<P1
CR/LF : data being transmitted
<N1
CR/LF : transmission failed, no response from destination station
Notes
Set the message length to 255 byte or less. The message length exceeding 255
byte will be command error.
Message must be terminated with 2 byte (CR/LF) character, others will be
command error.
In broadcast transmission, the receiving result of the destination station cannot
be confirmed at the sender side.
TBR Transmit Binary Data through Repeater
Syntax
TBR [repeater address] [destination address] [message byte length]{Local Station
Address}[message]
Repeater address : repeater address to pass through (000 to 999)
Destination address : address of destination station (000 to A23)
Message byte length : message byte length (001 to 255)
Local Station Address : local station address for 485 mode (000 to A22).
Message byte : arbitrary binary data (255 or less)
Response
P0 : data transmission succeeded
P1 : command accepted, data being transmitted
P2 : data packet reached to repeater
N0 : command error (Except 485 mode)
N1 : data transmission failed -- no response from destination station
N2 : data transmission failed -- destination station is in the reception disabled state
N3 : data transmission failed -- destination station cannot receive because its receive
buffer is full
Function
In the packet transmission mode, transmits binary data through repeater.
Any message length between 1 to 255 bytes is accepted.
The modem counts the number of message characters and transmits the message.
For broadcasting messages to multiple modems, set the destination address to
255. In this case, the modem retransmits the message the number of times of the
Retransmission count plus 1, and then it will return “P0”.
In case the global addressing command is issued to plural modems connected by
RS485 multi-dropping interface, the transmission stops when any modem outputs
“P0”, “N2” or “N3” response to the RS485 line.
Example
>TBR100002005HELLO CR/LF : transmit “HELLO” from station 001 to station 002
<P1
CR/LF : data being transmitted
<P2
CR/LF : data packet reached to repeater
<P0
CR/LF : data transmission succeeded
Notes
Set the message length to 255 byte or less. The message length exceeding 255
byte will be command error.
Message must be terminated with 2 byte (CR/LF) character, others will be
command error.
In broadcast transmission, the receiving result of the destination station cannot
