The NTC-3000 is a DCE (Data Circuit-Terminating Environment), so the RTS (Ready To Send) signal is received by the NTC-3000 and the CTS (Clear to Send) signal is transmitted
with flow controlled from both ends.
The DCD (Data Carrier Detect) line is permanently set to one state, i.e. in the high state at the connector, GND at the chip.

A suitable power supply is available on request or via direct purchase from the NetComm Online shop. It is recommended that the NTC-3000 be powered using a 12VDC/1.5A power
supply.
