converter  will  start  to  transfer  the  UART  message  to  the 
CAN Bus.

 

 

 

 

Pair  Connection Command  Timeout: 

Only the tM-7530 and 

I-7530A-MR  supports  this  function.  The  CAN  timeout  is  used 
to  decide  the  transformation  timing  of  the  CAN  messages  to 
the  UART  messages.  After  the  CAN  converter  receives  the 
CAN message, it will not transfer the CAN  message to UART 
message  until  the  time  of  the  CAN  timeout  passes.  If  users 
would  like  to  transfer  the  CAN  message  to  UART  messages 
immediately,  set  this  value  to  0.  The  function  of  the  UART 
timeout  is  similar  with  the  CAN  timeout.  It  is  decide  the 
transformation  timing  of  the  UART  messages  to  CAN 
messages. Only the configuration of the end characters of the 
UART  message  is  none,  the  UART  timeout  is  useful.  After 
receiving  one  character  from  the  UART  interface,  the  CAN 
converter will not transfer the data until the time of the UART 
timeout passes.

After  finishing  the  configuration,  users  can  click  the  button 

“Save 

All  Setting

”  to  save  the  configuration  in  to  the  EEPROM  of  the 

CAN  converter.  If  users  would  like  to  recover  the  parameters  to 
the  factory  default,  click 

“Load  Default  Setting”  button  to  recover 

all of the configuration parameters to be default value. Afterwards,
