Note, output modules for LED navigation lights: Alarm threshold level: 34mA. Connected
LED navigation lights shall be self-monitored and have built in life time control. In normal
operation current consumption shall be >38mA. In “alarm” state, current consumption
shall be <31mA.
Common hardware
CPU
All modules use a dedicated microcontroller with onboard memory.
Power supply
The power feed is supervised by the Master CPU and signaled to the connected nodes
via the RS-485 network. Up to 4 power feeds are possible, which are connected in
parallel via a set of diodes. The combination output forms a common power supply for
the connected nodes.
Address of modules
The address of the modules are preset at delivery. Two dials labeled ADR LSB and
ADR MSB are used to set the address. Range is from 0 through 7 only on each dial,
and the setting is in octal values. Never change the addresses, and if replacing a
module, please ensure that the address of the new module is identical to the replaced
module.
