 ======Serial Port Programming======
-WattmonPRO comes with an RS-232 serial interface on pins 7 and 8 and an RS-485 port on an RJ45 connector.  The device is configured by default for RS-232 voltage levels and by using a simple DB9 cable can be connected to any serial device.  For specific devices that require TTL levels, a jumper setting inside the device can bypass the level converter IC and it can thus be used to interface with sensors or other devices at 3.3V DC.
