Dutec I/O Plexer Repeater, Manual

Page: 32 / 35

Setup 3
3 - 3
Baud Rates:
Any one of the standard baud rates of 300, 600, 1200, 2400, 4800, 9600, 19200, or 38,400 can
be used for the serial network communications. The sequential display indicates the letter H
followed by a baud rate divided by 100. As shipped the I/O Plexer Repeater are set up for
9600 baud, the display will indicate H 096.
Network type switch:
The I/O Plexer Repeater network switch must be set to the last unit position (as in figure 3-1).
The digit after the L in the sequential display represents how the network switch under the
cover plate is set. This should always be set to “last unit” therefore the sequential display
should always be L 3.
Note : The seven segment display will not reflect a switch position change until power to the
unit has been cycled.
Modem Jumpers:
If modems are not being used, the jumpers should remain in place, as shipped, in a horizontal
position (see page 2-6)
Changing setup parameters
During setup, the user may need to change the unit number, serial link baud rate, and the
input/ output separator positions on
UNIT O . The pushbutton located under the removable
cover is used to change these parameters. The pushbutton causes the adjacent 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 push button LED once when the = appears, places the unit in
setup mode. The value of each setup<< Index will generate here >> 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 Repeater
then stores all values in EEPROM for automatic use following a power cycle. If desired
changes were not implemented correctly, line power can be recycled and setup via pushbutton
can be repeated as required.
