Engineered for seamless integration with the QUESTRA platform, it enables centralized configuration, remote management, and reliable communication with a wide range of third-party devices. Its ultra-compact form factor makes it an ideal solution for installations where space is limited but flexible, network-enabled control is essential.\u003c\/p\u003e\n\u003cp\u003eOffering extensive connectivity, the SGP42 features four configurable digital GPIO ports that can operate as dry-contact inputs for buttons and presence sensors or as TTL-level outputs for indicators and external devices. It also includes two Normally Open (NO) relay outputs and an RS232 interface with a 3-pin terminal block, enabling control of serial equipment and automated functions such as media playback, projector operation, lighting activation, and other building control tasks. These versatile interfaces allow users to create customized automation sequences tailored to the needs of meeting rooms, classrooms, hospitality spaces, and integrated AV systems.\u003c\/p\u003e\n\u003cp\u003eDesigned for dependable operation and straightforward installation, the DSGP42 supports Power over Ethernet (PoE) while also offering a 12–24 VDC terminal block input for optional external power. Integrated status LEDs provide clear monitoring of GPIO, relay, and RS232 activity, simplifying setup and troubleshooting. Measuring just 95 mm × 68 mm × 17 mm, the device can be conveniently mounted on surfaces, inside technical enclosures, or directly onto walls using the included mounting accessories. Combining compact design, flexible I\/O capabilities, and seamless QUESTRA integration, the SGP42 delivers a practical and reliable solution for modern automation applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCoating: \u003c\/strong\u003ePowder-coated\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eColor: \u003c\/strong\u003eBlack\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSerial baud rates: \u003c\/strong\u003e2,400 \/ 4,800 \/ 9,600 \/ 14,400 \/ 19,200 \/ 38,400 \/ 56,000 \/ 57,600 \/ 115,200 bps\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRS-232 communication mode: \u003c\/strong\u003eFull duplex\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRS-485 communication mode: \u003c\/strong\u003eHalf duplex\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConnectivity type: \u003c\/strong\u003eEthernet\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLAN connector: \u003c\/strong\u003eRJ-45 socket\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLAN data rate: \u003c\/strong\u003e10\/100 Mbit\/s\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExternal control interface: \u003c\/strong\u003eIR transmitter (IR blaster)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIR blaster output level: \u003c\/strong\u003e5 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating voltage: \u003c\/strong\u003e100–240 V AC \/ 50–60 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower supply type: \u003c\/strong\u003eSwitched-mode power supply (SMPS)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRated power: \u003c\/strong\u003e0.48 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmbient temperature: \u003c\/strong\u003e0–40 °C\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum humidity: \u003c\/strong\u003e90% (non-condensing)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eESD protection (non-contact): \u003c\/strong\u003e8 kV (IEC 61000-4-2)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eESD protection (contact): \u003c\/strong\u003e4 kV (IEC 61000-4-2)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWidth: \u003c\/strong\u003e95 mm (3.74 in)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeight: \u003c\/strong\u003e17 mm (0.67 in)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDepth: \u003c\/strong\u003e68 mm (2.68 in)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight: \u003c\/strong\u003e181 g (0.18 kg \/ 0.40 lbs)\u003c\/p\u003e","brand":"LD Systems","offers":[{"title":"Default Title","offer_id":47727352152317,"sku":"H-LDSY-LDSSGP42","price":239.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/2308\/3005\/files\/2111217.jpg?v=1781726390","url":"https:\/\/hollywooddj.com\/products\/ld-system-sgp42-ethernet-i-o-expansion-interface","provider":"Hollywood DJ","version":"1.0","type":"link"}
