TBN (transmit binary data)
[Format]
TBN (destination-address) (length-of-message-bytes) (message)
- destination-address:
000 to 239
240 to 254 (for group communication)
255 (for broadcast transmission)
- length-of-message-bytes: 000 to 130
- message:
Arbitrary binary data (130 bytes or less)
[Response]
P0: Norm al end
P1: Command is accepted and data are being transmitted
N0: Co mmand error
N1: Data transmission is failed. (The radio modem at the destination address does not respond or
transmission cannot be started because of carrier sensing.)
N3: Data transmission is failed because the receiving data buffer of the destination modem is full.
[Function]
- This command transmits binary data.
- The length of message can be defined from 0 to 130 bytes arbitrary.
- To broadcast data to multiple radio modems, “destination address” should be defined to “255”. At this
setting, the sender FDP02 transmits data packet “re-transmission frequency” that is defined by REG11 + 1
times and then returns P1 and/or P0 response to the host according to the REG13 setting.
[Examples of use]
>@TBN001005HELLO<Cr><Lf>: The FDP02 sends the message “HELLO” to the destination modem
that wireless address is “001” by this command.
<P1<Cr><Lf>:
This response indicates that the command is accepted and the data is
being transmitted.
<P0<Cr><Lf>:
This response indicates the normal end of command processing.
>@TBN002005HELLO<Cr><Lf>: The FDP02 sends the message “HELLO” to the destination modem
that wireless address is “002” by this command.
<P1<Cr><Lf>:
This response indicates that the command is accepted and the data is
being transmitted.
<N1<Cr><Lf>:
This response indicates that transmission is failed because the
destination modem that wireless address is “002” did not respond or
the data transmission was not started by carrier sensing.
The length of message should be not more than 130 bytes. It becomes
command error if the length of message exceeds 130 bytes.
The delimiter of this command should be “<Cr><Lf>”. It becomes command
error if different delimiter is added.
At broadcast transmission mode, the sender FDP02 cannot recognize whether
receiver FDP02s receive the transmitted data or not.
Do NOT execute next command before the sender FDP02 receives P0 response.
If the setting is "Disabling response" and no P0 response is sent to the sender
FDP02, please wait expected P0 response time before executing next command.
If next command is executed before P0 response, command error is occurred and
the system might have unexpected movement.
