DX Engineering Transceiver to Amplifier Interface Cables

DX Engineering Transceiver to Amplifier Interface Cables support automatic band changing using band data, TTL or serial data, and are used to connect specific amplifier models to many modern transceivers. These cables have specially wired connectors to provide transceiver frequency information or general band data to the amplifier for automatic band changing. Most do not have a PTT amplifier keying line. Cables must be selected by amplifier model and transceiver brand and model:

DXE-OMAUTO-RS232 connects OM Power Automatic Tuning Amplifiers to transceivers with RS-232C CAT or COM ports, including Yaesu, TenTec, Elecraft and Kenwood (FlexRadio requires additional serial USB adapter).

DXE-2000 series cables are only for the Acom 2000A models

DXE-ACOMSS series cables are only for Acom Solid State 2020S, 1200S, 700S, 500S and legacy 600S (replacing original DXE-600 series cables).

DXE-ACOMSS-101,
DXE-ACOMSS-YSU10 and
DXE-ACOMSS-YSU8 cables carry PTT keying as well as Band Data, but they do not support Acom 04AT, 06AT or 20AT Tuner automatic operations, which require DXE-ACOMSS-YSU.

Most interface cables carry only CI-V, CAT or COM frequency data, but not transceiver PTT to amplifier keying signal (ground on transmit).
Automatic band-changing amplifiers that are interfaced with frequency data cables require a separate keying line. These have either a special connector to a male RCA, or are a standard male RCA phono patch cable, to handle PTT keying from the transceiver.
