MODBUS protocols are only available on RS-485 and USB communication.
Default protocol is TITAN-ASCII (no CRC).
TITAN-SVX Windows UI only supports Communication Mode 0 and 1. If the
TITAN-SVX unit is configured with any other protocol, use the TITAN Windows
UI program or the Special Request Commands to change the protocol back to
Communication Mode 0 or 1.
2.4. Special Commands
TITAN-SVX has Special Request commands that are recognized by all protocols
available on the TITAN-SVX.
Special commands are useful in determining the protocol and network ID of the
TITAN-SVX regardless of which protocol the TITAN-SVX is configured with.
Special Request commands can also be used to change the protocol from one to
another. For example, changing from MODBUS-RTU to TITAN-ASCII can be
easily done using the Special commands.
NOTE:
Special Request Commands must be used with only single TITAN-SVX at a time.
Multiple TITAN-SVX must NOT be on the RS-485, USB, or Ethernet network.
