Summary Description:

Be sure to read the detailed description from the link below.
The DRA-SR-RJ45 is similar to the SignaLink™ USB with several major changes.
It doesn't have transformers, and is not galvanically isolated.
It has Hardware PTT for the quickest turn around (ACK/NAK) times.
"SR" models are based on our DRA-80 and is considered a "DRA Series" product.
It uses a high-quality reed relay, and its operation is nearly silent.
Works with the ICOM IC-706MKIIG, and other difficult to interface radios.
Adjustable VOX Delay of 0 up to 1.5 seconds is controlled from the front panel "DLY" potentiometer.
The radio connector is a female RJ45 - just like a SignaLink USB.
All LEDs, controls and connectors on the DRA-SR are located in the original locations. **
Multi-color power LED to indicate the operational status of the unit.
Jumper selectable attenuators for RX and TX audio level to help prevent overdrive with some radios.
Compatible with most SignaLink™ cables and "Plug-n-Play" jumper configuration modules (not included).
The circuit board is designed for low-noise and high signal to noise ratio.
Comes with 2 Allen wrenches - 3/32" for the end panels, and 1.5MM for the knobs.
REV2 boards now ship with a 3D printed rear panel and a 1/8" SPKR jack.
