Setup & Installation 2
2-17(Vol.1)
Setup via Pushbutton:
The pushbutton, located on the logic board (see figure 2-9) is used to configure the unit
address, baudrate, and network pass type.
During the diagnostic test period following the application of power, the sequential
display shows “GO GO GO GO GO
/ “ Pumping the pushbutton once while the /
appears, places the unit in the setup mode.
The BASIC I/O then flashes: U100 H096 P2
The underlined values represent setup parameters that can be changed.
The digit following the U represents whether the unit is analog/digital
where 1 indicates digital and 2 indicates analog. The initial configuration
is default 1 or digital..
The next two digits indicate the unit address; initially set to address 00h
The three digits after H is the baudrate divided by 100; initially set for
9600 baud.
The 1 digit after P is the handshake protocol type; initially set for 2 pass
The value of each setup character can be changed, as they appear in sequence, by pumping
the pushbutton. As the button is pressed, the display will cycle through the possible values for
each character. When the desired character is displayed simply wait for a brief period for the
display to blank. The next character position to be changed will then appear on the display.
The display continues to cycle through until there is a full cycle with no changes. The BASIC
I/O then stores all values in EEPROM for automatic use following subsequent power cycles.
The unit is now in the operational mode and the sequential display becomes:
U1=00 H096 L3 P2
The underlined values represent setup parameters that can be changed
If any desired changes were not completed, line power can be recycled and the setup via
pushbutton can be repeated if necessary.
