APAX-5580 Interface (COM1)
APAX-5580 offers one standard RS-232/422/485 serial communication interface
ports: COM1. The setting can be adjusted in the BIOS page, the driver will be
installed automatically during OS installation
2.2.1
RS-232 Interface (COM 1)
The APAX-5580 offers one RS-232 serial communication interface port: COM1.
Please refer to Appendix A.3 for its pin assignments.
2.2.2
Automatic Data Flow Control Function for RS-485
In RS-485 mode, the APAX-5580 automatically detects the direction of incoming data
and switches its transmission direction accordingly. So no handshaking signal (e.g.
RTS signal) is necessary. This lets you conveniently build an RS-485 network with
just two wires. More importantly, application software previously written for half
duplex RS-232 environments can be maintained without modification.
2.3
LAN: Ethernet Connector
The APAX-5580 is equipped with two Gigabit LAN controllers. The controller chip
used in both model are Intel 1 x i218 and 1 x i210 Ethernet controller that is fully com-
pliant with IEEE 802.3u 10/100Base-T CSMA/CD standards and IEEE 802.3ab spec-
ification for 1000Mbps Ethernet. The Ethernet port provides a standard RJ-45 jack on
board, and LED indicators on the front side to show its Link (Green LED) and Active
(Yellow LED) status.
2.4
Power Connector
The APAX-5580 comes with a Phoenix connector that carries 24 V
DC
external power
input, and features reversed wiring protection. Therefore, it will not cause any dam-
age to the system by reversed wiring of ground line and power line. Please refer to
Appendix A.4
2.5
USB Connector
The USB interface supports Plug and Play, which enables you to connect or discon-
nect a device whenever you want, without turning off the computer. The APAX-5580
provides four connectors of USB interfaces, which gives complete Plug & Play and
hot swapping for up to 127 external devices. Two of the four connectors are USB 3.0
standard. The USB interface complies with USB EHCI, Rev. 2.0 compliant. The USB
interface can be disabled in the system BIOS setup. Please refer to Appendix A.6 for
its pin assignments.
Note!
APAX-5580 with i218 LAN chip can support AMT7.0.
