Verify that the ELK-IP232 is powered up and connected to the network.
Wait 1 minute after powering up the ELK-IP232 for the initialization process to
complete before the utility can "Find" the ELK-IP232.
Verify all cable connections and check to see if the green LED on the RJ45
connector is blinking, indicating network traffic.
Use the "DEFAULT" jumper to force the DHCP/IP address setting to known
values. For instructions on this process, see page 13.
If the network router is not serving IP addresses, or the ELK-IP232 is set to a
static address, use a crossover cable to connect directly from the PC to the ELK-
IP232. This will require making some changes to the network setup of the PC to
allow the PC and the ELK-IP232 to be in the same subnet.
If there is a router/firewall between the PC and the ELK-IP232, or if the PC is
running a firewall, it must not block port 2362.
Using the ELK-IP232 Configuration Utility, click "Search" to verify the ELK-IP232
is working and to determine its IP address and IP Port to use. If it is not found,
refer to the troubleshooting steps above.
Click "Configure" and note the IP address and IP port number. Verify the remote
connecting device is connecting to that IP address and port number. If there is a
router/firewall between the remote device and the ELK-IP232, it must not block
the IP port.
Follow the same troubleshooting steps for a local network connection above.
Verify router settings- the router must port forward the configured IP port.
If using a DDNS service, any changes to the "dynamic" name may require time to
propogate through the entire internet system. Depending on the service, this
could take 1 or 2 days.
Use the ELK-IP232 configuration utility to note the baud rate and flow control
settings. Verify the connected serial device is configured accordingly.
The connected serial device must be set for 8 data bits, no parity, and 1 stop bit.
If flow control is enabled, try temporarily disabling it on both ends.
If hardware flow control is required, verify the cable is wired for it. Test the cable
by connecting it between two other devices and verifying they communicate
correctly.
Verify whether a standard straight-through or null modem cable is required. To
connect the ELK-IP232 to a PC, a null modem cable is required. To connect the
ELK-IP232 to an Elk-M1, to most audio/video systems, and to most other similar
devices, a standard straight-through cable is needed.
