Introduction
Sealevel Systems ROUTE 56 Page 1
Introduction
Overview
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.

Sealevel Systems ROUTE 56 Page 4
Installation
The ROUTE 56 can be installed in any of the 16-bit 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,
RS-530/422 and MIL-188.
•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.

Technical Description
Sealevel Systems ROUTE 56 Page 5
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 4 byte block of I/O address and a 16K block
of memory address. The memory range of this adapter can be configured to
reside in the lower 1 Megabyte of memory and appear to the system as a bank
switched 16K window or the on-board memory can be used by the system as a
256K linear address block in the upper 4 Megabytes of memory. When using
either address configuration, the ROUTE 56 adapter's memory range can be
disabled allowing multiple adapters to share the same block of memory.
Features
•Single channel high speed sync/async wide area network (WAN)
interface
•RS-232, RS-422/449, EIA-530, V.35 and X.21 serial interface
capability with versatile cabling options

protocol), Frame Relay, X.25, high-speed Async, Bisync, Mono-Sync,
HDLC, SDLC and MIL-188
•Ideal for Fractional T1, T1, E1, and ISDN applications
•On-board Z16C32 (IUSC™) with built in DMA controller and 32 byte
FIFO buffer
•Up to 10 Mbps burst mode
•256K of on-board RAM
•Link list DMA supported
•16-bit data path
•Off loads communication processing

Technical Description
Sealevel Systems ROUTE 56 Page 6
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, which can be configured, as
“low” or “high” addressing. When in low addressing mode, the 256K bytes of
SRAM appear to the host processor in the 2nd 512K bytes of the host’s
memory address range, (Segment 8000 to F000). In addition, the 256K of
SRAM appears to the host in a 16K bank-switched window. The address of the
16K window and the page is software selectable. When in high addressing
mode, the entire 256K bytes of SRAM are accessible to the host processor
simultaneously in the Linear Address Range C00000 to FFFFFF. The IUSC
always views the 256K of SRAM as linear memory. The SRAM can be
selectively disabled through software. The SRAM must be addressed in a
section that does not conflict with system DRAM.

Appendix A -Troubleshooting
A Developers Toolkit Diskette is supplied with the Sealevel Systems adapter
and will be used in the troubleshooting procedures. By using this diskette and
following these simple steps, most common problems can be eliminated
without the need to call Technical Support.
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 IRQ’s, 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 diskette and User Manual to verify that the Sealevel
Systems adapter is configured correctly. The supplied diskette 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 diskette 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:

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 (-3to -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.

Appendix C -Electrical Interface
Sealevel Systems ROUTE 56 Page 14
RS-530
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 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 refereed 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 type of interface
circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating
Equipment (DCE). The Sealevel Systems adapter is a DTE interface.
MIL-188
This communications standard comes is two varieties, MIL-188/C and
MIL-188/114. Both of these interfaces are military standards that are defined
by the US Department of Defense. MIL-188/114 is a differential interface and
MIL-188/C is a unbalanced or single ended interface. Both MIL-188 interfaces
are implemented on a RS-530 connector. MIL-188/C and MIL-188/114 have
signal levels from +6 volts to -6 volts and are ideal for long distances at high
speeds.
