The UE9 series was the first LabJack product to incorporate industrial strength Ethernet, and offers customers a wide range of capabilities. It has a long service record of reliability and customer satisfaction.
New applications should consider the newer T7 or T7-Pro over the UE9 or UE9-Pro. The T7 family is generally superior at a lower price.
- The LabJack UE9 has 14 external analog inputs (AIN0-AIN13). AIN0-AIN3 are available on screw terminals and also on the DB37 connector. All 14 analog
inputs are available on the DB37 connector.
- Each analog input can be configured individually as unipolar (four ranges from 0-5 volts to 0-0.625 volts) or bipolar (5 volts). Analog input resolution
is 12-bits at max speed (12 us conversion time), increasing up to 16-bits at slower speeds (2.7 ms conversion time).
- Command/response (software timed) analog input reads typically take 1.5+ ms depending on number of channels and communication configuration. Hardware
timed input streaming has a maximum rate that varies with resolution from 250 samples/s at 16-bits to 50+ ksamples/s at 12-bits.
- The LabJack UE9 has 2 analog outputs (DAC0 and DAC1) that are available both on screw terminals and the DB37 connector. Each analog output can be set
to a voltage between 0 and 4.9 volts with 12-bits of resolution. The analog outputs are based on a true voltage reference.
- The analog outputs are updated in command/response mode, with a typical update time of 1.5-4.0 ms depending on communication configuration.
- The LabJack UE9 has 23 digital I/O channels which can be individually configured as input, output-high, or output-low. 8 of these lines are called flexible
digital I/O (FIO) and can be software configured as up to 6 timers and 2 counters.
- The first 4 FIO are available on screw terminals and the DB37 connector. All 8 FIO and 3 MIO are available on the DB37 connector, and 8 EIO and 4 CIO
are available on the DB15 connector.
- Command/response (software timed) reads/writes typically take 1.5-4.0 ms depending on communication configuration. The digital inputs can also be read
in a hardware timed input stream where up to 16 inputs count as a single stream channel.
- Up to 6 FIO can be configured as timers. The timers are very flexible, providing options such as PWM output, pulse timing, pulse counting, and quadrature
- Up to 2 FIO can be configured as 32-bit counters.
- All I/O lines on the UE9 are protected against minor overvoltages. The AIN lines can withstand continuous overvoltage of +/- 15 volts, the FIO lines
can withstand up to 10 volts, while the EIO/CIO/MIO lines can withstand up to 6 volts.
- Power can be provided by the USB cable or an external 5 volt supply (included). When only Ethernet is connected, and an isolated power supply is used
(such as the included wall-wart), the entire UE9 is electrically isolated.
High Channel Count Applications:
- By using USB hubs or Ethernet switches, many LabJacks can be interfaced to a single PC, providing an inexpensive solution for low-speed high channel
- Modbus is an industry standard command/response protocol for data acquisition and control equipment. The UE9 supports Modbus/TCP in hardware, so any
software that supports Modbus/TCP can talk to the UE9 with no further software/drivers required.
Wireless Data Acquisition:
- Combining the UE9 with a standard 802.11 wireless Ethernet bridge or access point ($50-$200 from any computer retailer) provides inexpensive wireless
data acquisition. Applications include high-speed continuous wireless data acquisition, long distance remote sensing and control, or PDA based data
