ADAM-5510/P31 2-9
Chapter 2
Watchdog timer setting
Jumper JP2 on the CPU card lets you configure the watchdog timer to
disable mode, reset mode or NMI (Non-maskable interrupt) mode.
Jumper settings are shown below:

Network address/baudrate setting
Set the network address/baudrate using the 8-pin DIP switch located
on the lower right-hand face of the ADAM-5510/P31 front cover. Valid
address settings range from 0 to 63 (00h to 3Fh) where ON in any of
the 6 DIP switch positions bits 1 through 6 equates to a binary 1, and
OFF equates to a binary 0. For example, if the Node ID is 03h, the DIP
switch settings for switches 1 and 2 (representing bits 1 and 2) would
both be ON while the switches 3, 4, 5, and 6 would be OFF. The
default Node ID is 01h.
The two DIP switch positions bit 7 and bit 8 are for baudrate setting,
as shown in the following table:
