Important: TURN THE UNIT OFF before connecting to the RS232/RS422 (F) or Crown Bus

(H)connectors. TURN THE UNIT OFF before changing the settings of the IQ Address (M), Baud Rate & Parity (N) or Communication Standard (O) switches.

optional shield for the Crown Bus cable. Only the shield of the input cable should be connected. Shielded wire will reduce the total distance a Crown Bus loop can be run, but shielding may be neces- sary to reduce interference with certain kinds of audio cables. (Section 3.2)

Crown Bus Input/Output Connector

A4-pin removable barrier block plug is used for input and output connection to the Crown Bus. The pins are numbered backward from right to left (as you face the back panel of the unit). Pin 1 is input negative (–), pin 2 is input positive (+), pin 3 is output negative (–), and pin 4 is output positive (+). (Section 3.2)

Main Audio Outputs

A3-pin removable barrier block plug is used to connect to the main output of each channel. These outputs can also be connected to the stack inputs

(B) of other mixer/multiplexers to make a 12x2 (or larger) mixer. (Section 3.3.2)

Auxiliary Bus Audio Outputs

A3-pin removable barrier block plug is used to connect to the bus audio output of each channel. The bus outputs are isolated switchable outputs that can be turned on when needed by the IQ System. This allows many multiplexers to be tied together on the same bus without loading down the outputs. (Section 3.3.2)

Audio Inputs

A3-pin removable barrier block plug is used to connect to the input of each of the six audio inputs. The input gain control (E) and the input selector (K) of each one should be set to match the input signal level. These inputs can also be connected in parallel

with the inputs of other mixer/multiplexers to make a 6x4 (or larger) mixer. (Section 3.3.1)

Input Selector

Athree-position input selector accommodates dif- ferent input signal levels. The three settings are L for line-level input, M for mic-level input, and P for mic-level input with phantom power. The P setting supplies 44 volts DC for phantom-powered mics.

IQ Address

An 8-section DIP switch is used to set the IQ ad- dress of the unit. The unit must be given a unique IQ address so it can be independently controlled and monitored by a the system. It must also be set properly if the unit is to be used in a Crown Local Net. Two or more IQ components of the same type should NEVER have the same address on the same Crown Bus loop. (Section 3.2) Important: The IQ address should only be set with the power cord disconnected from the AC supply.

Baud Rate & Parity

A 6-section DIP switch is used to set the baud rate and parity for RS232/RS422 serial communication. This is only necessary when the DB25 connector (F) is used. Important: The baud rate should only be set with the power cord disconnected from the AC sup- ply.

Communication Standard

A communication standard switch which allows the unit to be configured for the RS232 or RS422 com- munications. (Sections 3.1³3.1.1) Important: The communication standard should only be set with the power cord disconnected from the AC supply.

AMB-5, MPX-6, SMX-6 specifications

The Crown SMX-6, MPX-6, and AMB-5 represent a remarkable evolution in material handling and warehouse management technology. These models are part of Crown's extensive portfolio designed to enhance efficiency, reliability, and operator comfort in various industrial environments.

Starting with the Crown SMX-6, this heavy-duty reach truck is engineered for superior performance in tight spaces. It features an optimized chassis that provides improved stability and maneuverability, making it perfect for narrow aisles and dense storage environments. The SMX-6 is equipped with Crown's state-of-the-art Access1 Door, which enhances operator safety and accessibility to the vehicle's controls. Its innovative lift system allows for higher lifting heights with precision and control, reducing load sway during operation. Additionally, the advanced ergonomic design of the operator's compartment minimizes fatigue, promoting longer and more productive shifts.

The Crown MPX-6, on the other hand, is designed primarily for order picking in warehouses. Its low level order picker design helps increase productivity across the picking process. This model features Crown's unique Power Steering technology, which provides precise control and reduces operator effort, making it easier to navigate through aisles and around corners. The MPX-6 also includes integrated LED lights that provide optimal visibility in dimly lit environments, while its lift and lowering functions offer fast and responsive operation. The advanced control system helps simplify training for new operators, promoting safety and efficiency on the warehouse floor.

The Crown AMB-5 is another standout model, known for its versatility and adaptability in various material handling scenarios. This model is engineered for both indoor and outdoor operations, allowing businesses to maximize versatility without compromising on performance. The AMB-5 is equipped with advanced lithium-ion battery technology that offers rapid charging capabilities and longer operational life compared to traditional lead-acid batteries. This feature is a game-changer for operations that demand high uptime and minimal downtime. The vehicle also features a compact design, making it easy to operate in confined spaces while still delivering robust lifting capacities.

In summary, the Crown SMX-6, MPX-6, and AMB-5 are exemplary models in the field of material handling, each offering a blend of innovative features, advanced technologies, and thoughtful design aimed at enhancing operational efficiency, safety, and operator comfort. These machines exemplify Crown's commitment to providing high-performance solutions adaptable to the ever-evolving requirements of modern warehousing and logistics.
