The Ethernet LAN ports are autosensing 10/100 full duplex interfaces.
The two asynchronous serial ports can be used as general purpose ports for
terminals, printers or modems. They are effectively identical and can be
independently configured. The default communications settings are:
•
9600 bps
•
8 data bits
•
1 stop bit
•
no parity
•
hardware flow control.
Power Supply
The AT-AR745 is available in two power supply configurations: a universal AC
model and a 48V DC model. The AC model includes an inlet for the AT-RPS
745 (Redundant Power Supply). The AT-RPS 745 can be purchased separately,
and each unit supports up to two AT-AR745 routers.The AT-RPS 745 is
compatible with the AR725, AR740, and AR745 routers.
