A system (40) is provided for adapting one of a number of different types (42, 44, 46, 48) of instruments to a common protocol. Each instrument (42, 44, 46, 48) has a serial input-output (I/O) port (162, 262, 362, 462), a control for the serial I/O port (162, 262, 362, 462), and an operating power supply connection (160; E2, E4, E1, E3; E2, E4, E1, E3; E2, E4, E1, E3) to the instrument (42, 44, 46, 48). The system (40) includes a type (124, 126, 128, 130) of housing for each different type (42, 44, 46, 48) of instrument. Each type (124, 126, 128, 130) of housing includes openings (192, 193, 194, 196, 198; 292, 293, 294, 296, 298; 392, 394, 396, 398; 492, 494, 496) through which selected controls and displays (184, 185, 186, 188, 190; 284, 285, 286, 288, 290; 363, 384, 386, 390; 484, 486, 490) of a respective one (42, 44, 46, 48) of the instruments are accessible. Each housing includes connectors (154, 156; 254, 256, 261; 354, 356, 361; 454, 456, 461) for coupling to a respective type (42, 44, 46, 48) of instrument's serial I/O port (162, 262, 362, 462) and to a respective type (42, 44, 46, 48) of instrument's power supply connection (160; E2, E4, E1, E3; E2, E4, E1, E3; E2, E4, E1, E3).
