TLU Toggling Locked
Functions
Send the toggle lock/unlock (TLU) command to set locked functions to an
unlocked state or unlocked functions to a locked state. The module
processes the command, then returns a character string that indicates
whether or not interface functions are unlocked.
TLU command from host: TLU
↵
Example response from module: 1 UL ON
↵
• The “1 UL ON” response means interface functions are locked.
• The “0 UL OFF” response means interface functions are unlocked.
You must send the UNL or TLU command before you send any of the
commands listed in Table 5-3.
SB Set Baud Rate
The example set baud rate (SB) command sequence sets the baud rate to
2400 baud:
Example SB command from host: SB2400
↵
Response from module: PROGM OK
↵
Valid values are 1200, 2400, 4800, 9600 (default), or 19200 baud.
The module communicates in half-duplex mode. Neither the module nor
the host computer can send and receive signals at the same time. The host
issues a command, then waits for a response from the module.
The time between reception and transmission of data does not depend on
the baud rate. The host must shut off within the time T, then must wait for
the module to process the command (time H) and return a response
(time D), as illustrated in Figure 5-1.
• Table 5-4 lists limits on timing and response delays.
• Table 5-5 lists the time required for the module to respond to each
command type.
