2. CONTACT CLOSURES – Two, single pole dry relay contacts used to activate any device that can be controlled or triggered by
a switch closure. These closures can be programmed within EZ-Tools for Momentary, Toggle and Open/Close Paired
operation. Spring loaded terminals accept wire sizes from 24 to 14 AWG. Internal relay contacts are rated at 2A/30V AC or
DC.
3. EXPANSION PORT/LOOP – Two, RJ45 jacks primarily used for looping system data to multiple MZC-88’s in expanded systems.
These jacks can also be used for connection of specialized RS485 controlled products such as the SpeakerCraft MODE
Adapter/Base for adding iPods and SpeakerCraft RSA-1.0(s) for control of multiple RS232 devices.
4. RS232 DATA I/O – One, DB9F terminal allows the MZC-88 to control certain RS232 compatible devices such as source
components and lighting systems.
5. CONTROL PORT – One, 3.5mm 4-circuit mini jack used for all Controller and Keypad programming. It also accommodates
factory firmware upgrades in conjunction with the
Firmware Upgrade On/Off Switch, located on the front panel, item 19.
See:
EZ-Tools MZC Programming Instructions
for additional information. This por also serves as a bi-directional RS-232 serial interface
allowing the MZC-88 system to be controlled by external devices.
6. PHONE PAGE IN – One, RCA jack provides input for line level audio from sources such as telephone systems, door mics or
other audio paging devices. This jack is programmable in EZ-Tools, to turn on as an ‘Event’, when triggered by the DOORBELL/
STATUS IN Jacks, item 8.
7. VIDEO PAGE IN – One RCA jack provides input for composite video from doorbell paging systems, cameras or other
composite video sources. This jack is programmable in EZ-Tools, to turn on as an ‘Event’, when triggered by the DOORBELL/
STATUS IN Jacks, item 8.
8. DOORBELL/STATUS IN 1 & 2 – Two, 3.5mm mini jack trigger inputs work in conjunction with the PHONE and VIDEO PAGE IN
jacks, items 3&4. When triggered, the Page Inputs can be turned on in selected zones as programmed in
EZ-Tools. If Paging
is not required, these jacks can also be programmed as STATUS INPUTS for power management of Source or Zone
components.
POLARITY: TIP= +V; SLEEVE=GND. INPUT VOLTAGE: 3-30V AC or DC to trigger the ON condition. Voltage must
drop below 1V AC or DC for OFF.
9. COMMON IR OUTPUT – One, 3.5mm mini jack outputs all IR commands from IR sensors and Keypads regardless of zone origin.
POLARITY: TIP=SIGNAL; SLEEVE=GND.
10. HI/LO SWITCH – One, two position switch, sets high or low IR power output to the Common IR Output jack. Set to the LO
setting when driving standard low power emitters (SpeakerCraft IRE-1.0, 2.0, 3.0 and 4.0). Set to
HI when driving a high power
emitter (SpeakerCraft IRE-5.0 Blaster) for teaching IR commands into learning remotes.
HI OUTPUT: 110mA; LO OUTPUT:
13mA.
CAUTION:
The
HI position will smoke low power emitters!
11. COMMON STATUS OUT – One, 3.5mm mini jack will go high (+12V DC) when any zone is turned ON and will go LOW (under 1V
DC) when the last zone is turned OFF.
POLARITY: TIP=+12V DC; SLEEVE=GND. MAX OUTPUT: 100 mA at 9.5V DC.
12. STATUS IN – Six, 3.5mm mini jack trigger inputs primarily used for power management of common source components that do
not have discreet IR ON/OFF codes.
POLARITY: TIP=+V; SLEEVE=GND. INPUT VOLTAGE: 3-30V AC or DC to trigger the ON
condition. Voltage must drop below 1V AC or DC for OFF.
13. FM/AM/75Ω – One, F-type terminal, connects to a SpeakerCraft HED-1.0 Masthead Amplifier. The HED-1.0 should be located
away from the system components to reduce RF interference and improve reception. FM Dipole and AM Loop antennas
connect to the HED-1.0.
CAUTION: Do not connect an antenna directly to this terminal. There is DC voltage present to power
the HED-1.0. This voltage will interfere with antenna performance and possibly cause electrical short if not terminated
properly.
14. IR OUT (Source) – Six, 3.5mm mini jacks, one per Source, output IR commands to external common source components.
When a source is selected, from a keypad or remote control, IR commands are routed directly to that source. This allows
selective control of multiple same-brand, same-model source components (multiple Satellite Receivers, DVD Players etc).
POLARITY: TIP=SIGNAL; SLEEVE=GND.
15. IR LOOP – Six, 3.5mm mini jacks, one per Source, provide connections for an IR signal path for external common source
components, when using multiple MZC-88’s in expanded systems. i.e. If using two MZC-88s, the SOURCE IR OUTS on the MZC
Slave unit would connect to the appropriate SOURCE IR LOOPS on the MZC Master unit to pass Source IR commands
between controllers from expanded zones. The IR OUTS on the Master connect to IR EMITTERS attached to the source
components for source IR control from all zones.
POLARITY: TIP=SIGNAL; SLEEVE=GND.
16. L, R & V INPUT (Source Left/Right Audio/Video Input) – Eighteen RCA jacks, three for each Source, provide left and right
line-level audio and composite video signal inputs for up to six external common source components.
17. L, R & V LOOP (Source Left/Right Audio/Video Loop) – Eighteen, RCA jacks, three per Source, provide buffered left and right
line-level audio and composite video outputs that are typically used to loop Source Audio signals to additional zone inputs
on Slave MZC-88’s in expanded systems. i.e. The L, R, V LOOP on the MZC Master would connect to the appropriate L, R, V
INPUT on MZC Slave 1. Slave 1 would then loop to Slave 2, etc. These outputs can also be used to drive local components,
such as a local surround receiver, when not used for expansion.
