Communicating Using an RS232 Dial Up Connection
The rear panel RS232 port is for connection to a modem. This
lets you communicate with the iDR-4 remotely over a standard
telephone line.
You can also use it for direct connection to a PC running iDR
System Manager but this is much slower than using the
network port and is not recommended.
To use the RS232 port you need to access the front panel
menu system to set the PPP settings. You also need to have
RS232 selected as one of the communication options. This is
done using the iDR System Manager software.
Selecting RS232 Communication Option
First check that the RS232 port is active. The green ‘active’
indicator next to the rear RS232 connector should be lit. If it is
not then you need to use the iDR System Manager to make
RS232 active. Note that doing this may disable one of the
other ports being used with the system.
Using iDR System Manager Click on the File menu /
Preferences / Communications Options item. This opens up
the Select Communications Option window. You can select
from the displayed combinations which options are associated
with the two serial ports A and B available. To use RS232
make sure one of the top two is selected. Reboot the iDR-4 for
the changes to take effect.
Setting up a Dial-up Connection
You can simply use the factory default PPP settings. In that
case skip step 1 below. However, you can change these if you
have a reason to do so. Do this using the front panel menus.
1 Changing the iDR-4 PPP settings Go to menu *6 PPP
Settings. Under menu *6.1 set the host IP address. The iDR-4
is the host. Under menu *6.2 set the client IP address. The PC
is the client. The iDR-4 allocates the client address to the PC
during the PPP communication. The host and client addresses
must not be the same. Use menu *6.3 to set the Username,
and menu *6.4 to set the Password. Both can have up to 16
characters and are case sensitive. You need to reboot the unit
for the changes to take effect.
2 Setting up the PC dial-up connection You need
administrative rights to your PC. You must have a MODEM
installed for the COM port you wish to use. Under the Network
and Dial-up Connections menu select the ‘Make New
Connection’ option. Use the same Username and Password as
set up on the iDR-4. Name this connection for future use with
the unit. If you need further information on how to set up the
connection please refer to your Windows™ version Help file.
