5.1.10 Troubleshooting the Front Panel Serial Port

The front panel serial port can be used for SecureSync configuration or to obtain select data.
The serial port is a standard DB9 female port. Communication with this port is via a standard
DB9 F to DB9M serial cable (minimum pinout is pin 2 to 2, pin 3 to 3 and pin 5 to 5) con
nected to a PC running a terminal emulator program such as Tera Term or Microsoft Hyper
Terminal. The port settings of the terminal emulator should be configured as 9600, N, 8, 1
(flow control setting does not matter).
If the terminal emulator program does not display any data when the keyboard <Enter> key is
pressed, either SecureSync is not powered up or there is a problem with the connection
between SecureSync and the PC.
Using a multimeter, ring out the pins from one end of the serial cable to the other. Verify the
cable is pinned as a straight-thru serial cable (pin 2 to 2, pin 3 to 3 and pin 5 to 5) and not as
a null-modem or other pin-out configuration.
Disconnect the serial cable from SecureSync. Then, jumper (using a wire, paperclip or car key,
etc.) pins 2 and 3 of the serial cable together while pressing any character on the PC's key
board. The character typed should be displayed on the monitor. If the typed character is not
displayed, there is a problem with either the serial cable or with the serial COM port of the
PC.
