Electro Standards Laboratories 3-Channel DB9 A/B Switch Model 9449

Description
With each of its three channels, the Model 9449 DB9 RS422 A/B Switch allows the user to access two DB9 devices connected to its A and B ports with one DB9 device connected to its COMMON port. The three channels are switched simultaneously via a knob located on the front panel. See the application diagram below. Features: Each of three channels allows quick connection to any one of two devices from one COMMON device. Simultaneously switches all three channels via front-panel rotary switch. High quality sealed switch with self-wiping low impedance contacts. All 9 pins of the DB9 interface are switched. Ideal for RS422 applications that have a DB9 connector interface. Transparent to data speed and format. Improves computer network efficiency by allowing sharing of peripherals. Eliminates the need to plug and unplug cables. Attractive anodized black box packaging provides EMI/RFI shielding. Rackmount configuration is standard, height 1U (1.75") Lifetime guarantee against manufacturing defects.
