CONNECTORS
The connectors on the IOT1601JM board are self-explanatory. However, if communication will be
made through a NemLink card, then the connector J7 should be used with the comms cable
supplied with the unit (jumper selection TTL Serial). Also note that the FG7-Druid does not
support RS485 multidrop, only daisy chain – so there is a RS485 OUT and a RS485 IN terminal.
The TAUT Wire terminal is not used in the FG7-Druid controller.
PUSH BUTTONS
There are two push buttons on the green board. The one is marked “B3 PWR” (Power) and the
other “B3 RESET”. The B3 PWR button is used to manually power the control unit on and off, this
is usually required when programming the settings on the FG7-Druid. The B3 RESET button is
used to manually reset the FG7-Druid Controller.
