Black Box ACX1MT-AR KVM Extender Transmitter Upgrade Module - Analog Audio (Bi-Directional), RS232

The ACX1MT-AR is the transmitter-side upgrade card for a Black Box DKM modular KVM extender, and the counterpart to the ACX1MR-AR at the receiver. It adds bidirectional analog audio and an RS232 serial channel at the machine end of the link, so audio travels both ways and a serial control path reaches the host.

It is a modular card that seats in a slot of the DKM chassis, which means an installed extender can be given the capability in place. Connectors are analog audio and serial, bidirectional. Made in Germany.
