Omega A2400 manual Short Prompt SP

Command Set 4-16

Short Prompt (SP)

The Short Prompt command allows the user to specify a desired short prompt ASCII character. A two character hexadecimal value is used to define the desired ASCII character prompt.

Note: Short Prompt command may be sent to the module in either normal addressing or Extended Addressing mode.

The user-defined short form prompt is only recognized by the module when the module is in the Extended Addressing mode. See chapter 7 for details on the Extended Addressing mode.

Avoid using the following hex codes $00, $0D, $23, $24 that are ASCII characters NULL, CR, #, $. Using these codes for prompts will cause an error when opening a channel in Extended Addressing mode.

Write Enable (WE)

The Write Enable (WE) command must precede commands that are write- protected. This is to guard against accidentally over writing valuable data in the module’s EEPROM. To change any write-protected parameter, the WE command must precede the write-protected command. The response to the WE command is an asterisk indicating that the module is ready to accept a write-protected command. After the write-protected command is success- fully completed, the module becomes automatically write disabled. Each write-protected command must be preceded individually with a WE com- mand. For example:

Command: $1WE

Response: *

Command: #1WE

Response: *1WEF7

Command: {01WE
