2 INSTALLATION

Computer Interface (COM)

This connector allows you to directly connect a computer or dumb terminal by using an RS-232C cable terminated with a female 9-pin connector. No external hardware interface is required between your computer and the transceiver if your computer has an unused RS-232C serial communications port. See Appendix D on page 83 for information relating to this connector.

RTTY Equipment (RTTY and ACC 2)

To operate Frequency Shift Keyed RTTY, connect your RTTY equipment as shown below. Connect the RTTY key output from your RTTY equipment to RTTY, and connect the demodulation input of your RTTY equipment to ACC 2, Pin 3. By default, a short condition generates a space; an open generates a mark. However, this can be reversed via Menu settings.

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.

Linear Amplifier (REMOTE)

The REMOTE connector allows connection of an external transmit power amplifier. If using an amplifier, confirm that Menu No. 51 (LINEAR) is set to Ò1Ó (Fast) or Ò2Ó (Slow) {pages 24, 27}. This Menu item controls the linear amplifier TX/RX relay response time. Use the Fast setting unless you experience switching problems when using your amplifier for semi break-in operation.

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.
