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 US Digital's QSB and USB4 interface products.
The corresponding receiver, EA-R-L-10-W5 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). The single-ended 5-pin output side has five wires.
Single-ended Cable Driver
The EA-D-H-5- driver converts the single-ended A/B/I output from USD’s incremental encoders (or any 3 TTL level signals) to 3 digital outputs with a large voltage swing proportional to the power supply voltage. The power supply voltage range is 7.5 to 30VDC. The EA-D-H-5- allows 5V encoders to be used in high voltage applications. The output side of the driver is a 5-pin male latching connector (FH5). Various connector options are available on the 5-pin input side.
US Digital can supply nearly any cable to your specifications. See the Cables & Connectors page for more information.

DRIVER (EA-D-) PINOUT
The driver input is a 4-pin or 5-pin connector. See "Connector B Options" for pictures of the available connectors.
The output connector is a 5-pin latching connector, FH5 (TE # 2-103634-7), or a 10-pin latching connector, FH10 (MOLEX# 74162-2010).

Notes:
(1) For the EA-D-L-10, the +5VDC pins on the input and output connectors are electrically connected together, so power can be applied to either the input or output connector. For the EA-D-H-5, the 7.5 to 30VDC power is applied at the OUTPUT connector. +5V out is generated at the INPUT connector.
RECEIVER (EA-R-) PINOUT
The receiver input is a 10-pin latching connector, FH10 (MOLEX# 74162-2010). The output has five 12" discrete wires (W5).
