SKY COMMAND SYSTEM II

The SKY COMMAND SYSTEM II allows remote control of a TS-990S, TS-2000, TS-2000X, TS-B2000, TS-480HX, TS-480SAT, TS-
570D, TS-570S, TS-590S, or TS-870S HF transceiver.
You will use one transceiver as a control station called “Commander”. The transceiver connected with the HF transceiver is called
“Transporter”. It will function as an interface between the Commander and the HF transceiver. This system allows you, for example, to
watch for and hunt DX while washing your car, or to operate the HF transceiver while relaxing in your car, living room, or patio, instead
of in your shack.
The Commander and Transporter transfer audio and commands as below:

CONNECTING THE TRANSPORTER WITH THE HF TRANSCEIVER

In order to connect the transporter to the HF transceiver, you need to prepare three cables by yourself. For the connection between the
PC/ COM connectors on the two transceivers, you may use a commercially available RS-232-C cross-wired cable (A D-SUB female/
male conversion adapter is required.)
Note:
◆ Operation of SKY COMMAND SYSTEM II may not been permitted in certain countries. Check your local laws before operating.
◆ Switch OFF both the Transporter and HF transceiver before making the connection.
◆ The Transporter automatically transmits its callsign in Morse at regular intervals because of legal requirements; therefore, transmit side tone must be output from the
HF transceiver.
◆ When the Transporter is too close to the HF transceiver, unwanted feedback may cause malfunction.
◆ Do not share a regulated power supply between the Transporter and the HF transceiver. Unwanted feedback may cause malfunction.
