Q. Can I use the MM
™
-8802 with my older MediaMatrix
®
system that has MM DSP cards?
A. Yes. The MM-8802 includes the 9-pin D-Sub legacy port for interfacing with the original MM DSP MediaMatrix DPU card.
You must, however, have the matching legacy 9-pin cable, available only from Peavey Electronics.
Q. Is it possible to use both the legacy connection and the new CAT 5 interconnect on the same MM-8802?
A. No, only one interface can be used at a time on a single MM-8802. However, it is possible to mix the MM-8802 with older
MM-8800 Series products within the same system.
Q. Can I exceed the 6 foot cable limitation when using the legacy interface?
A. No. Even with the MM-8802, the maximum distance when using the legacy cable interface with the MM DSP DPU card is
6 feet.
Q. Can I exceed the 50 foot cable distance when using the CAT 5 interface and the MM DSP-RJ DPU card?
A. No. The 50 foot distance limitation is a total distance calculation from the MM DSP-RJ card and the nearest MM-8802.
This distance, although calculated conservatively, should not be exceeded.
Q. Can I use a Copper/Fiber media converter between the MM-8802 and the MM DSP-RJ card to get a longer cable dis-
tance with fiber optic cable?
A. No. The interface between the MM-8802 and the MM DSP-RJ DPU card is not ethernet, or other network standard. This
interface is a proprietary connection and will not work with network fiber interconnects. Connecting the MM-8802 to net-
working equipment can cause damage to the MM-8802 and/or the networking equipment.
Q. Is it possible to use a hub to daisy-chain multiple MM-8802s? I want to do this to extend the capacity of the DSP
card.
A. No. The cabling interface on the MM-8802 is not ethernet, or other network standard. This interface is a proprietary con-
nection and will not work with standard networking equipment. Connecting the MM-8802 to networking equipment can
cause damage to the MM-8802 and/or the networking equipment.
Q. Can I order the MM-8802 as an output-only box, or “short-load” the input section?
A. While it is technically possible, we do not currently offer this option. This is due primarily to the fact that the input cards
are not user-installable. There is also no "blank" card, or other way to terminate the unused inputs to the MM-8802's core
input circuitry. Therefore, all MM-8802s must be shipped with both card bays populated.
Q. I want to add an MM-8802 to an older MediaMatrix system running on Windows
®
3.1. Is this possible?
A. Yes, although some of the extended functionality that the MM-8802 provides (analog control, etc.) will not be operable.
This is true when running the MM-8802 on any MediaMatrix system prior to the Version 3.1.2 release. In this configuration,
the MM-8802 will act just like an older BoB with increased audio performance, front panel metering, etc.
Q. Are both TX and RX cables required to connect the MM-8802?
A. Yes, the “loop” must be completed between the MM-8802’s I/O ports and the MediaMatrix system.
