E-EQ-MX2RG-L-ARC MX2 Reference Guide
Using PC Cards
Note: The PC card slot of the MX2 is not user accessible, but functions in the same manner as
the LXE 2325 for software installation, use and general features. Please refer to the
"LXE 2325 Reference Guide” for PC card information.
The MX2 has a slot for plugging in PC cards, and each unit is factory-equipped with Phoenix
CARD Manager Plus PC card drivers. PC cards provide such features as network connectivity,
modem connectivity, and wireless capability. Their primary purpose in the MX2 is to provide
additional memory storage by functioning as a disk drive.
The MX2 holds one PC card at a time. If the MX2 has a radio card installed, the radio card will
need to be removed before a different PC card can be inserted.
The IR Serial Port
Figure 2-4 The IR Port on Bottom of Unit
The serial port is a half duplex IR (Infrared) port. Through software commands, the port may be
set up for IR or a modified RS-232 serial communication.
In general, the IR mode is used when communicating to other IR devices (printers, computers,
etc.) and the modified RS-232 mode is used to communicate with the dock for host
communications.
In IR mode, all physical communications meet the IrDA physical layer specification. In the
modified RS-232 serial mode, the IR port is used to transmit RS-232 level data out the IR port.
With the MX2 in the dock, the keypad facing the front of dock, the left-most pad is the RS-232
input (RXD) into the MX2 while it is in the dock.
Note: The MX2 does not propagate the RS-232 hardware signals such as RTS, CTS, DTR,
DSR, RI and DCD.
When transferring files using the IR port, flow control must be the same on both sides of the
transmission (specifically, with Zmodem: both sender and receiver must use Xon/Xoff).
