Digital MultiTasker grows its skill set
Altinex has introduced the MT312-104 control card and MT322-105 and MT322-107 distribution cards for use with its MT302-201 Digital MultiTasker. The MT312-104 is designed for use with touchscreen control panels and provides multiple ports for directing a wide range of A/V equipment, while the MT322-105 and MT322-107 distribute AC power from a single source to multiple outlets, which can be connected to any type of audio or video equipment.
Offering command of serial and IR devices, the MT312-104 control card boasts two relays and two sensor inputs. These relays can control external equipment, such as screens, while the sensor inputs trigger events based on voltage levels supplied by motion, heat, light and RF sensors. The sensor connector provides two voltages, +12VDC and +24VDC, for powering external sensors.
The MT312-104 can also supply information from third party controllers over an Ethernet port. By connecting to the MultiTasker enclosure’s IP address, it is possible to check the status of the replays, the input status of the sensor inputs based on trigger levels, or request RS-232 data from devices connected to the RS-232 ports.
Additionally, IR codes can be stored in its internal memory, allowing for direct control of external IR devices. An IR room receiver such as the manufacturers AC301-103 can be used to pass-through IR signals from remote controls to devices connected to one or both of the controller’s IR outputs.
Multiple control cards can also be used within a single MT302-201 enclosure, allowing for increased expandability and control of A/V systems with unlimited capacity.
Meanwhile, both the MT322-105 and MT322-107 power distribution cards have built-in current measuring circuits to detect load levels. The value of these loads may be read over the IP port and an alarm can be triggered when power is exceeded.
The MT322-105 contains an IEC male connector for the AC supply input and standard NEMA 5-15R power receptacles for the three outputs. Built in sensors alert the user by flashing the LEDs when the load exceeds 9.5A as well as a warning message over the IP port when the current draw approaches the maximum 10.5A limit. The MT322-107 international version contains one IEC male connector for the AC power supply input and three IEC 320 female outlets. With this model, sensors alert the user when the load exceeds 8.5A and a warning message is sent over the IP port when the current draw approaches the maximum 10A limit. Both cards have safety provisions that cause the cards to automatically start turning outlets off should the system approach maximum power draw. A message informing the user that outputs are being shutdown is sent to the MT302-201 Digital MultiTasker’s IP port.
Both distribution cards are able to turn audio or video equipment on and off in a sequential order, which may be defined using IP protocol commands. The time delay between switching is also programmable from 0-50s. The threshold level for the on/off detect feature is adjustable to accommodate different loads and determine when A/V equipment is on or off. This feature allows the control system to determine if the device is on or off by the amount of current it draws.
