NORMAL RS232 CABLE

A front and a rear RS232 connection is provided. You choose which one to use by setting the front panel switch. Only one can be active at any time, indicated by a green LED. The RS232 port is selected as one of the communication options in the iDR System Manager Preferences item.

The front panel connection is for updating the iDR unit operating code via your PC COM port. You can also use it to run iDR System Manager with the unit by setting up a PPP dial- up connection. However, this is much slower than the recommended TCP/IP connection.

The rear panel RS232 port is for connection to a modem. This lets you communicate with the iDR-8remotely over a standard telephone line. You can also use it for direct connection to a PC running iDR System Manager but, once again, this is much slower than using the network port.

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.

Internet Protocol TCP/IP

Same Username as iDR-8

Same Password as iDR-8

Selecting RS232 Communication Option

First check that the RS232 port is active. Deselect the front panel switch so that the rear RS232 port is selected. Now check that the ‘active’ indicator next to the rear RS232 connector is 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 serial ports A and B. To use RS232 make sure one of the top three is selected. Reboot the iDR-8 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-8 PPP settings Go to menu *6 PPP

Settings. Under menu *6.1 set the host IP address. The iDR-8is the host. Under menu *6.2 set the client IP address. The PC is the client. The iDR-8allocates 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-8. 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.
