If the Web Interface does not react after a restart, then the ARP (Address Reso-
lution Protocol) cache of your computer may have to be cleared by opening a
command window and by typing: "
arp –d
<CR>
" (
<CR>
stands for hitting the "
Enter
"
or "
" key on the keyboard).
If –for any reason– neither a reset nor a power cycle of the device restores all
functionality, a reset to factory defaults is to be considered:
Usually, the factory settings (chapter 4.3) can be restored via Web Interface
(chapter 5.5.7.4.1). If the device is not accessible via Web Interface, the factory
settings can be applied in the following manner:
Press and hold the "
Reset
" push button of the CPU module e.g. by using a
ballpoint pen.
The yellow LED on the "
Ethernet
" connector of the CPU module starts to blink
after ~20…50 seconds, indicating that the "
Reset
" button can be released.
Now a reset follows resulting in a device with restored factory settings.
4.3
Device Factory Settings
The product is delivered with factory settings as described in the following.
It is possible to restore these settings, please refer to chapter 4.2.6.
4.3.1
Factory Settings for Sensing Switch Modules
All sensing switch modules provide RF level monitoring functionality. I.e. for both
input ports, the aggregated signal power level of the RF signal is measured and
compared with an RF threshold level. If the RF level is below the RF threshold level,
an event is triggered which is indicated e.g. via Web Interface. The factory setting
for the RF threshold level for each input port of a sensing switch module depends
on the lower limit of the applied sensing switch module:
RF threshold level:
(
20 dB above lower limit
)
For example, if the lower limit is -50 dBm, the factory setting for the RF threshold
level is -30 dBm. The RF threshold level can be adjusted for each input port via the
Web Interface (please refer to chapter 5.5.4.2) or via SNMP (chapter 5.9.4.3.9.6) in
a range which depends on the applied sensing switch module.
Note that if an exchange module is inserted in a slot of the DEV 1953, the new
module inherits the stored settings of this slot (after a device reset).
4.3.2
Factory Communication Protocol Configuration
The factory setting for the Communication Protocol Handler (CPH) is the Leitch
protocol, i.e. the serial interface configuration are the standard serial interface
configuration settings, please refer to chapter 4.4.1.1.
Chapter 5.5.7.2.3 describes the change of the protocol assignment.
4.3.3
Factory Network Settings
The factory network settings of the device are:
IP-Address:
192.168.0.11
Netmask:
255.255.255.0
Gateway:
192.168.0.99
For changing the network setup, please refer to chapters 4.4.2.2 & 5.5.7.2.1.
