Connecting the Serial EtherWind to an RS-232 Serial Device
The EtherWind has one standard PC-compatible 9-pin female D-connectors. The
serial port uses PC-compatible 9-pin male D-connectors. Note that the standard
off-the-shelf 9-pin female to 25-pin male PC cables will require a null modem in
order to connect to most printers or terminals. The pin-outs are as follows:
DB9 DTE DCE
pin Signal Signal pin pin
1 Not used Not used - -
2 Receive Data Transmit Data 2 3
3 Transmit Data Receive Data 3 2
4 DTR out DSR in 6 20
5 Signal Ground Signal Ground 7 7
6 DSR in DTR out 20 6
7 RTS out CTS in 5 4
8 CTS in RTS out 4 5
9 Not used Not used - -
Basically, the cable must connect input signals (e.g., Receive Data) on the TROY
EtherWind to the equivalent output signals (e.g., Transmit Data) on the device
and vice-versa.
The serial port can be set to operate in console mode to allow you to configure
and diagnose the EtherWind via a serial terminal (or PC with a terminal emula-
tion program). To enable the console mode manual, unplug the power supply
from the serial server, hold down the Test switch and simultaneously plug in the
power supply. If no characters are received on the serial port during this time,
then console mode is enabled on the port (if characters are received, then the unit
goes into a special diagnostic mode).
The port will remain in console mode until the unit is power off.
You may also remotely enable console mode by connecting remotely to the
EtherWind via WebXAdmin, TELNET, NCP, or XConfig (refer to Chapter 3 for
information on how to use these utilities). With WebXAdmin, select Configure
