Description
The RS485 + IoT card is the standard EIA485 serial interface. The RS485 + card does not require
an additional flow control line, because the direction of flowing data switches automatically.
Thanks to a special connector, the device has the possibility to extend its functionality with addON
expansion cards.
The IoT card is compatible with mangOH Green, Red, Yellow and FX30 / FX30S.
Mounting the card in the host
It is recommended to install the IoT card when the power is off to avoid accidental short circuits. If
the card is installed with the power on, it is necessary to reboot the program.
c
Depending on the device used, the card is mounted using standoffs/spacers (mangOH) or rails
(FX30). The IoT card also have dedicated cover for locking inside FX30.
Important!
Never mount or remove the addON card with power on!
