RS485 systems often have local echo enabled. This means any data transmitted by a device is echoed
back to itself.
The USB-RS485-PCB allows for local echo to be enabled/disabled by changing a bit in the FT232R
EEPROM. If CBUS4 in the EEPROM is set for “PWRON#” local echo is enabled. If CBUS4 in the EEPROM is
set for “TXDEN” local echo is disabled.
Users can set this with MPROG from
The default for the local echo is disabled (CBUS4 set for “TXDEN).
