Introduction

Overview:

• The ROUTE 56 is a product that requires setup and configuration.

The ROUTE 56 adapter provides the PC with a single channel high-speed multi- protocol serial interface suitable for the most popular communication protocols. This sync/async card provides an ideal solution for high-speed applications including LAN/WAN connectivity. Utilizing the Z16C32 (IUSC™) on chip DMA controller eliminates bus bandwidth constraints that are placed on typical PC interface adapters, allowing data rates to reach 10M bps in burst mode. By utilizing the Z16C32’s 32 byte FIFO buffer coupled with 256K of on board memory, higher data rates are achieved without increasing processor overhead.

Card Setup

The ROUTE 56 contains several jumper straps for each port, which must be set for proper operation.

Address Selection

The ROUTE 56 adapter occupies a total of eight consecutive I/O locations. A DIP-switch is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports. The following table shows several examples that usually do not cause a conflict:

6
238-23F| 1| 000111XXX| On| On| On| Off| Off| Off
300-307| 1| 100000XXX| Off| On| On| On| On| On
308-30F| 1| 100000XXX| Off| On| On| On| On| On
310-317| 1| 100010XXX| Off| On| On| On| Off| On
318-31F| 1| 100010XXX| Off| On| On| On| Off| On
320-327| 1| 100100XXX| Off| On| On| Off| On| On
3A0-3A7| 1| 110100XXX| Off| Off| On| Off| On| On

Address Selection Table
The following illustration shows the correlation between the DIP-switch setting and the address bits used to determine the base address. Assume 300 Hex to 307 Hex is the desired base address. 300
Hex = (1) 1 0000 0X in Binary.

DIP-Switch Illustration
Setting the switch On or Closed corresponds to a 0 in the address, while leaving it Off or Open corresponds to a 1.

Interface Selection

When IFSEL = 1, then the values read from M3-M0 are determined by values written to base+5 register. If this method is utilized, all switches on SW2 should be set in the off position, unless a default value is required. The following table shows the valid options:
The Route 56 supports a variety of electrical interfaces. These interfaces may be selected in two ways. The determining bit is found at Base+5, bit position D4, and is identified as IFSEL (InterFace SELect). Reference the Control/Status Register Descriptions, found in the Technical Description section of this manual for this bit description. When IFSEL = 0, then the values read from M3-M0 are determined by the DIP-switch SW2. If all the switches on SW2 are off, then all drivers and receivers are in a high impedance state. Only one switch should be set to the on position at a time. The following example illustrates SW-2:

When IFSEL = 1, then the values read from M3-M0 are determined by values written to base+5 register. If this method is utilized, all switches on SW2 should be set in the off position, unless a default value is required. This prevents the application of excess voltages on power-up to external receivers. The following table shows the valid options.

IRQ Selection
Header E1 is used to select the interrupt request for each the Route 56. In the example below, IRQ12 is selected. This setting must be made prior to installing the adapter. Please query your system to determine the best available IRQ to use.

Header E1 IRQ Selection

Installation

The ROUTE 56 can be installed in any of the 16-bit ISA expansion slots. The ROUTE 56 contains several jumper straps for each port, which must be set for proper operation.

1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an available slot and remove the blank metal slot cover.
4. Gently insert the ROUTE 56 into the slot. Make sure the adapter is seated properly.
5. Replace the screw.
6. Replace the cover.
7. Connect the power cord.

Installation is complete.
The ROUTE 56 has a number of cabling options available. These options include:

• CA-103 – This cable provides a high quality shielded cable with the V.35 mechanical specification met on one end and a DB-25S (female) on the other end. V.35 has a mechanical specification that is impossible to place on a PC bracket and requires this adapter cable.
• CA-104 – This cable provides a 6’ extension for use with RS-232, and RS-530.
• CA-107 – RS-530 (DB-25P) to RS-449 (DB-37P) cabling adapter. RS-530 is replacing RS-449 in Telecom applications, but there is still a very large base of installed equipment that uses the RS-449 pin-out. Both standards use RS-422 to define the electrical specifications and are interchangeable via this adapter cable.
• DSR is not available on the card as shipped but can be enabled by placing a 0-ohm resistor at R30 and removing the 0-ohm resistor at R31. This will disable the use of Ring Indicator on RS-232, V.35, and RS-530A.

Technical Description

The Sealevel Systems ROUTE 56 adapter was designed for seamless integration into any ISA based system. The ROUTE 56 adapter requires a 80286 or higher CPU, one IRQ, a 8 byte block of I/O address and a 16K block of memory address. The memory range of this adapter is configured to reside in the lower 1Megabyte of memory and appears to the system as a bank switched 16K window. The ROUTE 56 adapter’s memory range can be disabled allowing multiple adapters to share the same block of memory.

• Link list DMA supported
• 16-bit data path
• Off loads communication processing
• OEM Security Feature available

IUSC ™
The ROUTE 56 adapter is based on a single Zilog Z16C32 IUSC (Integrated Universal Serial Controller). Application and driver software access the IUSC registers through the first 256 bytes of on-board RAM. Register access to the IUSC can be disabled via I/O registers allowing the first 256 bytes of RAM to be used for buffer storage. The IUSC has a built-in DMA controller that allows high-speed data transfers directly to and from the 256K block of on-board memory. The IUSCs built-in DMA controller supports 4 different modes of DMA transfer: Single Buffer, Pipelined, Array, and Link List. An on-board 16MHz oscillator clocks the IUSC.

RAM
The ROUTE 56 has 256K of on-board SRAM. The 256K bytes of SRAM appear to the host processor in the 2nd 512K bytes of the host’s memory address range, (Segment 80000 to F0000). This 256K of SRAM is in a 16K bankswitched window. The address of the 16K window and the page is software selectable. The IUSC always views the 256K of SRAM as linear memory. The SRAM can be selectively disabled through software. The SRAM should be addressed in a section that does not conflict with system memory (i.e. I/O adapters, Video Memory, BIOS/BIOS extensions.)

Control / Status Registers Definition
The I/O register base address is selected by SWI. The address range is 200H to 3FFH. The control / status registers occupies 8 consecutive locations. The following tables provide a functional description of the bit positions.

Technical Description

I/O Signal Derivation
The Route 56 input/output signals are directly generated via the Zilog 16C32 IUSC.

Appendix A – Troubleshooting

Following these simple steps can eliminate most common problems.

1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be identified.
2. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O address.
3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e. SCSI adapters and on-board serial ports) do not. The IRQ is typically selected via an on-board header block. Refer to the section on Card Setup and the Control/Status port for help in choosing an I/O address and IRQ.
4. Make sure the Sealevel Systems adapter is securely installed in a 16-bit slot.
5. Use the supplied software and User Manual to verify that the Sealevel Systems adapter is configured correctly. The supplied software contains a diagnostic program “SSDR56” that will verify if an adapter is configured properly. This diagnostic program is written with the user in mind and is easy to use. Refer to the “README.txt” file on the supplied software for detailed instructions on using “SSDR56”.
6. The following are known I/O conflicts: • The 278 and 378 settings may conflict with your printer I/O adapter.
   • 3B0 cannot be used if a Monochrome adapter is installed.
   •  3F8-3FF is typically reserved for COM1:
   • 2F8-2FF is typically reserved for COM2:
   •  3E8-3EF is typically reserved for COM3:

Appendix C – Electrical Interface

RS-232
Quite possibly the most widely used communication standard is RS 232. This implementation has been defined and revised several times and is often referred to as RS 232 or EIA/TIA 232. It is defined by the EIA as the Interface between Data Terminal Equipment and Data Circuit- Terminating Equipment Employing Serial Binary Data Interchange. The mechanical implementation of RS 232 is on a 25 pin D sub connector. RS 232 is capable of operating at data rates up to 20 Kbps at distances less than 50 ft. The absolute maximum data rate may vary due to line conditions and cable lengths. RS 232 often operates at 38.4 Kbps over very short distances. The voltage levels defined by RS 232 range from -12 to +12 volts. RS 232 is a single ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12 volts (usually +3 to +10 volts) represents a binary 0 (space) and -12 volts ( -3 to -10 volts) denotes a binary 1 (mark). The RS-232 and the EIA/TIA-574 specification defines two type of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.

RS-422
The RS 422 specification defines the electrical characteristics of balanced voltage digital interface circuits. RS 422 is a differential interface that defines voltage levels and driver/receiver electrical specifications. On a differential interface, logic levels are defined by the difference in voltage between a pair of outputs or inputs. In contrast, a single ended interface, for example RS 232, defines the logic levels as the difference in voltage between a single signal and a common ground connection. Differential interfaces are typically more immune to noise or voltage spikes that may occur on the communication lines. Differential interfaces also have greater drive capabilities that allow for longer cable lengths. RS 422 is rated up to 10 Megabits per second and can have cabling 4000 feet long. RS 422 also defines driver and receiver electrical characteristics that will allow 1 driver and up to 32 receivers on the line at once. RS 422 signal levels range from 0 to +5 volts. RS 422 does not define a physical connector.

RS-530/530A
RS-530 (a.k.a. EIA-530) compatibility means that RS-422 signal levels are met, and the pin-out for the DB-25 connector is specified. The EIA (Electronic Industry Association) created the RS-530 specification to detail the pin-out and define a full set of modem control signals that can be used for regulating flow control and line status. The major difference between RS-530 and RS-530A lies in the modem control interface signals. In RS-530 the signals are differential, in RS-530A the signals are single ended. The RS-530 specification defines two types of interface circuits, Data Terminal Equipment (DTE) and Data Circuit Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.

V.35
V.35 is a standard defined by ITU (formerly CCITT) that specifies an electrical, mechanical, and physical interface that is used extensively by high-speed digital carriers such as AT&T Dataphone Digital Service (DDS). ITU V.35 is an international standard that is often referred to as Data Transmission at 48 Kbps using 60 – 108 KHz Group-Band Circuits. ITU V.35 electrical characteristics are a combination of unbalanced voltage and balanced current mode signals. Data and clock signals are balanced current mode circuits. These circuits typically have voltage levels from 0.5 Volts to -0.5 Volts (1 Volt differential). The modem control signals are unbalanced signals and are compatible with RS-232. The physical connector is a 34 pin connector that supports 24 data, clock, and control signals. The physical connector is defined in the ISO-2593 standard. ITU V.35 specification defines two types of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.
