RouterBOARD 333 serial console application note
This applies to RouterBOARD 333 only.
Some valid Serial Null modem cables may not work with RB333, many others following the
standards will work fine. In case your cable does not work, the serial connector pins number 1 and 6
should be removed with pliers to enable various standards compliant cables to work. Hardware
Flow control should be disabled when connecting to the device.
Alternatively you can open up your serial cable and disconnect the wires that go to the pins 1 and 6.
All serial cables that have been shipped with MikroTik products will work without any
modifications to the board or cable.
