Now configure the Device for a Radio Connection.
Point to Multipoint Connection
In Point-to-Multipoint communication, the master dials a slave or visa versa. Communication is then
established between these two modems and is controlled by Hayes
TM
AT command set. This Mode is used
when the master is required to communicate with more then one slave.
Both modems are configured point-to-multipoint by default.
Dial remote modem (it does not matter which modem dials)
Type ‘ATDT nnnnXX’
nnnn - Receiving Modem’s Address (number)
XX - Extension Address of the port:
00 for Main Port
01 for Auxiliary Port
92 for Remote Menu
99 for Loop Back Port
This will establish a communications link. The front panel LEDs N

will be activated on both modems. Each modem will echo the message
“
CONNECT
” onto the terminal.
The Rx (R
ECEIVE
) and Tx (T
RANSMIT
) data LEDs will flash as information is passed. If both modems
are connected to a terminal, information typed at the computer connected to one modem will be
shown on the screen connected to the other.
Once communication is finished, hang-up the modem with the following sequence:
Type ‘+++’ on the terminal rapidly (within 1 second).
Wait 1 second and the modem should echo “OK”.
Type ‘ATH0’
Both modems should echo “NO CARRIER”.
Point to Point Communication
Point-to-Point Communication is similar to a wire that directly connects two devices together for data
transfer. Radio communication is established automatically and is transparent. This is used when data is to
be sent between two devices only.
Set both modems to Point-to-Point Communication Mode by:
Ensuring the Auxiliary Port of the modem is connected to a Com port and that the
terminal package has the settings as in Setting up for a connection Step 1 on page 8.
Hold Mode Select Button on the front panel of the unit to select Mode 6 – config.
This will bring up the Configuration Menu on the terminal.
Press ‘R’ to select “
Radio Configuration Menu
”.
Press ‘P’ to select Mode Point to Point (Direct).
Enter receiving modem’s address (20 by default).
