2 RD (Received Data): Received data from the PC. Input signal to the DX.
3 SD (Send Data): Transmitted data to the PC. Output signal from the DX.
5 SG (Signal Ground): Signal ground.
7 RS (Request to Send): Handshaking signal when receiving data from the PC. Output signal
from the DX.
8 CS (Clear to Send): Handshaking signal when transmitting data to the PC. Input signal to
the DX.
* Pins 1, 4, 6, and 9 are not used.

RxD/TxD-P: Positive data input/output.
CNTR-P: RTS (needed when using a repeater).
DGND: Ground.
VP +5V: +5 V.
RxD/TxD-N: Negative data input/output.
* Pins 1, 2, 7, and 9 are not used.
** The DX does not have a built-in terminator. If you need to terminate the cable at the
DX, use a terminated connector.
