Note: This unit is Data Communications Equipment (DCE). In accord with the RS‐232
specifications, the data output pin of this port is therefore labeled RX even though
asynchronous data is leaving the device through this connection. The RX pin on this
unit should be connected to the RX pin on Data Terminal Equipment (DTE) such as
a PC COM port. Similarly the input pin on this device is labeled TX, and should be
connected to the TX pin on a PC or other DTE device.
