User’s Manual for Advantech SOM-A2558 series module V1.00

2.2.2 COM

SOM-A255x series (SOM-A2552, SOM-A2558, SOM-A255F) all support 5

xRS-232 ports: 3 full function (FF) RS-232 ports, 1x 2-wire (RX, TX) RS-232 and 1x 3-wire (RX, TX, RTS) RS-232 port. COM port function assignments are as following:

ØCOM1: FF RS-232

ØCOM2: FF RS-232

ØCOM3: FF RS-232

ØCOM4: 2-wire (RX, TX) RS-232

ØCOM5: 3-wire (RX, TX, RTS) RS-232

All RS-232 ports are TTL levels.

According to user target CSB demand, user could define COM5 as 3-wire (RX, TX, RTS) RS-232 port or pass through RS-485 transceiver to act as RS-485 function. User could references “Advantech SOM-A255x series CSB design guide “to design the COM5.

2.2.3 USB 1.1 Host

SOM-A255F & SOM-A2558 series supports 2 USB host ports. SOM-A2552 series supports 1 USB host port. The USB host ports on the SOM-A255x are USB 1.1 compatible. The default Windows CE.NET and Linux on board support USB keyboards, mice and mass storage devices. User could check the " SOM-A255x series verified compatible peripherals list " to know the verified compatible peripherals. If user wants to connect other devices, it may take customization on the Windows CE.

2.2.4 USB 1.1 client

The USB client port on the SOM-A255x is USB 1.1 compatible. USB client connector is used to communicate with master device (ex: PC) for ActiveSync. About SOM-A255x series ActiveSync installation, please reference to “Installation Guide-Advantech RISC platform with Microsoft ActiveSync 3.7”.

2.2.5 T/S

SOM-A255x series supports 4-wires (X+, X-, Y+, Y-) resistive T/S interface.

2.2.6 PCMCIA/CF

All SOM-A255x series supports 2 PCMCIA interface (I/F) or 2 CF I/F or 1 PCMCIA & 1 CF I/F. User could check “ SOM-A255x Series Carrier Board Design Guide “ to know how to design the I/F.

PCMCIA/CF I/F power control circuit is designed on SOM module, so PCMCIA/CF I/F is hot-swappable.

Advantech strongly suggest user to design one CF or one PCMCIA slot on user’s target carrier board, even user doesn’t need this port in target product. Advantech platform always use CF or PCMCIA slot to be system S/W upgrading port. If user doesn’t design 1 CF or PCMCIA slot on carrier board, user will run into trouble when user wants to upgrade image, boot loader & boot-logo.
