A. LED – Indicates that this Module is activated (active or bypass).
B. DIP Switch – Using binary code, designates Component Selection Numbers for each
Switching Module (e.g. Module 2 in CD Chain; Positions 8–15). See Appendix A for DIP
Switch setting instructions.
C. Control Cable Connectors – Supplied Control Cables are connected to these to connect
the first Switching Module in a Chain to the MVP Control Panel, then connect Module to
Module within a Chain.
D. Component Turn-On Relays – On 1214, these relays switch power to selected
components. Not present on 1210.
E. Low-Level Bus Connectors – These connectors route signals from Module to Module
within a Chain and from Chain to Chain to form the signal bus. They are labeled “In” at the
top and “Out” at the bottom for convenience only – as with all MTi Switching Modules, the
connectors are parallel; either set may be used for incoming or outgoing signals.
F. Low-Level Connectors – Provides connection points for component inputs and outputs.
G. Component Turn-On Strip – Provides connection point for 12V DC power to Module and
distributes power to components when they are selected. Not on 1210 .
H. LED Turn-On Strip – For non-lighted components, LEDs can be mounted nearby to indicate
activation. When a Position is selected, a contact is made and the Turn-on Strip provides
power to the LEDs.
I. Input/Output Designation – Provides a space for labeling the Module with correct
information for each set of component connection points (e.g., DECK OUT, for the outputs
for the Tape Deck Chain).
J. Module/Chain Name/Number – Provides a space for labeling Module with its Chain name
and designation (e.g., CD 2, for the second Module in the Compact Disc Player Chain).
NOTE: It is advisable to write component numbers on top of the corresponding yellow relays next to each
component’s connection terminals with an indelible pen, as illustrated in Figure 34, page 63.
