The factory SNMP settings are configured as follows:
Read Community: public
Write Community: private
Local/Remote changeable via SNMP:
Additionally, the default community for all four Trap Destination IP Addresses is set
to public and all configurable traps are disabled. If an address is defined without
explicit port assignment, the standard SNMP trap port 162 is assigned implicitly.
For changing the SNMP setup, please refer to chapter 5.5.7.2.2.
There are software factory defaults for some SNMP objects, please refer to the
corresponding chapters:
.application.controlMode chapter 5.9.4.3.1
.application.portTable.portEntry.poEnable chapter 5.9.4.3.9.2
.application.portTable.portEntry.poRfLimit chapter 5.9.4.3.9.6
.surveillance.trapEnableMask chapter 5.9.4.4.1
.surveillance.errorEnableMask chapter 5.9.4.4.2
4.3.5 Factory Sandar Prosan Protocol Settings
By default, the setting "Echo in Local Mode" is disabled. I.e. if the device is in Local
Mode, it does not respond to any Sandar Prosan command; please refer to chapter
5.6.1. This setting can be changed by issuing the Sandar Prosan command PME1
(chapter 5.6.3.8) or via Web Interface (chapter 5.5.7.2.3).
4.3.6 Factory Leitch Protocol Settings
By default, the setting "Echo in Local Mode" is disabled. I.e. in Local Mode, the
device responds with the Leitch Error Message to any valid Leitch command.
Furthermore the setting "Individual Switch Level Assignment" is enabled by default,
please refer to chapter 5.7.1. Both settings can be changed via Web Interface
(chapter 5.5.7.2.3).
4.3.7 Factory QEC Protocol Settings
The factory setting for the QEC serial address is 0x11 (decimal: 17).
Chapter 5.5.7.2.3 describes the change of this setting.
4.4 Communication Interface Configuration
Aside of the digital interface that permits the switching via dry contacts, two
hardware interfaces are provided for the communication with the device: a serial
interface and an Ethernet interface.
The serial interface can be used for the basic network setup and for the operation
via Sandar Prosan protocol, or via Leitch protocol, or via QEC protocol.
The Ethernet interface is used for the operation via Web Interface, via SNMP, and
via Leitch protocol or via QEC protocol through Telnet.
4.4.1 Serial Interface
The Sub-D 9 pos female connector labeled "RS 232" for the standard (3-wire) RS 232
interface is located at the rear side of the chassis; for the pin assignment please
refer to chapter 7.
