Using T-Cables
CAUTION CAUTION CAUTION CAUTION
Turn power OFF to the Daq devices and externally connected equipment while
connecting cables and setting configuration jumpers and switches or before opening
the lid. Electrical shock or damage to equipment can result even under low-voltage
conditions.
A T-Cable is a ribbon cable that extends the connections of one of the ports it plugs into, thus allowing a
second cable to plug into that port. The following figure clarifies the concept.
T-Cables are available in different lengths and can be used for linking two or more compatible devices
together via the device’s 37-pin digital I/O connectors.
The bottom-end of the T-Cable is a dual-connector, consisting of both a female connector, and a 37-pin
(male) connector. As seen in the following illustration, the T-Cable’s 37-pin (male) connector can be used
for “Daisy-Chain” applications.
Each T-Cable comes with three sets of screws. These are designated (in the diagram) as: short, medium, and
long. Use the short screws to secure the single, female-end of the cable to the device; and use the medium
length screws to secure a cable’s “dual-end” connector. Use the long screws for daisy-chain applications
(when you are connecting one T-Cable to another T-Cable).
Tighten screws snug only; do not over-tighten!
