Intellicon-NT960/PCI ACM/16

The ACM/16 (Asynchronous Communication Module) is an external module that connects to the NT960/PCI Host Adapter via a high speed 37 pin external bus cable. Figure 2 shows a top view of the ACM/16. The ACM/16 offers the following features:

„16 asynchronous RS-232-C serial ports.

„Four CLCD1400 RISC-like quad UARTS c/w 12 bytes of receive and 12 bytes of transmit FIFO for each port.

„Each port is individually programmable for baud rates up to 115 Kbps.

„Each RS-232 port supports the following signals: TxD, RxD, DTR, DSR, RTS, CTS, DCD, RI.

„Support for 5 to 8 data bits per character plus optional parity; odd, even, no or forced parity; and 1 or 2 Stop Bits.

„Includes a 37 pin bus cable and an external power supply.
