AT-AR022 ETH PIC

The AT-AR022 ETH PIC provides a dual Ethernet 10BASE-T/AUI port. Only
one interface type can be active at any one time and the PIC automatically
senses which interface is in use. The 10BASE-T interface uses an RJ-45
connector and the AUI interface uses a DB15 connector.
AT-AR022 ETH PICs are not recommended for use in AT-AR040 NSM PIC
bays because performance of these interfaces is likely to be reduced and packet
loss may occur.
The AT-AR022 ETH PIC is shown in
listed in Table 6.

LED Function
Link Lit when the Ethernet interface is connected to a device (e.g. a hub) which is
generating link pulses.
Data Lit when data is being transmitted or received over the Ethernet interface.
The AT-AR022 PIC is a single card.
