Defaulting the DXC901 Configuration Memory
The first time a DXC901 is powered on it requires defaulting to remove existing test program
configurations from memory. To default a DXC901 use the following procedure:
1. Set all positions of DIP SW2 to on.
2. Push reset on DXC901. When the MASTER LED flashes, the memory is blank.
3. Reposition the DIP switches for the correct node and network address, and press
the DXC901 reset button.
The DXC901 is now ready for the desired site configuration. (See N ETWORK C ONFIGURATION
of Chapter C - DNA100.)
Failure to default the DXC901 may result in undesirable operation at start up or in the future.
INDICATOR DESCRIPTION L.E.D.’s : Figure 11.
DTMF - Flashes when the DXC901 is sending tones during dialing.
TONE ACK - Flashes when a valid digit has been dialed by the DXC901.
CHARGE - Lights steady if power supply is charging batteries. Will be off if charge voltage
drops.
BLANK - For future use.
RECEIVE - Receive data from the Network. Will flash when data is transmitted from another
device on the network. If the Master LED is on, the RX LED will flash when other
devices respond to scanning from the Master. When the Master LED is off, the RX
LED should flash constantly.
TRANSMIT - Transmit data to the Network. Will flash when the DXC901 sends data out on the
Network. If the Master LED is on, the TX LED will flash constantly. When the Master
LED is off, TX will only flash when transmitting to other devices.
MASTER - Illuminates when the DXC901 is a master on the network. There can only be one
master on each network. On power up, each device waits for a response from a
master. If no response is received, then this device will take over as a master.
Therefore, the first device powered up will be the master.
RUN - On steadily approximately 1 second after reset. Indicates DXC901 local
microprocessor is running.
SWITCHES : Figure 11.
SW1 - Reset. Creates a reset for the DXC901, and will send display updates to all nodes.
SW2 - Selects Node and Network address.
