A low-force helix ( LFH-60 ) is a 60-pin electrical connector (four rows of 15 pins) with signals for two digital and analog connectors. Each of the pins is twisted approximately 45 degrees between the tip and the plastic frame which holds the pins in place. Hence "helix" in the name.
7-531: The DMS-59 is a derivative of the LFH60. The LFH connector is typically used with workstations , because it can connect a single computer graphics source to up to four different monitors. The standard interface is a 60-pin LFH connector with two breakout VGA or DVI cables. This system provides users with flexibility for a variety of display configurations, though forsakes standard DVI or VGA connectors. This renders
14-444: A low-profile card support two high resolution displays, and a full-height card (with two DMS-59 connectors) up to four high resolution displays. The DMS-59 connector was used by e.g. AMD ( AMD FireMV ), Nvidia and Matrox for video cards sold in some Lenovo ThinkStation models, Viglen Genies and Omninos, Dell , HP and Compaq computers. DMS-59 connectors also appeared on Sun Computers. Some confusion has been caused by
21-466: A single monitor, delivering 9.2 million pixels of resolution (3840 × 2400). This system provides large amounts of detailed information for professional applications such as aerospace and automotive visualization , computer aided design , desktop publishing , digital photography , life sciences , mapping, oil and gas exploration, plant design and management, satellite imaging , space exploration , and transportation and logistics . The LFH connector
28-431: Is four pins high and 15 pins wide, with a single pin missing from the bottom row, in a D-shaped shell, with thumbscrews. As of December 2020 , this adapter cable was listed as obsolete by its primary vendor Molex . The advantage of DMS-59 is its ability to support two high resolution displays, such as two DVI Single Link digital channels or two VGA analog channels, with a single DVI-size connector. The compact size lets
35-526: Is used in some Cisco routers and WAN Interface Cards. DMS-59 DMS-59 ( Dual Monitor Solution, 59 pins ) was generally used for computer video cards . It provides two Digital Visual Interface (DVI) or Video Graphics Array (VGA) outputs in a single connector. A Y-style breakout cable is needed for the transition from the DMS-59 output (digital + analogue) to DVI (digital) or VGA (analogue), and different types of adapter cables exist. The connector
42-542: The LFH connector unusable without an adapter. It's also used in HDCI (High Definition Camera Interface) used in Polycom HDX video conferencing systems. Using the LFH interface requires a graphics card with multi-monitor capabilities and an LFH port. NVIDIA and Matrox used to manufacture such cards. Another application of LFH capabilities is manufactured by Matrox . The Matrox card outputs via two LFH cables to
49-659: The fact that vendors label cards with DMS-59 as “supports DVI”, but the cards have no DVI connectors built-in. Such cards, when equipped with only a VGA connector adapter cable, cannot be connected to a monitor with only a DVI-D input. A DMS-59 to DVI adapter cable needs to be used with such monitors. The DMS-59 connector is derived from the LFH-60 Molex low-force helix connector, which could be found in some earlier graphics cards. These ports are similar to DMS-59, but have all 60 pins present, whereas DMS-59 has one pin (pin 58) blocked. A connector plug with all 60 pins (such as
