Expanding the easy way with the MM-8802
There are two additional I/O blocks within the X-Ware software specifically for the MM-8802 break-out box. In addition to
providing the I/O expansion, these blocks include the controls for the MM-8802. Using the MM-8802 with these I/O blocks is
the easiest way to expand the X-Frame 88. The Expansion Ports provide connectivity for up to two MM-8802 break-out boxes.
Each MM-8802 provides eight analog inputs, eight analog outputs, eight CV control ports and eight TTL logic output ports.
Adding two to a single X-Frame 88 makes the complete package a 24x24 system in three rack units! The figure below shows
how the expanded system is connected using standard CAT 5 cables.

Connecting the MM-8802 is a simple, direct connection. Remember, there are two Expansion Ports, each with an TX and an
RX connector. To add an MM-8802, connect a CAT 5 cable from Expansion Port A, TX (TX A) to the MM-8802 RX connector.
Return a second CAT 5 cable from the MM-8802 TX connector to the X-Frame 88 RX connector, also on Port A (RX A). Audio
is transmitted via the TX connector, and recieved via the RX connector. This connection is a "loop", so both cables must be
connected for proper operation. Repeat the process for the second MM-8802. If the connection is successful, the LED located
next to each RX connector will be illuminated at each unit. If this LED is off on either unit, it could indicate a problem with
the cabling.
To make this work, you need to configure the I/O in software by using the special "BoB" I/O blocks. These blocks include func-
tionality specific to the MM-8802 and integrates the MM-8802's analog I/O and the digital Link to the X-Frame 88.
Essentially, the BoB I/O blocks are just expanded versions of the Link I/O blocks shown in Fig. X. To connect two MM-8802s
as in our example above, we would need to configure a view file that includes all of the analog I/O and the interconnectivity
between the boxes (the Expansion Ports). The example in Fig X shows how this would be accomplished. Remember, the I/O
and Link connectivity between the X-Frame 88 and the MM-8802s is built-in by using the BoB I/O blocks. There is no need to
use separate Link I/O blocks when using the MM-8802.
