Extron electronic MLC 62 IR D manual Port B IR/S

AHost/Config port — This bidirectional RS-232 serial port can be used for

configuration and firmware updates in the same way as the USB port (G in the

“Front and Left Side Panels” section, earlier in this section). The baud rate is 9600 bps. This port can be used as a backup for the USB Configuration port (although you cannot power a device through it).

BDigital Input port (RS models only) — This port enables the MLC to monitor devices such as push buttons, switches, motion sensors, and moisture sensors and provides an additional way to trigger functions on the MLC. Connect a switch or a sensor to this 2-pole captive screw connector to initiate commands via the MLC to the display device, switcher, or other room devices such as lights or a motorized screen.

CRelay ports (RS models only) — These relays allow control of room devices such as motorized screens, lights, and projector lifts. They are normally open relays and are rated at 24 V, 1 A. Low-power devices can be connected directly to the relay ports; devices requiring more than 24 V can be connected through a third-party low-voltage controller (LVC).

DIR/S or IR port — This port provides unidirectional communication to control a switcher or a display via RS-232 or IR. For IR control, one or two IR emitters can be connected with a maximum of 50 feet (15 m) distance from port to emitter.

•RS models: On all MLC 60 Series RS models, this port is labeled “Port B IR/S.” It can be set up via the configuration software to send out unidirectional RS-232 (the default) or IR commands. In the Configuration software, this port is called

Port B (IR/S)

•MLC 62 IR D: On the IR-only model, this port is labeled “Port A IR” and issues only IR commands. In the Configuration software, this port is called Port A (IR).

ERS-232 port (RS models only) — This serial port, labeled “Port A RS-232,” provides unidirectional communication to control a switcher or a display via RS-232. In the Configuration software, this port is called Port A (RS-232).

FPWR (power) connector — Connect the supplied 12 VDC, 1 A power supply (or any other power supply capable of providing 12 VDC) to this 2-pole captive screw connector.

CAUTIONS: • The power supply must not be permanently fixed to the building structure or similar structures.

•The power supply must not be located within environmental air handling spaces or the wall cavity.

•The installation must be in accordance with the applicable provisions of the National Electrical Code ANSI/NFPA 70, Article 725 and the Canadian Electrical Code, Part 1, Section 16.

•The power supply must be located within the same vicinity as the Extron AV processing equipment in an ordinary location,

Pollution Degree 2, secured to a podium, a desk, or an equipment rack within a dedicated closet.

•Always use a power supply specified by Extron for the MLC. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the MLC.
