Introducing the RedLab 3105
Overview: RedLab 3105 features
This user's guide contains all of the information you need to connect the RedLab 3105 to your computer and to
the signals you want to control. The RedLab 3105 is part of the Meilhaus Electronic brand of USB-based data
acquisition products.
®
The RedLab 3105 is a USB 2.0 full-speed device that is supported under popular Microsoft
operating systems. The RedLab 3105 is fully compatible with both USB 1.1 and USB 2.0 ports.
The RedLab 3105 provides 16 channels of analog voltage output, eight digital I/O connections, and one 32-bit
event counter.
The RedLab 3105 has four quad (4-channel) 16-bit digital-to-analog converters (DAC). You set the voltage
output range of each DAC channel independently with software for either bipolar or unipolar. The bipolar
range is ±10 V, and the unipolar range is 0 to 10 V. The analog outputs may be updated individually or
simultaneously. A bidirectional synchronization connection allows you to simultaneously update the DAC
outputs on multiple devices.
Windows®
The RedLab 3105 features eight bidirectional digital I/O connections. You can configure the DIO lines as
input or output in one 8-bit port. All digital pins are floating by default. A screw terminal connection is
provided for pull-up (+5 V) or pull-down (0 volts) configuration.
The 32-bit counter can count TTL pulses.
The RedLab 3105 is powered by the +5 volt USB supply from your computer. No external power is required.
All I/O connections are made to the screw terminals located along each side of the RedLab 3105.

Digital I/O control terminal (DIO CTL) for pull-up/down configuration
All digital pins are floating by default. When inputs are floating, the state of unwired inputs are undefined (they
may read high or low). You can configure the inputs to read a high or low value when they aren’t wired. Use
DIO CTL connection (pin 54) to configure the digital pins for pull-up (inputs read high when unwired) or
the
pull-down (inputs read low when unwired).

Synchronous DAC load terminal (SYNCLD)
The synchronous DAC load connection (pin 49) is a bidirectional I/O signal that allows you to simultaneously
update the DAC outputs on multiple devices. You can use this pin for two purposes:
Configure as an input (slave mode) to receive the D/A LOAD signal from an external source.
When the SYNCLD pin receives the trigger signal, the analog outputs are updated simultaneously.
SYNCLD pin must be logic low in slave mode for immediate update of DAC outputs
When the SYNCLD pin is in slave mode, the analog outputs can be updated immediately or when a positive
edge is seen on the SYNCLD pin (this is under software control.)
The SYNCLD pin must be at a low logic level for DAC outputs to update immediately. If the external source
supplying the D/A LOAD signal is pulling the SYNCLD pin high, no update will occur.
Refer to the "RedLab-3100 Series" section in the Universal Library User's Guide for information on how to
update DAC outputs immediately.
Configure as an output (master mode) to send the internal D/A LOAD signal to the SYNCLD pin.
15
Page 16
RedLab 3105 User's Guide Functional Details
You can use the SYNCLD pin to synchronize with a second RedLab 3105 and simultaneously update the
DAC outputs on each device. Refer to the "Synchronizing multiple units
" section on page 16.
Use InstaCal to configure the SYNCLD mode as master or slave. On power up and reset the SYNCLD pin is
set to slave mode (input).
Refer to the "RedLab-3100 Series" section in the Universal Library User's Guide for information on how to
configure the RedLab 3105 with the Universal Library.
Counter terminal (CTR)
The CTR connection (pin 52) is the input to the 32-bit event counter. The internal counter increments when the
TTL levels transition from low to high. The counter can count frequencies of up to 1 MHz.
Power terminal (+5V)
The +5 V connection (pin 56) draws power from the USB connector. This terminal is a +5V output.
Caution! The +5V terminal is an output. Do not connect to an external power supply or you may damage
the RedLab 3105 and possibly the computer.
Synchronizing multiple units
You can connect the SYNCLD terminal pin (pin 49) of two RedLab 3105 units together in a master/slave
configuration and simultaneously update the DAC outputs of both devices. Do the following.
Chapter 1 Connect the SYNCLD pin of the master RedLab 3105 to the SYNCLD pin of the slave RedLab 3105.
Chapter 2 Configure the SYNCLD pin on the slave device for input to receive the D/A LOAD signal from the master
device. Use InstaCal to set the direction of the SYNCLD pin.
Chapter 3 Configure the SYNCLD pin on the master device for output to generate an output pulse on the SYNCLD
pin.
Set the Universal Library
for information on how to configure the RedLab 3105 with the Universal Library.
When the SYNCLD pin on the slave device receives the signal, the analog output channels on each device are
updated simultaneously.

Note 2: The duration of this particular output transient is highly dependent on the enumeration process of the
host PC. Typically the output of the RedLab 3105 is stable after 2 seconds.
Note 3: The maximum differential non-linearity specification applies to the entire 0 to 70 °C temperature range
of the RedLab 3105. This specification also accounts for the maximum errors due to the software
calibration algorithm (in Calibrated mode only) and the DAC8554 digital to analog converter nonlinearities.
