15 CONNECTING PERIPHERAL EQUIPMENT RTTY EQUIPMENT Use the ACC 2 connector to connect to the RTTY equipment. Connect the RTTY key output line to pin 2 of the ACC 2 connector. Connect the demodulation input line of the RTTY equipment to pin 3 of the ACC 2 connector. Note: Do not share a single power supply between the transceiver and the RTTY equipment. Keep as wide a separation as possible between the transceiver and the RTTY equipment as practical to reduce noise-pickup by the transceiver. MCP power supply MCP Personal computer/ dumb terminal TS-570 ACC 2 LINEAR AMPLIFIER Connect an external transmit power amplifier to the REMOTE connector. Before using the external amplifier, switch ON the linear amplifier control relay via Menu No. 39. The TX/RX relay response time is 10 ms when you have selected CW Full Break-in and 25 ms when you have selected CW Semi Break-in. Note: The TX/RX control method differs depending on external amplifier models. Some amplifiers enter the TX mode when the control terminal is grounded. For those amplifiers, connect pin 2 of the REMOTE connector to the GND terminal of the amplifier and connect pin 4 of the connector to the control terminal of the amplifier.

ANTENNA TUNER Use the ANT 1 connector and the AT connector to connect an external antenna tuner. If you connect the external tuner to the ANT 2 connector, the external tuner will not function. Note: While using an external antenna tuner with the TS-570S, you cannot use the 6 m band to transmit. Connect your 6 m band antenna to the ANT 2 connector. External antenna tuner TS-570 61
