Setting the Hardware Base Address ID
Once you have a valid physical connection to the network port, you now must configure the port
on both ends of the network media to establish communications between the MediaMatrix
software and the CAB 4n. This is a critical configuration since you will not be able to pass audio
or enable communications without it. Please keep in mind that there are two separate settings for
successful communications on the CobraNet™ network. One is the Hardware Base Address, the
other is the “Bundle” which will be discussed in a separate section.
First things first.....The first step is to set your Hardware Base Address. Correctly setting this ID
will enable communications between the CAB 4n and its associated control panel, the “Taxi”
device within MediaMatrix software. On the CAB 4n front panel at the top left hand corner and
behind the decorative face plate there is a hardware base address switch. This switch, which is
actually 4 small rotary switches is used to set the CAB’s ID. Remove the screws from the CAB
4n face plate to gain access to the hardware base address switches. A Hardware Base Address has
4 digits. Acceptable values are in hex and range from 0001 to 7FFF. From left to right, the four
rotary switches represent your 4 digit Hardware Base Address number. If you look carefully,
there is a small arrow on each switch indicating the selected number. Using a small Phillips
screwdriver, carefully set each rotary switch to the desired number. You will feel a “click” as you
move between digits. Be careful, and do not force the switch.
The next step is to set the same address within the MediaMatrix software using the yellow CAB
device, or as I mentioned earlier, the “Taxi”. The Taxi device represents the actual hardware, and
there must be one Taxi for each physical CAB 4n. In addition to this hardware address setting, the
Taxi device includes the CAB 4n’s analog controls and the CobraNet “Bundle” assignment
control for the CAB’s audio network channel. More on that later.
Now, let's set up the hardware address within the software and establish communications between
the MediaMatrix and the CAB 4n. Refer to the picture below to set Hardware & Software
Addressing Controls. Ensure that you have the simple view shown on page 11 constructed in
NWare and compiled for these steps. (Refer to the MediaMatrix Help files for details on
MediaMatrix basics.)
Find the yellow box labeled CAB 4n the “Taxi”. Open the device by double clicking on it. Select
the CAB 4n tab, on the right hand side of this box is the Hardware Base Address “ID” Control.
This control has a 4-digit ID number
which corresponds to the 4-digit
Address ID on the actual CAB
hardware. While in Control Mode, set
the Hardware Base Address to match
(exactly) the 4-digit address you set on
the physical CAB 4n unit earlier. To do
this, click once (in Control Mode) on the
address box and type your hex based
alpha-numeric ID number. When a valid
number is entered, the green ID LED
next to the ID number should light,
indicating that the ID number you
entered is valid.
