Packet Forwarding Commands

This section allows you to set a variety of packet definition options. The first criteria 

that is met causes the packet to be transmitted. For example, if you set a 

 of 

 ms and a 

 of 

 bytes, whichever criteria is met 

first is what will cause the packet to be transmitted.

This section allows you to control the frame that is transmitted by defining the start and 

end of frame character(s). If the internal buffer (1024 bytes) is full before the EOF 

character(s) are received, the packet will be transmitted and the EOF character(s) search 
will continue. The default frame definition is SOF=00 and EOF=00. 

Enable or disable the end trigger1 hex character.

Enable or disable the end trigger2 hex character.

Enable or disable the eof1 (end of frame) hex character.

Enable or disable the eof2 (end of frame) hex character.

Enable or disable the sof1 (start of frame) hex character.

Enable or disable the sof2 (start of frame) hex character.

When enabled, specifies the character that when received will define when the packet is 

ready for transmission. The transmission of the packet is based on the Trigger 
Forwarding Rule. Valid values are in hex 0-FF. The default is 0.

When enabled, creates a sequence of characters that must be received to specify when 

the packet is ready for transmission (if the End Trigger1 character is not immediately 

followed by the End Trigger2 character, the IOLAN waits for another End Trigger1 
character to start the End Trigger1/End Trigger2 character sequence). The transmission 

of the packet is based on the Trigger Forwarding Rule. Valid values are in hex 0-FF. 

The default is 0.

Specifies the End of Frame character, which defines when the frame is ready to be 
transmitted. The transmission of the frame is based on the Trigger Forwarding Rule. 

Valid values are in hex 0-FF. The default is 0.

When enabled, creates a sequence of characters that must be received to define the end 

of the frame (if the EOF1 character is not immediately followed by the EOF2 character, 
the IOLAN waits for another EOF1 character to start the EOF1/EOF2 character 

sequence), which defines when the frame is ready to be transmitted. The transmission 

of the frame is based on the Trigger Forwarding Rule. Valid values are in hex 0-FF. The 
default is 0.
