Setup 3
3 - 4
Changing setup parameters via pushbutton:
During setup, the user may need to change the unit address, serial link baud rate,
and protocol pass type. The pushbutton located under the removable cover is
used to change these parameters. The pushbutton causes the adjacent red LED to
flash each time it is pushed. Any changed values are automatically saved in non-
volatile EEPROM.
During the diagnostic test period following the application of power, the
sequential display shows GoGoGo= . Flashing the pushbutton LED once when
the = Appears, places the unit in setup mode. The value of each setup character
can be changed, as they appear in sequence, by pressing the pushbutton. The
display will continue to cycle through the setup sequence until there is a full
cycle with no changes. The I/O PLEXER then stores all values in EEPROM for
automatic use following each power cycle. If desired changes were not
implemented correctly , line power can be recycled and setup via pushbutton
procedure can be repeated as required.
Once the unit has been placed in setup mode, as described above, the value of
each setup character shown below, can be changed.
U0 00 H 096 P 2
-Only the underlined digits may be changed.
The 2 digits after
U0
indicates the master unit control address; initially set for
address
00
H
-00.
Note:
In the address offset mode, only the master unit address is set, The
other addresses are automatically set 40
H
above each other (see page
3-2).
The 3 digits after H show the baud rate (divided by 100); initially set for 1200
baud -
012.
The 1 digit after P signifies the handshake protocol type; initially set for 2 pass
-

The display continues to cycle through its sequence until there is a full cycle with
no changes. The I/O PLEXER then stores all values in EEPROM for automatic
use following the next power cycle.
