AT-AR024 ASYN4 PIC

The AT-AR024 ASYN4 PIC provides four additional asynchronous RS-232
ports with RJ-45 connectors for use up to 115 Kbps.
There are no user-configurable jumpers or dip switches on the AT-AR024
ASYN4 PIC board.
The AT-AR024 ASYN4 PIC is shown in

AT-AR026 4ETH PIC

The AT-AR026 4ETH PIC provides four 10BASE-T/100 BASE-TX auto-
negotiating ports. The ports support wire speed unmanaged layer 2 switching
and have RJ-45 connectors.
The AT-AR026 4ETH PIC is shown in
are listed in Table 8 on page
AT-AR026 4ETH 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.
