Modem Cable
When attaching the DB25 of the SDS1101 to the DB9 com port on a PC, use
a standard straight-through serial cable. The figure below shows the pinouts
for a DB25 to DB9 straight-through cable, often referred to as a "Modem
Cable".
To configure the SDS using the DB9 serial port, you need only pin out the
TXD, RXD, and GND signals.
