EA Product Description
Differential Cable Driver/Receiver
The EA-D-L-10- is a differential RS-422 cable driver which converts the single-ended A/B/I output from USD's single-ended incremental encoders (or any three TTL level digital signals) to 3 pairs of differential signals. This allows the encoder to drive long cables (up to 1000 ft.) and reduces false switching in noisy environments. Various connector options are available on the 5-pin input side of this adapter. The output differential signals are available on a male 10-pin latching connector (FH10). The differential signal from the EA-D-L-10- can be connected directly to USD's QSB and USB4 interface products.
The corresponding receiver, EA-R-L-10- converts the received differential signals back to 3 single-ended TTL level digital signals. The differential input side of the receiver is a 10-pin male latching connector (FH10). Various connector options are available on the single-ended 5-pin output side.
The EA-D-H-10- is the same as the EA-D-L-10-, but offers a wide operating voltage range of 7.5 to 30VDC and a large output voltage swing proportional to the power supply voltage. This adapter allows 5V encoders to be used in high voltage applications.
Single-ended Cable Driver
The EA-D-L-5- driver converts 3 single-ended, low drive digital signals to 3 single-ended, high current drive digital signals. This variant is useful since the TTL outputs of some incremental encoders can sink (pull-down) just under 4mA and source (pull up) only about 200 uA. The output side of the driver is a 5-pin male latching connector (FH5). Various connector options are available on the single-ended 5-pin input side.
The EA-D-H-5- is the same as the EA-D-L-5-, but offers a wide operating voltage range of 7.5 to 30VDC and a large output voltage swing proportional to the power supply voltage. The EA-D-H-5- allows 5V encoders to be used in high voltage applications.
US Digital can supply nearly any cable to your specifications. See the Cables & Connectors page for more information.

DRIVER (EA-D-) PINOUT
For a Driver, the input connector is a 4-pin or 5-pin connector chosen from: H5, FH5, C5, FC5, LC5, MIC4, W5. See "4-pin, 5-pin Connector Options" for pictures of the available connectors.
The output connector is either a 5-pin latching connector (FH5) or a 10-pin latching connector (FH10).

Notes:
(1) For the Low voltage (EA-D-L-) versions, the +5VDC pins on the input and output connectors are electrically connected together, so power can be applied on either the input or output connector. For the High voltage (EA-D-H-) versions, the 7.5 to 30VDC power is applied at the OUTPUT connector. +5V out is generated at the INPUT connector.
RECEIVER (EA-R-) PINOUT
For a Receiver, the input connector is always a 10-pin latching connector (FH10). The output connector is a
5-pin connector chosen from: H5, FH5, C5, FC5, LC5, W5. See
"4-pin, 5-pin Connector Options" for pictures of the available connectors.
