SERIAL FEATURES

Serial port usage (RS232)

The serial port on both the Xtensys switch (RJ12) and the User station (DB9) are used to update the unit’s firmware.
The following procedure for establishing a connection from your standalone computer or Notebook computer to the

Xtensys switch’s serial port or a User station uses Windows HyperTerminal™. Refer to your user’s manual if a
different communication program is being used.

To access an Xtensys serial port, the following items are required:



 A serial cable (RJ12 connector and an appropriate adapter for the computer's serial port). The serial cable and



pter are provided with each Xtensys switch (Rose part number KIT-ATRX). A standard DB9 null modem

ada
cable can be used to flash user stations.



 A dedicated computer, Notebook computer with a serial port, or a display terminal. Using a display terminal will



allow you to configure the Xtensys switch; however, you will not be able to upgrade new versions of firmware.
The computer or Notebook must not be attached to any Xtensys switches in the system being upgraded.



 A communications program such as Windows HyperTerminal.

Connecting the Serial Cable

Attach the serial cable from the RS232 port on the Xtensys switch (RJ12 connector) to the COM1 port (DB9M) on
your computer. This COM1 port must be the same communication port your communication software is configured
for. If your communication software is configured for COM2 then connect the cable to this DB9M port.

Setting up Windows HyperTerminal

(The following instructions are using Windows HyperTerminal. The instructions may be different for other operating
systems or communication program)

Start the Windows HyperTerminal program. The “New Connection” dialog box will display requesting a name for this
session. Enter a session name like “Xtensys serial option” and click ‘OK”. Next, the “Connect To” dialog box will
display. Click on the “Connect Using” down arrow to display the connect options. Select the COM 1 option, then
click “OK”. The COM1 properties dialog box will display. Using the drop-down selection boxes, select the following
values for each setting.

Option 1. Receive new main program from serial port (This card only)

When a new main program is available, it can be obtained from Rose Electronics or downloaded from our web site at
www.rose.com. The diagnostic screen that is displayed when the Xtensys switch is first turned on shows the main
program version that is presently installed.
You cannot update the flash memory using only a display terminal; you must use a standalone computer or
Notebook and the new main program saved on that computer.

To load a flash upgrade file, type 1 in the Enter choice field of the serial options menu. The following message will
appear:

updated firmware file into the File Name box and click “Open”. The file transfer function will start. While the file is
being sent, periods are sent to indicate the copying progress. Once the file has been sent, you will see the message:
