Intellicon-NT960/PCI ACM/Flex16

The ACM/Flex16 (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 4 shows a top view of the ACM/Flex16. The ACM/Flex16 offers the following features:

„16 asynchronous RS-232-C and/or RS-485/422 and/or 20mA Current Loop serial ports

„The RS-232, RS-485/422 and 20mA Current Loop electrical interfaces are on field upgradeable Serial Line Interface Modules (SLIM). This allows you to run different line interfaces on the ACM/Flex16 at the same time.

„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.

Note: ports 3, 4, 7, 8, 11, 12, 15 and 16 do not support the RI signal.

„Each RS-485/422 port supports the following signals: TxD, RxD, RTS, CTS.

„Each 20mA Current Loop port supports the following signals: TxD, RxD.

„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.

„Up to eight ACM/16's, ACM/16RJ’s and/or ACM/Flex16’s can connect to an Intellicon-NT960/PCI Host Adapter providing up to 128 serial ports.
