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.
