IP-OCTALPLUSTTL is a single-wide IndustryPack that implements eight TTL-level asynchronous serial ports, each with inverted RXD, TXD, RTS, and CTS signals. In addition, two ports have DCD, DTR, DSR, and RI signals. Ther serial ports are implemented with two Exar ST16C654 quad UARTs. Each channel has two 64-character FIFOs to allow longer interrupt servicing latencies.

  • All signals are inverted
  • 64-character FIFOs on all receivers and transmitters
  • Eight TTL-level ports
  • Support for RXD, TXD, RTS, CTS, and GND on each port
