The IP-OCTAL-485 IndustryPack module implements eight EIA-485 asynchronous serial ports, each with DX+, DX- balanced pair signals and a ground. Serial ports are implemented with the Signetics SCC2698B octal UART. Each channel has a 3-character FIFO on its receiver to allow longer interrupt servicing latencies. Eighteen programmable baud rates up to 38.4 kb/s, and programmable bit length, parity, and stop bits are supported.
- Programmable baud rates in 18 steps up to 38.4 kb/s
- Four 16-bit timers
- Support for DX+, DX-, and GND on each channel
- 3-level FIFOs on all receivers
- 8 EIA-485 ports on a single-wide IndustryPack
