Antenna
The MatchPort b/g Pro has been FCC certified with a 5dBi gain antenna for wireless
802.11b/g. It is for applications with antennas of equal gain or less. The following are two
of the recommended antennas with 2.15dBi gain and a link to their vendor. They are
available from Lantronix as well.

Serial Input/Output
The unit has two serial ports compatible with RS232 serial standards at data rates up to
230 Kbps. Serial Port 1 can also be configured as RS422/485, but Serial Port 2 cannot.
The serial I/O signals are 3.3V CMOS logic level. Serial signals can be connected to the
OEM CPU/UART or RS232/422/485 serial transceivers. For evaluation and prototype
work, it is convenient to have an external RS232 interface that can connect to the serial
port on a PC. The MatchPort Demo Board has RS232/422/485 transceivers to implement
this external interface. If desired, use the CPs to create a DTE or DCE-style interface
using any available CPs. To create these interfaces, connect the signals according to the
tables below.
Note: CPx and CPy are any of the available CPs.
