Front Panel RS-232 / Ethernet (DB9) / RJ45 Interface
The Front Panel port supports 2-wire RS-232 on a DB9 connector and 10/100BaseT Ethernet on a RJ45
connector. See tables below for connector pinout.
Only the TXD and RXD signals are supported, no other handshake signals are provided. The table below shows
the signals supported along with the Host hardware resource responsible the RS232 signals.
The front panel also supports a 10/100BaseT Ethernet port. The connector is configured and an MDI-X port that
can be connected to a laptop using a standard cable. In essence, the transmit and receive signal pairs are
reversed on the BRC front panel compared to that defined in IEEE Std. 802.3 Clause 14.5.1. The Ethernet PHY is
a Broadcom BCM5221. Its address (4:0) is '00100'. Both the Front Panel Ethernet PHYand the CP2 PHY
(BCM5222) communicate to the Host via the "bit -banged" GPIO MDC and MDIO signals.

Power Amplifier Module Overview
The GTR 8000 Power Amplifier (PA) is a hot-swap capable, forced convection cooled RF power amplifier. It
accepts a low-level modulated RF signal from the transceiver module, and amplifies it for transmission via the site
transmit antenna. Also, to complete the Cartesian correction loop (GTR 8000’s linearization method), it provides a
low level RF feedback signal to the transceiver module to achieve the required transmitter linearity. The power
amplifier consists of the several sub-circuits and boards including core, driver, final, isolator, low pass filter, power
converter and distribution.
