INSTALLATION
BASE STATION INSTALLATION
The FT-8800Ris ideal for base station use as well as in mobile installations. The FT- 8800R is specifically designed to integrate into your station easily, using the information to follow as a reference.
AC Power Supplies
Operation of the FT-8800Rfrom an AC line requires a power source capable of providing at least 15 Amps continuously at 13.8 Volts DC. The FP-1023and FP-1030AAC Power Supplies are available from your Yaesu dealer to satisfy these requirements. Other well- regulated power supplies may be used, as well, if they meet the above voltage and current specifications.
Use the DC power cable supplied with your transceiver for making power connections to the power supply. Connect the RED power cable lead to the POSITIVE (+) power supply terminal, and connect the BLACK power cable lead to the NEGATIVE (–) power supply terminal.
Packet Radio Terminal Node Controller (TNC)
The FT-8800Rprovides a convenient rear-panel DATA jack for easy connections to your TNC. This connector is a standard mini-DIN connector. A pre-wired connector and cable assembly option, model CT-39A, is available from your local Yaesu dealer.
The FT-8800R’s DATA jack connections are optimized for the data transmission and reception speed in use. In accordance with industry standards, the signal levels, impedances, and bandwidths are significantly different on 9600 bps as opposed to 1200 bps. If your TNC does not provide multiple lines to accommodate such optimization, you may still be able to utilize your TNC, if it is designed for multiple-radio use, by connecting the TNC “Radio 1” port to the 1200 bps lines on the FT-8800R, and the “Radio 2” port to the 9600 bps lines.
The pin connections of the Data connector are shown below.
