Introduction Introduction Overview The ROUTE 56.PCI 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 Zilog Z16C32 (IUSC™) on chip DMA controller eliminates bus bandwidth constraints that are placed on typical 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. What’s Included The ROUTE 56.PCI is shipped with the following items. If any of these items are missing or damaged, contact the supplier. • ROUTE 56.PCI Adapter • Sealevel Software CD Sealevel Systems ROUTE 56.PCI Page 1 Installation Installation Operation System Installation Windows 95/98/ME/NT/2000/XP Do not install the Adapter in the machine until the software has been fully installed. 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5. Select the Part Number for your adapter from the listing. 6. Select ‘Windows 98/ME/2000/XP’. The setup file will automatically detect the operating environment and install the proper components. Next (depending on the OS version) select the ‘Run this program from its current location’ or ‘Open’ option. Follow the information presented on the screens that follow. 7. A screen may appear with the declaration: “The publisher cannot be determined due to the problems below: Authenticode signature not found.” Please select the ‘Yes’ button and proceed with the installation. This declaration simply means that the Operating System is not aware of the driver being loaded. It will not cause any harm to your system. 8. During setup the user may specify installation directories and other preferred configurations. This program also adds entries to the system registry that are necessary for specifying the operating parameters for each driver. An uninstall option is also included to remove all registry/INI file entries from the system. Physical Installation The adapter can be installed in any 5V PCI expansion slot and contains several jumper straps for each port that must be set for proper. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available PCI slot and remove the blank metal slot cover. 4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5. Replace the screw. (This is required to ensure FCC Part 15 compliance.) 6. Replace the cover. 7. Connect the power cord Installation is finished. The ROUTE 56.PCI 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. Sealevel Systems ROUTE 56.PCI Page 2 Installation • 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. Sealevel Systems ROUTE 56.PCI Page 3 Technical Description Technical Description The Sealevel Systems’ ROUTE 56.PCI adapter was designed for seamless integration into any PCI based system. The ROUTE 56.PCI adapter requires a PCI slot, one IRQ, an 8 byte block of I/O address and a 16K block or 256K block of memory address. The memory range of this adapter can be configured to reside in the lower 1 Megabyte memory only or anywhere in upper memory. Low memory must to be configured as 16 X 16K blocks of page memory. High memory can be configured as a 256K linear block or 16K paged memory. Features • Single channel high speed sync/async wide area network (WAN) interface • RS-232, RS-422/449, EIA-530, V.35 and RS-485 serial interface capability with versatile cabling options • Multi-protocol capable including: PPP (point-to-point protocol), Frame Relay, X.25, high-speed Async, Bi-Sync, Mono-Sync, HDLC, SDLC, etc. • Ideal for T1, Fractional T1, E1, and ISDN and other WAN 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 • OEM Security feature available as an option IUSC™ The ROUTE 56.PCI 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 IUSC’s built-in DMA controller supports 4 different modes of DMA transfer: Single Buffer, Pipelined, Array, and Link List. An on-board 20MHz oscillator clocks the IUSC. RAM The memory window is located by BIOS PCI setup or the Set PCI function. The window size is a 16K paged or 256K linear block. In paged mode the registers are located in the I/O registers. • Low Memory options: 16 pages of 16K memory blocks totaling 256K. • High Memory options: 16 pages of 16K memory blocks totaling 256K or one linear block of 256K memory.

Sealevel Systems ROUTE 56.PCI Page 11 Appendix A - Troubleshooting Appendix A - Troubleshooting The Developers Toolkit Software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting procedures. Using this software and following these simple steps can eliminate most common problems 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 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 PCI 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. 6. Windows users can use the installed programs in the SeaMAC folder to verify operation.

Authorization Can Be Obtained By Calling Sealevel Systems And Requesting A Return Merchandise Authorization (RMA) Number. Sealevel Systems ROUTE 56.PCI Page 13 Appendix C - Electrical Interface 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-485 RS-485 is backwardly compatible with RS-422; however, it is optimized for partyline or multi-drop applications. The output of the RS-422/485 driver is capable of being Active (enabled) or Tri-State (disabled). This capability allows multiple ports to be connected in a multi-drop bus and selectively polled. RS-485 allows cable lengths up to 4000 feet and data rates up to 10 Megabits per second. The signal levels for RS-485 are the same as those defined by RS-422. RS-485 has electrical characteristics that allow for 32 drivers and 32 receivers to be connected to one line. This interface is ideal for multi-drop or network environments. RS-485 tri-state driver (not dual-state) will allow the electrical presence of the driver to be removed from the line. Only one driver may be active at a time and the other driver(s) must be tri-stated. RS-485 can be cabled in two ways, two wire and four wire mode. Two wire mode does not allow for full duplex communication, and requires that data be transferred in only one direction at a time. For half-duplex operation, the two transmit pins should be connected to the two receive pins (Tx+ to Rx+ and Tx- to Rx-). Four wire mode allows full duplex data transfers. RS-485 does not define a connector pin-out or a set of modem control signals. RS-485 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. Sealevel Systems ROUTE 56.PCI Page 14 Appendix C - Electrical 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.
