Data Interfaces | |||
Your choices are... | |||
GPIB / HPIB | General purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It is also known as IEEE 488 or HPIB, and is electrically equivalent to IEC 625 bus. | ||
RS232 / RS485 | RS232 and RS485 are standard serial interfaces. | ||
USB | Universal serial bus (USB) is a four-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. | ||
Ethernet | Devices are able to transmit data over Ethernet or TCP/IP. | ||
D/A Signal | Digital to analog (D/A) signal. | ||
Other | Other unlisted, specialized, or proprietary interface type. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
