• If connecting any other device to this interface, set the baud rate
switches to match the baud rate of the device. See the installation
manual that came with the interface for all baud rate settings.
5. Set the Character Length.
SKIP?
The interface's character length is preset to 8 bits/character.
Unless you are certain that this is inappropriate for your
application, leave the character length setting alone and skip to
step 6.
The character length switches, numbers 0 and 1 on the group labeled U2,
are preset to 8 bits/character, which is appropriate for most applications.
If you know you need to change the character length, refer to the manual
that came with the interface for additional settings.
6. Set the Number of Stop Bits.
SKIP?
The interface is preset to 1 stop bit. Unless you are certain
that 1 stop bit is inappropriate for your application, leave the
stop bit setting alone and skip to step 7.
The stop bits switch, number 2 on the group labeled U2, is preset to 1 stop
bit, which is appropriate for most applications. If you know you need to
change the number of stop bits to 2, change this switch to its alternate
setting.
7. Set the Parity Enable Switch.
