If you enter wrong passwords during three consecutive attempts, the SEL-2020 pulses the
SALARM bit for one second. In SEL-2020 Communication Processors with I/O boards, you can
assign an output contact to SALARM to allow an external system to monitor for invalid access.
In SEL-2020 units without an I/O board, the SALARM bit is automatically routed to the
ALARM contact, causing it to pulse, unless it is already in an alarm condition.
AUTO n (Access Level 1)
The AUTO command displays the results of auto-configuration on a port. The response message
shows the device FID string, the device ID string, the baud rate, the supported operate
commands, and a list of supported “20” commands. The operate command support indicates
whether ASCII or binary operate messages are supported, the number of breakers and remote bits
supported, and the type of remote bit operations supported (set, clear, pulse). Each “20”
command is preceded by an A or B to indicate whether the data will be collected using an ASCII
or binary Fast Meter format. The following screen shows an example of a typical AUTO
command response.

BROADCAST (Access Level 1)
The BROADCAST command allows you to communicate from one master port to all IED ports
simultaneously. When you issue the BROADCAST command, the SEL-2020 will indicate the
connected ports. From then on, anything you enter will be sent to all connected ports.
Any messages from any of the connected IED ports will be sent to the single master port, as long
as they are framed with the <STX>/<ETX> characters. To transfer binary messages, add an
AAh byte after the <STX> character and then a message length as the next byte. The SEL-2020
