SW2 - SW4: Serial Port Baud Rate.
Switches 2 through 4 are used to set the baud rate for the serial port as indicated in the table
below.

SW5: Serial Port Electrical Interface
This switch selects whether the RS-232 electrical interface or RS-422 electrical interface is
used. For typical programming applications you should select RS-232. The
O
PEN
(O
FF
) position
selects RS-232. The C
LOSED
(O
N
) position selects RS-422.
SW6: Program Port Selection
This switch selects whether only TCP port 4452 can be used for programming or whether TCP
ports 1505 and 4450 can also be used for this purpose.
When the switch is in the O
PEN
(O
FF
) position, only TCP Port 4452 can be used to modify the
user program via the local Ethernet port. Requests from TCP ports 1505 or 4450 can display the
user program but attempts to modify the User Program will be rejected.
When the switch is in C
LOSED
(O
N
) position, TCP ports 4452, 1505, or 4450 can be used for all
programming functions, including modifying the User Program.
This switch is provided because some Ethernet programming interfaces, such as APTNet use a
fixed port number of 1505 and cannot use port 4452 for programming.
NOTE:
The switch setting applies to the local Ethernet port only and does not affect programming via Special
Function modules, such as the 2572- A or 2572.
When possible, you should use set the switch to the O
PEN
(O
FF
) position. This setting allows
you to block other users from concurrently modifying the user program by enabling Port Lockout
while you are programming on this port. Port Lockout will prevent users connected to other
physical ports (such as the serial port or a Special Function module) from modifying the User
Program. Other users connected to Port 1505 or 4450 on the local Ethernet port cannot modify
the user program because attempts to modify the user program will be rejected.
