LED Meaning

cpu

This green LED should flash once per second. If it flashes at another rate, there is

a problem with the RS232, RF, or Link outputs. If it glows steadily, this may

mean that the RANCPU has not yet been downloaded with a program. This is

OK: the lED should start flashing normally after the control program has been

downloaded—unless there is a Link problem.

Indicates that data is being received on the RF input. This LED should be off

unless the RANBROAD has the optional RF section. If this LED is constantly on,

contact Rauland Borg.

Slave

Indicates that data is being received on the RS232 Out connector.. If this LED is

constantly on remove the RS232 Out connector and the RS232 In connector to

see when it goes off.

Links 1–10

Indicates that data is being received on the RS232 Out connector.. If this LED is

constantly on, remove the appropriate field wiring

Power Indicates that the unit is powered up.
