CommunicatingwiththeRTU

You can use a Windows Hyperterminal window to connect to the

addSWITCH RTU. After you have installed the system, follow these

steps to configure the device and set the default parameters:

Note: To configure the A724 Series 4 RTU, you must have a special adapter

cable (item number 200.720.540 from your Adcon distributor) and

plug it into the POWER connector.

1. Open a Hyperterminal window.

2. Select the appropriate serial port and click OK.

3. Configure your terminal as follows:

• 19200 baud

•1 stop bit

• 8 data bits

•No parity

• No protocol (neither hardware nor software)

4. Select OK to open the terminal window.

5. Press Enter to generate a response in the window.

Note: Beginning with the A724 Series 4, RTUs operate in two modes,

bootloader and firmware.

BootingtheRTU

Note: This section is included for informational purposes. You will rarely

need to boot the RTU. However, when you do need to do so, you will

work within a Windows Hyperterminal window on your computer.

When the Series 4 RTU starts from a power-up reset (such as when

you connect the battery to the RTU), it enters the bootloader mode. If

you press no keys in the interim, the RTU enters the firmware mode in

five seconds.

If you want to work with commands in the bootloader rather than

continuing to the firmware mode, press ESC within five seconds after

seeing the following sign-on message:

A724_S4 Bootloader V1.7

Press <ESC> within 5 seconds to start the commandline

interface...

You are in the command line interface. The command line interface

enables you to perform certain commands such as rebooting the RTU

and upgrading to a new firmware.

Note: If you press no keys within 60 seconds, the command line interface

will start firmware mode automatically.
