2. Connect the RJ11 connector to a phone line.
3. Connect external power to the power jack via wall adapter or +5VDC.
Hyper Terminal setup:
The modem can be tested as a standard serial data modem by connecting it to a
personal computer or other data terminal equipment (DTE). Any standard terminal program such as
HyperTerminal or ProComm running on a PC will communicate with the modem.
Procedure to setup HyperTerminal:
Check if HyperTerminal is installed in your PC. If not, see HELP on Windows Operating System for
HyperTerminal installation.
1. Start -> Program -> Accessories -> Communications -> HyperTerminal
When the HyperTerminal is opened for the first time, the application will ask for a title for storing all
parameters you want to key in. After a title is given, there will be a prompt for the COM port to be used.
Choose the corresponding port (COM1 is recommended). Then the port setting will be asked. Configure
the terminal emulation program to 19200 bps, 8 data bits, no parity, one stop bit, and hardware (CTS)
handshaking.
2. When the terminal program is properly configured and running, type “AT<cr>” inside the terminal
window and the modem should return “OK”, indicating the modem is working in the command mode and
communicating with the terminal. If the “OK” response is not received, try resetting the modem by
pressing the manual reset switch (S1) then again type “AT<cr>”. If it is still not working, ensure that the
right COM port is selected and make sure the correct port setting is entered.
3. If there is no line-feed after the “OK” response, click File->Properties. In the properties panel, choose
“Settings”. In this panel, choose ASCII setup. In the ASCII panel, click the append line feeds to incoming
lines. Click OK. You are now talking to one modem with the PC.
4. Use a similar procedure to setup the other modem with a different COM port.
5. Once the second modem is set up, the user can choose either one of the modems as the ANSWER
modem.
6. If the modem is chosen as the ANSWER modem, type “ATI6<cr>”. The modem should respond
with “2493”, “2457”, “2434”, “2415”, or “2404”, indicating the terminal is communicating with a
Hidex modem.
7. Type “ATS0=2<cr>”. It means answer the phone after the second ring.
8. To take the modem off-hook, type “ATH1<cr>”. The modem should go to the off-hook state, draw loop
current, and respond with an “OK”.
9. Next type “ATH<cr>” or “ATH0<cr>” and the modem should hang-up (go on-hook) and stop drawing
loop current.
10. To make a modem connection, type “ATDT (called modem phone number)<cr>”. Once the connection is
established, a “CONNECT” message will appear indicating the two modems are in the data mode and
communicating. Typing on one terminal should appear on the other terminal.
