RS232 RADIO MODEM
232C-868FR1
The I/O Copy mode stops as soon as the modem returns to Hayes mode (+++ command).
2.2 Quick Setup Guide
The 232C-868FR1 is supplied with all its settings in the default values. It can be used with bundled MTC
workbench software to establish a simple transparent point to point link by following the steps outlined
below.
1. Install the MTC workbench software, supplied on the bundled CD onto your PC.
2. Connect your modem to the COM port of your PC using the supplied RS232 cable, apply
power to the modem and load the MTC workbench software. The PWR and RTS LEDs will
now be on.
3. When prompted to launch auto-configuration select
‘Yes’. The modem will now be automatically detected
by the software program.
4. In the Settings menu change the user level to
advanced. Now repeat auto-configuration by selecting
the option from the Modem menu.
5. From the Tools menu select Terminal and open a
terminal window on the COM port connected to the
modem. You can now type text into the terminal
window, if the Port is opened (By pressing the ‘Open
Port’ button) then the text data will be sent over the
serial link to the modem, as shown opposite.
6. Repeat steps 1-5 using either another PC or a
different COM port on the same PC.
7. If the configuration settings are the same for both
modems then you should now be able to wirelessly
send text from one COM port to the other.
Notes
For full instructions on the use of the MTC workbench software please refer the manual provided
on the CD bundled with the modems.
The modems configuration settings can be changed by double clicking on the modem name,
‘B868-tiny’ under the COM port in the tree window. Once you have changed the settings to those
which you require they can be propagated through to the modems registers by clicking on the
Apply button.
You can also change the configuration settings by entering AT commands into the terminal
window in MTC workbench. Please refer to section 2.3 below for a description of the AT
commands available.
