Troubleshooting
Although by no means exhaustive, the following table provides possible causes
behind some of the most common errors experienced when using the gateway.
Problem
Symptom
Solution
The gateway will
not turn on.
All LEDs are off and
the gateway shows
no activity.
•
Confirm that power is connected
to the correct inputs on the RS-
485 terminal block.
•
If using Power-over-Ethernet
(PoE), check that all cables are
full inserted and that the Power
Sourcing Equipment (PSE) is
powered on.
•
If firmware was being updated, it
may have been corrupted.
Unplug and reconnect the USB
cable and run the configuration
utility. Follow the utility
instructions to restore the
firmware.
No
communications
between the RS-
485 network and
the gateway.
The gateway’s RS-
485 TX and RX LEDs
are blinking slowly,
sporadically, or not at
all
•
Check connections and
orientation of wiring between the
network and the gateway.
•
Confirm that the protocol, baud
rate, parity, and address settings
on the RS-485 port match your
network configuration.
No
communication
between the
Ethernet network
and the gateway.
Communications
cannot be
established, or the
Ethernet “activity”
LED flashes only
infrequently or not at
all.
•
Confirm that the gateway is
powered (refer to section 5.1).
•
Confirm that the destination IP
address programmed into the
controller equipment or computer
matches that of the gateway, as
displayed by the Finder utility.
•
Confirm that intermediate
firewalls or routers have been
configured to allow access to the
interface via the applicable
TCP/UDP ports.
•
If attempting to access the web
server on a computer whose web
browser is configured to use a
proxy server, ensure that the
proxy server is accessible to the
computer, and that the gateway
is accessible to the proxy server.
