The USB-3100 Series includes the following hardware:
The USB-3100 Series supports the following features.
Functions
UL: cbAOut(), cbAOutScan(), cbVOut()
UL for .NET: AOut(), AOutScan(), VOut()
Python for Windows: a_out(), a_out_scan(), v_out()
Options
SIMULTANEOUS (cbAOutScan() / AOutScan() / a_out_scan() only)
HighChan
USB-3101, USB-3102, and USB-3110: 0 to 3
USB-3103, USB-3104, and USB-3112: 0 to 7
USB-3105, USB-3106, and USB-3114: 0 to 15
Count
HighChan – LowChan + 1 max
Rate
Ignored
Range
Range is not programmable, and is set either with InstaCal or with the API – cbSetConfig() with BIDACRANGE when using the UL, SetDACRange() when using the UL for .NET, and set_config() with DACRANGE when using Python.
Range is ignored by cbAOut().
The Range value must be specified when using cbVOut()/VOut(), v_out(), as this function is not compatible with current output ranges.
DataValue
0 to 65,535 (Refer to 16-bit values using a signed integer data type for information on 16-bit values using unsigned integers.)
Configuration
Functions
UL: cbDConfigBit(), cbDConfigPort()
UL for .NET: DConfigBit(), DConfigPort()
Python for Windows: d_config_bit(), d_config_port()
PortNum
AUXPORT
PortType
AUXPORT
Port I/O
Functions
Python for Windows: d_in(), d_out()
PortNum
AUXPORT
DataValue
0 to 255 for AUXPORT
Bit I/O
Functions
UL: cbDBitIn(), cbDBitOut()
UL for .NET: DBitIn(), DBitOut()
Python for Windows: d_bit_in(), d_bit_out()
PortType
AUXPORT
BitNum
0 to 7 on AUXPORT
Functions
UL: cbCClear(), cbCIn()*, cbCIn32(), cbCLoad(), cbCLoad32()**
UL for .NET: CClear(), CIn()*, CIn32(), CLoad(), CLoad32()**
Python for Windows: c_clear(), c_in()*, c_in_32(), c_load()**, c_load_32()**
*Although cbCIn()/CIn()/c_in() are valid for use with this counter, cbCIn32()/CIn32()/c_in_32() may be more appropriate, since the values returned may be greater than the data types used by cbCIn(), CIn(), and c_in() can handle.
**cbCLoad()/cbCLoad32(), CLoad()/CLoad32(), and c_load()/c_load32() only accept Count=0. These functions are used to reset the counter.
CounterNum
1
Count
232-1 when reading the counter.
LoadValue
0 when loading the counter.
cbCLoad() and cbCLoad32() / CLoad() and CLoad32()are only used to reset the counter for this board to 0. No other values are valid.
The Basic signed integers guidelines in the Digital Input/Output Hardware topic apply when using cbCIn() or CIn() for values greater than 32,767 and when using cbCIn32() or CIn32() for values greater than 2,147,483,647.
RegNum
LOADREG1
Functions
UL: cbFlashLED()
UL for .NET: FlashLED()
Python for Windows: flash_led()
Causes the LED on a USB device to blink. When you have several devices connected, use this function to identify a particular device.
This hardware supports device detection with the API. Refer to the InstaCal, API Detection, or Both? section for information about whether to use InstaCal or the API to detect and configure hardware.

The SIMULTANEOUS scan option can only be used with cbAOutScan() / AOutScan() / a_out_scan().
Set the direction of the SYNCLD pin (pin 49) with the Simultaneous Mode option in InstaCal to be either Master (output) or Slave (input).
When you do not specify SIMULTANEOUS, the analog outputs are updated in sequential order, and the SYNCLD pin is ignored.
The voltage outputs on the USB-3110, USB-3112, and USB-3114 incorporate high-drive current output capability. The high drive current outputs allow each of the voltage outputs to sink/source up to 40 mA (maximum) of load current.
The voltage outputs should not be kept in a short-circuit condition for longer than the specified 100 ms. For those applications that may potentially exceed the 40 mA maximum current limit or the 100 ms short-circuit condition, external current limiting must be used to prevent potential damage to the USB-3110.
Each voltage output channel on the USB-3102, USB-3104, USB-3106 has an associated current output channel. The voltage and current outputs are grouped as channel pairs. Each D/A converter output controls a voltage and current channel pair simultaneously. When you write to a voltage output, its associated current output is also updated.
Each voltage/current channel pair can be updated individually or simultaneously. Leave each pair of unused voltage and current outputs disconnected.
