If contact is established with the unit, but the IPL EXP web pages cannot be accessed
by your browser program, verify (via an Internet network options or preferences menu)
that your browser is configured for direct network connection and is not set up to use a
proxy server.
Device Control Connections and Configuration
•
Verify that ports are wired correctly and that ground (earthing) wires are connected to
the proper pins on the control processor and, if applicable, on the controlled device.
•
Ensure that each IR emitter head is placed adjacent to or directly over the IR pickup
window on the controlled device.
•
Verify that the appropriate drivers were used while creating the configuration file and that
the correct commands and signal types (IR, RS-232, Ethernet) are associated with the
appropriate ports on the control processor and on the other devices.
•
For digital input and output connections, verify whether the application requires the
+5 VDC pull-up resistor within the IPL EXP for TTL circuits, and use the software to
check whether it is selected within the configuration.
•
Verify that input current at any digital input or output port does not exceed 250 mA.
eBUS Connections and Configuration
•
Verify that the eBUS ports are wired correctly and that ground (earthing) wires are
connected to the ground pins on every device in the system. Connectors should be
wired the same at each port.
•
Check for eBUS address conflicts (see the Toolbelt Help File). Ensure that each device
in the system has a distinct, individual bus ID address and that no device is set to
address zero. When an eBUS address conflict exists:
•
The devices that share an address do not function.
The other devices work correctly.
•
NOTE: If a device bus address is set to zero, it is not recognized by the EXP.
•
If the IPL EXP 200 does not recognize any connected devices and if the eBUS port is
in an overload state (the EXP can be configured to monitor the state of the port), power
consumption at the eBUS port is too high.
Use one of these methods to restore the eBUS port to normal mode:
•
Remove eBUS devices one at a time from the system until the overload no longer
occurs.
Add supplemental power supplies to the system.
•
See the eBUS Technology Reference Guide (available at
www.extron.com/ebus_tech_ref) for details.
•
Once overload conditions are resolved, the eBUS devices resume functioning and are
again recognized by the EXP.
