Multiport/2 Base Card P/N 16F2200

There are no visible reference designators on the board. The designators shown here are made up.

Z0803606VSC Z-CIO datasheet
Z0803008VSC Z-SCC datasheet

Each ARTIC Multiport/2 is configured with an Intel 80C186 processor, 512 KB to 1 MB of memory, and the ability to expand the number and type of communications ports using a variety of electrical interface boards (EIBs) and cables. Any single port can operate up to 38.4 Kbps, and, when expanded with an eight-port EIB, all ports can communicate at 9600 bps.

LED Indicator

A light-emitting diode (LED) indicator provides a visual status of the watchdog timer status and error status. The LED turns on when the watchdog timer expires or a hardware error is detected by microcode on the co-processor adapter. The LED also turns on when power is applied initially to the co-processor adapter; it turns off after a successful power-on self-test (POST).

Co-processor adapter PROM

Two 27C256 chips (200-nS access time) provide the 64KB of co-processor adapter PROM.

8030 Serial Communications Controllers (SSC)

The primary function of the four SCCs is to provide controller logic for eight independent serial communications ports.

After initial configuring of the 8030s by the Realtime Control Microcode, a major portion of the serial communications workload is relieved from the 80186 processor and is performed by the 8030s.

8036 Counter/Timer and Parallel I/O Unit (CIO)

The CIO provides peripheral I/O support through an integrated chip containing three independent 16-bit counters or timers, two independent 8-bit double-buffered I/O ports, and a special purpose 4-bit I/O port.

One timer and the 4-bit I/O port are used by the on-board watchdog timer to provide interrupt notification of a run-away CPU or a run-away operation. Two timers and two ports are used in peripheral I/O control of data through the co-processor adapter's electrical interface boards.

The Realtime Control Microcode is the on-board multitasking supervisory control program (Task 0) for the co-processor adapter. The program can be found on the Realtime Interface Co-Processor Diagnostics and Realtime Control Microcode diskette that came with your co-processor adapter.

Realtime Control Microcode (RCM)

The RCM supports the co-processor adapters through two versions. Version 1.x is named ICAAIM.COM. It provides support for the Realtime Interface Co-processor Adapter, the Multiport Adapter, and the Multiport/2 Adapter. Version 2.x is named ICARCM.COM. It provides support for the Portmaster Adapter/A and the Multiport Adapter, Model 2.

Watchdog Timer

A watchdog timer has been incorporated on the co-processor adapter card. This timer, once activated, must continually be strobed by software so that it will not time out. If the 80C186 processor ever has a fatal error, this timer will reach its terminal count. The terminal count will activate an LED indicator on the co-processor adapter card.

One timer and one 4-bit I/O port are used by the on-board watchdog timer to provide interrupt notification of a runaway CPU.

Shared Storage Interface Chip

The SSIC provides a convenient and flexible way of passing data and control bytes between the 80186 bus and the system unit bus. This is accomplished through an IBM CMOS gate array called the Shared Storage Interface Chip, an array of 10,000 gates. The chip adapts to both 8-bit and 16-bit data buses on the system unit bus. The VLSI gate array's basic purpose is to provide a high performance interface between the co-processor adapter and the system unit. All data communications between the system unit and the co-processor adapter are done through this interface. This is accomplished through the following functions performed by the Shared Storage Interface Chip.

Direct Memory Access

The co-processor adapter card has 16 DMA channels dedicated to the transmit and the receive function of each of eight ports. In addition, two DMA channels are assigned to on-card memory-to-memory transfers.

Physical Card Number
   The IBM Realtime Interface Co-processor Multiport/2 or X.25 Interface Co-processor/2 supports up to 16 different adapters in various RAM/ROM locations, utilizing 7 different interrupt levels and various clocking options.

The Physical Card Designation will be automatically configured with the following rules:

1. I/O address (Physical Card Designation) is the lowest possible interrupt level.

The I/O address defines the physical card designation of the IBM Realtime Interface Co-processor Multiport/2 or X.25 Interface Co-processor/2. This is actually a RANGE of addresses, 8 bytes wide. The preferred address range is the lowest available.

Shared Storage Window Location & Size
   The IBM Realtime Interface Co-processor Multiport/2 or X.25 /2 supports up to 16 different adapters in various RAM/ROM locations utilizing 7 different interrupt levels and various clocking options. The Memory Location will be automatically configured with the following rules:

1. Memory address is the lowest possible and the Shared Storage Window size is 8KB.

The Shared Storage Window is an unused ROM or RAM address range that is used as a window into the RAM on the IBM Realtime Interface Co-processor Multiport/2 or X.25 /2. The preferred choice is the window at the lowest address with a size of 8K. The 8K window size is compatible with the IBM Realtime Interface Co-processor and the IBM Realtime Interface Co-processor/Multiport.
