Issue
What are the port settings on a DMS panel for UltiVist to communicate serially to it?
Environment
UltiVist
DMS
Cause
DMS panel's serial COM ports settings were reset to factory defaults.
Resolution
The serial COM port on the DMS requires the following settings in order for a serially-connected UltiVist computer to communicate:
PORTx = 9600 1 7 E M N
x = 1* or 2 (* typically PORT1 is used)
1 = stop bits
7 = data bits
E = even parity
M = Multi-drop
N = no modem
