The SBC488A programmable single board computer boasts a fully integrated C development environment and an IEEE 488 General Purpose Interface Bus (GPIB) controller to provide OEM's with flexible rapid instrument development capabilities without the associated time and expense of developing a GPIB controller for their products. Specifically designed as a low-cost turnkey solution, the board is suited for a broad range of power supply, RF test equipment, and laboratory instrument applications where IEEE 488, RS-232/RS-485 control is required. The GPIB may be found in various test environments, and is commonly used to control such devices as RF signal analyzers and switching arrays, digital voltmeters, data loggers, programmable power supplies, oscilloscopes, logic analyzers, function generators, plotters and printers. Featuring a Zilog Z180 based processor with speeds of 9.216MHz or 18.432MHz, EPROM, SRAM, and EEPROM, the SBC488A features a Real Time Clock (RTC) as well as battery backup. Its IEEE 488 interface provides talker, listener and controller functions, while two serial ports support RS-232 and RS-485 communications. Measuring 165 x 102 mm, the board's power requirement is 2 W at 7 to 24 Vdc.
