The PESA Matrix Frame Controller Debug Port protocol is an RS-232 connection that allows service
personnel to directly interact with the PESA Matrix frame controller in order to determine the health of
the matrix and to perform certain diagnostics. The same protocol is supported via the Telnet
connection; however, the network parameters cannot be configured through the Telnet connection.

D2: Command Syntax
Commands consist of the first two non-whitespace ASCII character sequences entered in a command
line.
Each command is followed by a series of optional data parameters. Data parameters start after the first
whitespace following the command sequence. Commas delimit the data parameters. All data
parameters have leading and trailing whitespaces trimmed.
A command is terminated by a Carriage return. A command is not acted on until the carriage return is
received.
Command sequences are case insensitive.
D3: Command Line Character Input
The following indicates how characters input into the debug port are handled.
1) Command Entry
Commands are entered character by character onto the command line. All ASCII keys are
concatenated onto a string. In addition, entry of the DELETE or BACKSPACE keys will cause
the Last character that was entered to be removed from the character string.
In verbose mode, all ASCII characters entered into the serial port are echoed back. The DELETE
and BACKSPACE keys cause control characters to be echoed that cause the cursor to move back
deleting the last character input.
In terse mode, the input characters are not echoed back.
After a command has been executed, the debug port will output the appropriate response (if any)
followed by a Carriage Return/Linefeed and the ‘>’ character. The receipt of the ‘>’ character
indicates that the next command is ready to be entered.
