3.1.4 COM1~COM4 serial ports

The PCM-7230 offers four full-functions RS-232 (COM1, COM2, and COM3) and one RS-485 w/ AFC (COM5) serial communication interface ports.

¾Automatic Data Flow Control Function for RS-485

The RS-485 in PCM-7230 will automatically sense the direction of incoming data and switch its transmission direction accordingly. Therefore no handshaking signal (e.g. RTS signal) is necessary. This feature lets users build an RS-485 network simply and quickly with just two wires. More importantly, application software previously written for half duplex RS-232 environments can be maintained without need for modification.

3.1.5 LAN: Ethernet Connector(CN9,Pin1~Pin6)

The PCM-7230 is equipped with one Davicom DM9000 10/100 Base-T Ethernet LAN controller. The second and third LED indicators (approach AMI-120 Interface) on board show the Link and Active (Green LED) status of this Ethernet port.

3.1.6 USB client connector(CN9,Pin47~Pin50)

This USB client connector is used to communicate with PC for ActiveSync. Users may connect the PCM-7230 with PC to develop their own applications and download files to PCM-7230.

3.1.7 DC power connector(CN29)

The DC power connector carries 12 VDC external power input and features reversed wiring protection. Therefore, it will not cause any damage to the system by reversed wiring of ground line and power line.

3.1.8 LCD display connector(TTL level:CN18 ; LVDS:J1)

This 40-pin LCD display connector is for LCD connectivity.
