2.14 Addressing External Data Bus Devices
The table below defines an address map for the external data bus devices which include the
ECC-LOC, ECC-RPU, ECC-RM, ECC-50DA, and ECC-125DA. Dipswitches are used on each of
these devices to set the bus address in order to properly communicate with the ECC-50/100 panel.
Any combination of up to eight (8) remote consoles (ECC-LOC, ECC-RPU, and ECC-RM) can be
