viii Equinox Megaport SS Board Series Hardware Manual
1 Overview Equinox Megaport SS Boards are intelligent, high-speed (up to 115K bps) multiport boards providing high performance serial I/ O solutions for ISA, EISA and Micro Channel bus systems. All port interfaces are standard RS-232 with modem control and voltage surge protection. Megaport SS Boards The Megaport SS Board (shown in Figure 1-1) occupies a slot in the host computer and provide the intelligent functions to "offload" the CPU serial communications processing tasks.

Megaport SS Boards Software Driver 1-2 All Megaport SS Boards include a software driver diskette and installation manual. EISA and Micro Channel machines must run their setup utility whenever a board is added or removed from the computer.
Adapter Cable Included with each Megaport 12/24 SS Board is an adapter cable. The adaptor cable is connected to the board and terminates with one or two 50-pin telco connector (illustrated in Figure 1-2). These connectors are attached to any one of a variety of splitters and distribution panels for device connection. The cable used with Model SSM-12 Megaport boards terminates with one telco connector providing port connections for up to 12 devices.

2 Installation The system requirements for ISA, EISA and Micro Channel Platforms are discussed in this chapter. Megaport SS Boards appear to the system host processor as memory. That is, they are memory mapped devices. Each board is automatically mapped into system memory at the time of device driver installation. The device driver soft-configures all boards each time the system is initialized (booted).

Select a unique I/O base address from the list in Figure 2-2 for the ISA host controller board. Assign the I/O base address by setting S1 (DIP switch shown in Figure 2-1) to the selected address. If you select an address that is invalid, simply shutdown your system and select another address. It is not necessary to reinstall the software driver after changing the I/O addresses. Address Log You may need to refer to the I/O base address assigned to the board(s) when installing the driver.
EISA System Setup The EISA Configuration Utility that came with your computer reserves system resources for each board (subsystem) that is installed. This resource information is stored in the EISA system CMOS. When your system boots, the Equinox software driver will read the assigned board information directly from the CMOS configuration. Following is a general discussion on using this system utility, you should consult your host documentation for specific procedures for your system.
Micro Channel System Setup The Micro Channel Setup Utility that came with your computer reserves system resources for each board (subsystem) that is installed. This resource information is stored in the Micro Channel system CMOS. When your system boots, the Equinox software driver will read the assigned board information directly from the Micro Channel CMOS configuration.
Installing the Adaptor Cable Equinox Wiring Accessories Connect the adaptor cable to the Megaport SS Board connector as follows: 1. Locate the 100-pin female connector on the Megaport SS Board. 2. Notice that the 100-pin cable connector is keyed such that it can only attach to the board in one orientation. With the cable properly oriented, insert the 100-pin male cable connector into the female Megaport SS Board connector and press firmly. 3.
3 Port to Device Cabling This chapter describes the options available for cabling devices to ports connected to Megaport SS Boards (see Figure 3-1). These ports provide a standard RS-232 interface with modem control signals. Figure 3-1.
Port Signal Names To assist in wiring the SSM- Megaport board, Equinox sells a complete set of cabling accessories. See an Equinox Ordering Guide for more information. The names of signals on the telco connectors of the Megaport ports indicate the direction of the signals. They are either inbound (received by the Megaport board) or outbound (transmitted from the Megaport board).
Telco Connector Pinouts SSM-8 Megaport Board Pinouts SSM-12 Megaport Board Telco Connector Pinouts This part of Chapter 3 lists the cable pinouts of the ports. The physical ports are mapped by the device driver into UNIX/XENIX tty device names. Port one is the upper most port on the back of the SSM-8. See Figure 3-9 for RS232 pinout information. Figure 3-2 shows the wiring of the telco connector on the SSM-12 Megaport Board. A single cable provides all the signals required for supporting 12 ports.
The wiring of the telco connectors on the SSM-24 Megaport Board is SSM-24 Megaport Board Telco Connector shown in Figure 3-3. Connector A provides ports 1-12 and is identical to the SSM-12 connector. Connector B provides ports 13-24. Pinouts Various accessories may be used to connect devices to Megaport SS ports. The two primary wiring methods are: DB-25 wiring and modular wiring. Figure 3-3.
Modular Wiring Modular splitters are used with modular adaptors and modular cables to connect devices to the board (see Figure 3-5). Modular adaptors and cables are used for attaching devices to the selected cabling option (see Figures 3-5 and 3-6). Figure 3-5. Modular cable wiring Punch blocks may also be used with modular wall outlets and other modular accessories (see Figure 3-6). Figure 3-6.
DB-25 Wiring DB-25 Distribution Panels Distribution panels convert 50-pin connectors to twelve DB-25 RS232 connectors (see Figure 3-4). One distribution panel or fan-out cable is required for 12 devices. Two are required for 24 ports. The following distribution panels are available from Equinox: Distribution Panel Internal Wiring Part No.
Figure 3-8. Internal wiring for DTE distribution panels Modular Wiring Modular Splitter Port to Device Cabling Modular splitters are used with modular adaptors and modular cable. Modular splitters convert the 50-pin connector to a set of 12 modular jacks. Figure 3-5 illustrates devices connected to the Megaport using the modular splitter. ● The modular splitter (Equinox part number 210016) converts the signals on the 50-pin connector to 12 RJ-11 modular jacks.
The modular splitter is wired as shown in Figure 3-9. Signal names shown refer to those present on the telco connector. Figure 3-9. Modular splitter wiring ☞ 3-8 SSM-8 ports are wired the same as shown above for ports 1 through 8.
Modular Cables RJ-11 modular cable is the flat cable used for wiring telephones inside of buildings. The cable is terminated at each end with a RJ-11 modular plug (connector). This plug is inserted into the modular jack of an appropriate wiring module. Standard modular cables, available from Equinox or wiring distributors, are reversing. That is, the pins are reversed on each end so that pin 1 on one end is connected to pin 6 on the opposite end (pin 2 is connected to pin 5, etc).
Figure 3-11. Modular adaptors ☞ 3-10 When making modular adaptors, the 3K resistor shown in Figure 3-11 may be eliminated for use with most terminals. The resistor is used to loop control signals back to the attached device when 4-wire cable is used and pin 6 is not connected. When using 6-wire cable and there is a voltage on pin 6, the resistor has no effect and the voltage on pin 6 is passed through to the attached device.
Punch Blocks Punch blocks provide a quick and inexpensive solution to wiring around buildings. They may be concealed in wiring closets and individual wires run to each location where a terminal or port is to be connected. Punch blocks may be used with modular wall outlets and wiring accessories. Figure 3-6 illustrates connecting the Megaport SS board to punch blocks using modular adaptors and modular wall outlets. Wall outlets Figure 3-12.
