SCSI III Pinout Notes (Apply to the preceding table.) Note 1: AOUT 1 (DAC1) applies to DaqBoard/500 only. The clock source of the secondary DAC1 channel may be software command, DAC1 Pacer clock, or Channel 0 clock source. Likewise, the return line (ARET 1) only applies to the DaqBoard/500. - Page 20 Clocks, Triggers, Counters, and Timers ADCLKIN – Uses pin #2 or pin #5. ADCLKIN is the ADC External Pacer Clock Input. This input recognizes TTL level signals and is edge sensitive. The active edge is selectable as either rising or falling. The ADCLKIN signal connection can be made at either pin #2 or pin #5, but NOT both at the same time.
- Page 21 DACLKIN/CNTR1 – Uses pin # 1 or pin # 39 for one of the following two functions. DACLKIN is the External DAC Pacer clock input. This input recognizes TTL level signals and is edge sensitive. The active edge is selectable as either rising or falling. CNTR1 is the general purpose Counter 1 clock input.

Page 22: Tb-100 Terminal Connector Option
TB-100 Terminal Connector Option The TB-100 Terminal Connector option can be used to connect all signal I/O lines that are associated with a DaqBoard/500 or /505. TB-100 can connect to either board’s 68- pin SCSI III connector via a 3 ft., 68-conductor cable (CA-55 or the shielded CA-56); or via a 6 ft. -

TB-100 Notes (Apply to the preceding table.) Note 1: Digital Common Pins on the SCSI III connector are: 35, 36, and 40. Note 2: Analog Common Pins on the SCSI III connector are: 24, 27, 29, 32, 59, 64, and 67. Note 3: References are not provided for DaqBoard/500 Series devices. - Page 24 Signal Types Floating Sources A Floating Source is a signal that has no connection to the building's power ground. Examples of Floating Sources are thermocouples, batteries and battery powered devices, and signals from optically isolated devices. When connecting Floating Sources to a data acquisition board, the ground reference of the signal must be tied to the analog ground (AGND) in order to establish a common reference point.
- Page 25 Differential (DIFF) In installations where each Ground Referenced Source signal has a local ground [signals located remote from one another] the Differential configuration must be used. Since the Differential configuration only responds to the difference in a signal between its high and low voltages, any Common Mode Voltage will be cancelled out. In addition, Differential configuration provides the best performance of the two configurations in an electrically noisy environment.
- Page 26 Differential for Floating Signal Sources Floating Signal Sources are typically wired to a data acquisition board in Single-Ended configuration. However, when the Floating Source signal leads pass through an electrically noisy environment, Differential configuration will give the best performance. When wiring Floating Signal sources in Differential configuration, a resistor can be connected from the low side of the sources to analog ground (AGND).

Page 27: Configuration
Configuration Configuration through Software DaqBoard/500 Series boards have no hardware jumpers or switches. All data-acquisition settings such as analog input, data collection rates, input voltage range, and operating modes are configured through application software. A DaqView software driver provides an application level software interface to Windows NT, 2000, and XP. -
Page 28: Dac Ranges
DAC Ranges The output range of the DaqBoard/500 DACs [DAC0 and DAC1] can be independently set to either ±10 V, or 0 to 10 V. The following table indicates the maximum resolution for each range. Note that resolution is not accuracy. Resolution defines the minimum definable voltage increment. -

Page 31: Theory Of Operation
Theory of Operation Process Definitions In order to best understand how to operate the various board functions, it is important to first understand the language that will be used to describe the board processes. The following is a list of pertinent terms and definitions used in this document. - Page 32 ADC and DAC Trigger This is the signal or impetus that initiates or terminates an Acquisition. Essentially the Trigger Starts or Stops the ADC or DAC PACER Clock. ADC Channel Configuration RAM Configuration lookup table. The length of this table can be anywhere from 1 element to 176 elements. When an ACQUISITION is in process, the board will sequentially go through this list to determine the channel and gain setting for the next conversion.
- Page 33 Starting (Triggering) an ADC Acquisition There are several methods that can be used to initiate an acquisition, all of these are achieved by triggering or gating the ADC clock as mentioned previously. Note that a trigger is an edge active event and a gate is a level controlled enable.
- Page 34 Stopping an ADC Acquisition (CLOCK) Typical ways of halting an acquisition involve use of one of the following: Software External Gate (ADTRGIN) External Trigger (ADTRGIN) ADC Software The acquisition can be stopped by software control. ADC External Gate An ADC clock may also be “switched off” with the external trig/gate input (ADTRGIN). Refer to the section entitled ADC External Gate (on page 4-5 ) for additional information about this mode.
- Page 35 Clocking the DAC The DaqBoard/500 includes two DAC channels. The clock source of the primary DAC0 channel may be any of the following: DAC0 Pacer Clock External Event (DACLKIN). The clock source for the secondary DAC1 channel is limited to the following sources: DAC1 Pacer Clock Channel 0 Clock Source.

Analog-to-Digital A circuit or device that converts analog values into digital values, such as binary bits, for use in Converter (ADC) digital computer processing.
- Page 44 Differential mode Differential mode voltage refers to a voltage difference between two signals that are referenced voltage to a common point. Example: Signal 1 is +5 VDC referenced to common. Signal 2 is +6 VDC referenced to common. If the +5 VDC signal is used as the reference, the differential mode voltage is +1 VDC (+ 6 VDC - +5 VDC = +1 VDC).
