+ 1 3 ms65 dB350 V DC 20µA1nA0.1+ 1 3 ms65 dB50 V DC200µA10nA0.1+ 1 1 ms65 dB50 V DC 2mA100nA0.1+ 1 1 ms55 dB50 V DC*When properly zeroed. **With no limiting resistance: 1000V DC with external 100kΩseries resistance.Ideal Ammeter:VBURDEN= 0= 0% error485:VBURDEN≤0.2mV≤0.07% errorDMM:VBURDEN≤200mV≤67% error INPUT VOLTAGE BURDEN:<200µV.RANGING:Manual or autoranging.AUTORANGING TIME:Average 250ms per range change.SETTLING TIME AT DISPLAY:<1 second to within 2 countson fixed range.CONVERSION PERIOD:300ms.TEMPERATURE COEFFICIENT (0°–18°C & 28°–50°C):±(0.1×applicable accuracy specification)/°C.MAXIMUM COMMON MODE VOLTAGE:30V rms, DC to 60Hzsine wave.ANALOG OUTPUT:Output Voltage:+1V = –10000 counts,except +100mV = –10000 counts on 2nA range.
