E-EQ-MX1RG-D MX1 Reference Guide
COM Ports
Both the COM1 port (endcap) and COM2 port (IR) support 115K baud communications. Power to
the COM ports may be turned off using a terminal emulation configuration utility.
The COM1 port uses Data Carrier Detect and Ring Indicator as computer wake-up events only.
The COM2 port supports two signals, Receive Data and Transmit Data. Therefore, COM2 only
supports half-duplex communications.
PCMCIA Slot
The MX1 features an internal PCMCIA slot that conforms electrically to PCMCIA 2.1
specifications. The slot is located at the top of the MX1 nearest the display.
The slot accepts cards of Types I, II and III. The PC card slot, and the PC card in it, are managed
by Phoenix PicoCard software products which refers to the PC slot as slot 0. The software
(resident in the MX1) can be used to format PC cards.
When formatting PC cards, Phoenix PicoCard identifies the PC cards by slot number and DOS
drive letters. For example, an ATA PC card formatted in slot 0 is given disk drive letter D. If the
MX1 is booted from the ATA PC Card in slot 0, the drive automatically becomes Drive C. The
on-board flash drive changes to drive D until the MX1 is rebooted without an ATA card in Slot 0.
If the MX1 is booted from an SRAM card in Slot 0, the drive automatically becomes Drive A. The
on-board flash drive remains as Drive C.
