Back-Box
The DAD104 can be mounted into a desk (BBD905), flush (BBF863) or surface (BBS863) back
box. When panel mounting the DAD104 for use in a console or control panel, a back box may not
be necessary but can be used to enclose the DAD104 electronics if protection is required.
REAR LED INDICATORS .
RUN -Indicates the local processor in the DS16 is running. Will illuminate after power up or reset.
MAST - Will light steady if this node is the 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.
TX - Transmit data to the Network. Will flash when the DS16 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.
RX - Receive data from the Network. Will flash when data is transmitted from another device to 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 will flash constantly.
