Dual RS-232 Ports
Dual RS-232 ports are supported on the RDB.
Figure 16
illustrates the serial port connection using a
MAX3232 3.3 V RS-232 driver to interface with a 9-pin D type female connector. This serial connection
runs at up to 115.2 Kbps.

PCI Bus
The 32-bit PCI interface connects to a 32-bit 3.3 V PCI slot and a miniPCI slot (see
Figure 17
).
