Input Connectors

The input connectors (Figure A–8) of the PowerLab 15T, 2/26, 4/26 and 26T are 8-pin DIN
connectors. They allow the connection of ADInstruments pods — small, low-cost signal
conditioners for specific tasks, for use with precalibrated transducers. Transducers
designed for direct connection can be provided with power and control through the
connectors.
The PowerLab 2/26 and 4/26 also have BNC input connectors as well as the 8- pin DIN
connectors.
Note that with the PowerLab 26T:

USB Connection

PowerLabs have a USB 2.0 port, and connect to a computer with USB ports or a PCI
USB card installed, allowing high data transfer rates to USB 2.0- compliant computers
(slower transfer to USB 1.1-compliant computers).
The signal must be transmitted in a certain time; in practical terms this means cables
between any USB devices, including hubs, must be no more than 5 meters (16 feet) in
length, and with hubs in the chain, devices must be no more than 30 meters (98 feet)
from the computer. For proper use and reliable results, the PowerLab needs a high-
speed connection. Your PowerLab is supplied with a high-speed USB cable. If you
replace the USB cable, buy a high-speed cable (fully shielded, twisted-pair and standard
USB connections: a Type A plug at one end and a Type B plug at the other).

• ADInstruments front-ends, such as the FE221 Bridge Amp, can be used with
inputs 1 and 2 (but not inputs 3 or 4) by connecting them with the DIN-to-BNC
adaptor.
• When an ADInstruments pod is connected to either input 3 or 4, the corresponding
Bio Amp input is turned off .
