The IDW-90 to be configured is referred here as “remote IDW-90”.
The modem used to configure is referred as “local modem”.
Make sure that the remote IDW-90 is connected to the ISDN line and powered up.
• Connect the local modem to its media (ISDN, PSTN or GSM)
• Connect the PC's COM port to the DTE interface of the local modem.
• Connect the power supply to the mains socket.
• Start a terminal emulation program (i.e. Windows-Terminal)
• Configure the local modem protocol
• 1. If local connection is ISDN, configure with the B channel protocol X.75
and blocksize 2048.
• 2. If local connection uses some analogue modem no special configuration
needs to be done at remote IDW-90.
• Set up an ISDN connection to the remote IDW-90 to be configured by using the
normal dial command: ATD<ISDN-No><CR>. When connected send the remote
escape sequence <++++>. The called IDW-90 configurator acknowledges by
requesting the remote password. enter the correct password (default: no
password, just return). Now work with the configurator by using the
IDW-90+Configurator commands.
• Configure the parameter for the remote IDW-90 from your terminal program
and store them.
• Example:
To change the used B channel protocol to X.75 enter the following commands:
prot 10 <CR> (set protocol to X.75 – blocksize 2048)
save <CR> (save the new configuration)
Hint: The active set of parameters can be displayed on screen by the configurator
with the command “show <CR>”.
If necessary the remote IDW-90 can be reset using the command
“reset
<CR>”.
• Hang up the ISDN connection by leaving the configurator using the command
quit. Leave your terminal program. After the next reset the changes will be active.
Now the configured remote IDW-90 with the new set of parameters can be used.
