Front Panel RS-232 / Ethernet (DB9) / RJ45 Interface
The Front Panel CST 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 by the SMC, no other handshake signals are provided. Refer to the
SMC section of the MPC8250 User’s Manual for features and programming information. 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.
