BT (Guard Time Before) Parameter
<Non-AT Settable Parameter: AT Command Options> BT Parameter is used to set the DI pin silent
time that precedes the command sequence character (CC Parameter). By default, 1 half of a sec-
ond (500 milliseconds) must elapse before entering another character. The AT Command Mode
Sequence used to enter AT Command Mode is as follows:
"No characters sent for 1 millisecond [BT (Guard Time Before) Parameter]
"Send three plus characters "+++" [CC (Command Sequence Character) Parameter]
"No characters sent for 1 millisecond [AT (Guard Time After) Parameter]
All of the values in this sequence can be adjusted. AT Command is used to adjust the period of
silence that precedes the command sequence character.
Parameter Range: 0 - 0xFFFF (x 1 millisecond)
# of bytes returned: 2
Default Parameter Value: 0x1F4 (500 decimal)
Related Commands: AT (Guard Time After), CC (Commands Sequence Character)
CC (Command Sequence Character) Parameter
<Non-AT Settable Parameter: AT Command Options> CC Parameter is used to adjust the com-
mand sequence character used when entering AT Command Mode.
The AT Command Mode Sequence used to enter AT Command Mode is as follows:
"No characters sent for 1 millisecond [BT (Guard Time Before) Parameter]
"Send three plus characters "+++" [CC (Command Sequence Character) Parameter]
"No characters sent for 1 millisecond [AT (Guard Time After) Parameter]
Parameter Range: 0x20 - 0x7F
# of bytes returned: 1
Default Parameter Value: 0x2B (ASCII "+" sign)
Related Parameters: AT (Guard Time After), BT (Guard Time Before)
CD (DO3 Configuration) Command
<AT Command: Serial Interfacing> Used to rede-
fine the RX LED I/O line.
AT Command: ATCD
