Teledyne 2002 instruction manual Command Syntax, Interrogation Commands

RS-485 address (the address is displayed in it’s decimal form). Use the UP or DOWN switch to modify the address. Use the MODE switch to exit this function and save the new address into EEPROM memory.

COMMAND SYNTAX

In the following examples of syntax codes, the special characters are explained:

The characters in square brackets [ ] represents a command string, either upper or lower case command characters accepted. All characters must follow each other in the string with no spaces or other charac- ters.

The characters within wavy brackets { } contain choices for the appropriate command.

The characters within the symbols < > are the common abbreviations for the one digit ASCII control codes which they represent, (e.g. <CR> represents carriage return).

When entering more than one command in the same data string, they must be separated by a comma.

All command strings must be followed by the terminator character (carriage return <CR>, also known as ENTER).

When a lower case character is present in an example it represents an option.
