from SDU computer
Figure 1-13: Impact of disabling Network A terminal connection on Class B networks during a
download
Figure 1-13 shows how connecting the SDU computer to the
modular phone jack affects downloading data over a Class B
network. Connecting the SDU computer to the modular phone
jack on the CPU module installed in panel B1_CAB3, disables
that CPU module’s Network A port. Downloading data to panels
B1_CAB2 and B1_CAB1 from panel B1_CAB3 is no longer
possible but downloading to B1_CAB4 still is.
Since the microprocessor disables only the Network A port, the
CPU module that doesn’t have a Network A port connection
should be used as the service panel. It is the only panel that is
capable of downloading to every panel on the network using the
modular phone jack.
Note: Connecting the SDU computer to an optional serial
communications port does not affect the Network A port. If a
3-RS232 option card is connected to the CPU, you can download
data to any panel on a Class B network regardless of where the
panel physically connects to the network data riser.
