The FASTCOM: ESCC-PCI adapter is the one of the most advanced synchronous communications adapters in the industry. The FASTCOM: ESCC-PCI supports data rates up to 10 Mbits/s¹. The FASTCOM: ESCC-PCI is a dual channel adapter, with each one being individually configurable to use HDLC/SDLC, ASYNC, or BISYNC protocols. Although similar to the HSCX adapter, the ESCC-PCI expands on our previous adapters with options that allow for:

• CRC generation either CRC-32 or CRC-CCITT polynomials (CRC-16/CCITT for BISYNC)
• CRC reset state all 1's or all 0's
• Manchester line encoding
• FM encoding (Bi-Phase Space/Bi-Phase Mark)
• Preamble transmission (with repetition)
• BISYNC operating mode, receiving and sending BISYNC formatted data
• ASYNC operating mode, receiving and sending ASYNC formatted data, in true asynchronous (no clocks, data over sampled) or isosynchronous (async data format with no over sampling)
• Software drivers are included for Windows 2000, XP, 2003, 2003x64, and Linux kernels 2.4 and 2.6
