Why does my IMS-4000 Host begin dialing as soon as I turn it on?
l IMS-4000 will only dial to deliver an alarm message. An unacknowledged alarm exists, and IMS-4000 is
trying to deliver an alarm message.
Why can't I connect with my IMS-4000 using my Ethernet network?
l IMS-4000 Hosts and Nodes are 10MB Ethernet devices. If your Ethernet network speed is 100MB, you
won't be able to communicate with an IMS-4000 Host or Node.
l The IMS-4000's Host or Node's network settings may be incorrect. Verify the IP address, Gateway, DNS,
and Subnet mask settings.
l There may be a network IP address conflict. The IMS-4000 Host or Node's IP address may be the same as
another device on your network.
Why can't I connect with my IMS-4000's (Host or Node) serial port?
l A NULL RS-232 serial cable is required to perform the local configuration of an IMS-4000 Host or Node.
Verify that you are using a NULL cable. A Null modem serial cable is available for purchase from Phonetics
as an accessory (part number IMS-4406).
l Make sure that your cable is connected to a serial (COM) port on your PC, not a parallel (LPT) port.
l Your PC's terminal emulation program settings may be incorrect. The serial Port settings should be as follows:
Bits per second: 9600
Data Bits : 8
Parity: None
Stop bits: 1
Flow control: None
Why can't I connect with my IMS-4000 Host using a PPP dial-up connection?
If your modem won't dial at all:
l Make sure that your Windows Dial-up Network connection is properly set up. Check that the telephone
number is properly programmed.
l Make sure that your modem is connected to a serial COM port on your PC, not a parallel (LPT) port.
If your modem dials but you can't connect with the IMS-4000 Host:
l Verify the User Name and Password settings on the Windows Dial-Up Network connection match the set-
tings programmed in your IMS-4000's Profile Setup.
l Make sure that your modem is turned on and plugged into a working telephone line.
