Media Technology Systems ION8.8 - Manual (Page 19)

Note: The GUI is common to the MTS amplifier line and there will be many amplifier
parameters shown in the screen. However, these will be grayed out and can be ignored.
These will not be referred to in the descriptions below.
The default page will show 192.168.192.100, as this is the factory IP address set in the
GUI. If this is a new ION then simply press “Connect”.
Note: Each ION will attempt to obtain an IP address by DHCP on power up. This process
lasts about 1 minute. Until the DHCP period is over, it will not be possible to connect to
the ION using the GUI. If the ION has been programmed with a default address, then it
will not follow a DHCP process.
Also note that the internal UART interrupts are not enabled until after the DHCP
process, so ION parameters cannot be changed or updated during the DHCP period.
NOTE: many pages, or sections of pages, have an “UPDATE” button. If changes are made
through SNMP or TELNET, rather than the GUI, these changes will only be reflected in
the GUI after pressing UPDATE. Otherwise, the GUI would have to continuous poll every
setting and the HMI would have little processing time left over.
4.2.2 System settings
Selecting the “System” tab will open the page shown in Figure 4-3 below. The settings
are changed as follows:‐
• Ethernet IP address: This can be changed from the default address to any
address. Enter the new address and press “Set”. Note: once the IP address is
changed, the user will need to wait approximately 20 seconds for the application
to reconnect, or they can restart the application and enter the new address.
• CobraNet™ IP address: As CobraNet™ is layer 2, it does not need an IP address to
pass audio. However, for programming via SNMP the default CobraNet™ address
of 0.0.0.0 can be changed. The IP address set using the GUI is persistent.
• The CobraNet™ firmware revision is for information only. There is no setting.
New firmware should be loaded using CobraNet™ Discovery (CNDISCO).
• The parameters are set as follows:
o
The RS485 bridge status allows the user to switch the RS485 port
between local/remote ION control & monitoring or serial bridging.
o
The RS485 address refers to the address used by the RS485 port to
communicate to external devices (TBA).
o
The RS485 Master/Slave switch allows the ION to be slaved to a host
processor or act as the Master controller for the MTS wall panels or a
remote MTS ION (TBA).
o
The remote MAC address refers to the serial bridging channel settings
described in the Cirrus Logic PM25 document.
Please note that the
remote MAC address value is NOT stored in presets due to issues with the
