3.2. Communication Mode 1
Communication Mode 1 is the TITAN-ASCII protocol with No Error Reply. RS-
485, USB, and Ethernet communication are capable if utilizing communication
mode 1.
Communication Mode 1 is exactly same as the Communication Mode 0 except
that only the valid replies are sent back from TITAN-SVX.
Communication Mode 1 can be useful when the RS485 network has other
devices other than TITAN-SVX and in reducing the network traffic.
Example 1:
Command from Master to TITAN-SVX
@01:TEST[CR][LF]
Reply from TITAN-SVX to Master
[No reply will be sent from the TITAN-SVX]
In the above example, an unknown command TEST is sent. TITAN-SVX
does not reply with any error message.
3.3. Communication Mode 2
Communication Mode 2 is the TITAN-ASCII protocol with CRC Checksum with
Error Reply. RS-485, USB, and Ethernet communication will use the format
below.
