NOTE: By setting SW5 ON to enable download, the default
parameters will first be restored and saved to the non-volatile
memory, erasing the previously stored communication and
operating parameters. These parameters will take effect after
a hard reset or a power-on reset. A hard reset is invoked by
depressing the hard reset switch, holding for one second,
and releasing. The hard reset switch is shown in Figure 4.1.
The baud rate, as determined by SW1 and SW2, only applies to the
COM1 serial interface. When the optional ethernet interface is
selected by setting switch 4 to the "on" position, the baud rate is set
automatically for Ethernet communication, and switches 1 and 2 are
ignored.
The communication parameters for COM2 can only be changed by
menu configuration. Because COM2 is an auxiliary interface, the
default parameters for COM2 are sufficient for the infrequent use of
this interface, and should not be changed. For example, if a user
changes to a faster baud rate on COM2, a problem can occur when
trying to re-establish communication at a later date. Because there is
no obvious indication that the baud rate has been changed, the next
operator would likely try to reconnect at the default, 9600 baud, and
