Please take a few minutes to read these first few pages to prevent problems arising due to software or hardware conflicts. Also, before you have installed the software, you may want to check the Readme.txt file on the diskette labeled SrDA POP Installation Software for any last minute changes or corrections not contained in this manual. This file can be viewed using a text editor such as Notepad.exe.

It is always a good and safe idea to make a backup copy of your original software. If you have not done so, make a backup copy of your SrDA POP diskette before beginning installation. Store your original diskette in a safe place.

Before installing one or more SrDA POP adapters in available ISA slot(s), the user must first select an available IRQ interrupt number and Base I/O address. Hardware jumpers may be adjusted to reflect these selections and the adapter(s) can be installed into an available slot(s).

The user starts the installation by verifying the validity of the selected IRQ and Base I/O address and then installs the software drivers supplied on the diskette labeled SrDA POP Installation Software according to the instructions outlined in the Software Installation section of this manual. The computer is then shut down, the SrDA POP adapter(s) are installed, and the computer is rebooted.

The SrDA POP 8-line adapter requires one full length ISA Bus slot. The SrDA POP 4-line adapter requires one half-length ISA Bus slot. Careful attention must be applied to the use of ground straps and other precautions to avoid static buildup and discharge. Such discharge may permanently damage SrDA POP adapters and other electronic components. Each SrDA POP adapter must be securely fastened in the supplied ISA bus slot with a screw attached to the SrDA POP front bracket and the enclosure. Before tightening this screw, first insert a RJ45 modular plug into one or both of the SrDA POP RJ61X sockets to make sure that the connecting patch cable can be easily inserted and removed. With the RJ45 plug(s) installed, tighten the attaching screw securely.

The physical modular plug is commonly referred to as an RJ45 jack. When this physical plug is wired to contain 4 tip and ring telephone lines as required by SrDA POP specifications, then this plug is more correctly referred to as RJ61X. This wiring is defined and described in the telephone company Uniform Service Order Code (USOC) manual as RJ61X. Use this specification when telephone lines are ordered from the local telephone company to have the telephone company installer terminate the lines in the required format. Once installed, the user will connect the SrDA POP adapter(s) using RJ45 patch cords.

Windows NT Server Software requires all drivers to register hardware resource requirements with the operating system. If there is a conflict in Base I/O address settings or IRQ assignment, then the driver will not load during the boot process and a message will be posted to the System Log describing the conflict. The System Log can be viewed using the Event Viewer program. This program can be executed by clicking on the Event Viewer icon found in the Administrative Tools (Common) folder.

If a conflict is found, then the conflict must be resolved by changing jumper settings on the SrDA POP adapter or changing jumper settings on the other device or adapter which is in conflict with current SrDA POP jumper settings.

The Base I/O address selected for a SrDA POP adapter applies only to the first line. Each additional line is automatically assigned addresses, all of which have the identical Base I/O address in the least significant 10 bits of the 16 bit I/O address field. Although it is very unlikely to happen, it is possible that even if the Base I/O address selected is unique, it is possible that there may be a conflict with one or more of the automatically assigned addresses. The recommended procedure is to make sure the Base I/O address is unique, then install the adapter. If there are any conflicts, the SrDA POP driver will write messages on the System Log that can be viewed using the Event View program.

Carefully check your selected jumper settings with the resources indicated in these panels just prior to installing SrDA POP adapters in order to detect any conflicts. Hardware jumper settings are described in detail in the following section.

Also, make sure that the system CMOS BIOS allocates the selected IRQ(s) as available for Legacy ISA adapters instead of the Plug and Play pool. Check this on the next boot sequence. Reference your motherboard documentation that explains the BIOS administration procedures. Currently, there is no method of communicating this status to NT by the BIOS. Therefore, NT can accept the registration of an IRQ without knowledge that the IRQ is reserved for Plug and Play allocation.

The following drawing shows the locations of the jumpers used to select Base I/O address which is subdivided into a Card number and Address number field, IRQ SHARE and IRQ interrupt number for the SrDA POP:

There are four hardware settings that can be changed using jumpers on the SrDA POP adapter. The first two settings are the Base I/O address and the card number. The third setting is the IRQ selection, and the fourth setting is IRQ SHARE. Several SrDA POP adapters can share the same Base I/O address and IRQ selection. Changing each setting can be described as follows:

There are 8 jumpers that are used to select the Base I/O address and the card number. Refer to the Jumper Locations section for the location and label identification. Multiple SrDA POP adapters may be installed using the same Base I/O address and IRQ assignment by increasing the card number assignment by one for each adapter starting at card number zero and ending at card number seven. This allows up to 8 SrDA POP adapters to be installed using the same Base I/O address AND the same IRQ number assignment.

There are 11 possible IRQ assignments. Only one jumper can be used to select one of the following IRQs:

If more than one SrDA POP adapter is installed with the same IRQ assignment, this jumper must be selected by setting the jumper to cover the pins identified as 1 and 2. This is the default setting. Leave this jumper in its default setting in any case.

This USOC specification allows the use of patch cords that have either straight through or reversed wiring. This simplifies the construction of the patch cords by the user.

The first four SrDA POP lines are connected to the top RJ61X socket and the last four lines are connected to the bottom RJ61X socket.

The user should first record the following information prior to installing the driver:

• The Base I/O address
• The total number of SrDA POP lines to be installed. (4, 8, 12, 16, ...., 64) for each Base I/O address and IRQ selection
• The IRQ selection

The actual installation of the SrDA POP adapters can take place after the installation of the software drivers. However, if the user is very sure of the accuracy of the IRQ and Base I/O address settings, the SrDA POP adapters can be installed at any time prior to the installation of the software drivers.

After booting Windows NT Server, select the Control Panel icon in the Settings folder. This will present the following panel to the user.

Select the Network icon and receive a panel similar to the following:

• 10.0.0.0 through 10.255.255.255 (a Class A network)
• 172.16.0.0. through 172.31.255.255 (16 contiguous Class B networks)
• 192.168.0.0 through 192.168.255.255 (256 contiguous Class C networks)

Clicking OK returns the user to the Remote Access Setup panel.

Click on OK and return to the Network panel.

Now, you can shut down the computer, turn off the power and install the SrDA POP Adapter(s) with the appropriate settings. Turn on the power, and boot NT Server.

To install additional SrDA POP adapters with the same IRQ and Base I/O address, click on the Adapters tab on the Network panel, highlight the correct [x] Virtual Media SrDA POP Adapter line, and click on Properties. The Virtual Media SrDA POP Setup panel will appear. Change the Total Ports to the new combined value and click on OK. Then select Remote Access Services found in the Services tab of the Network panel click on Properties and Add.. each additional port in the Remote Access Setup panel. Close out the Network panel, shut down, install the additional adapter(s) and reboot.

To install additional SrDA POP adapters with different IRQ and Base I/O address, click on Adapters on the Network panel, and click on Add.. This will install a new [x] Virtual Media SrDA POP Adapter from the distribution diskette.

To update SrDA POP software, click on the Adapters tab on the Network panel, highlight the first [x] Virtual Media SrDA POP Adapter line, and click on Update. A dialog box will ask that the user enter the full path for the upgrade/update OEMSETUP.INF file. Then choose Continue. Usually this file resides on a distribution diskette in which case the full path is simply A:\. A dialog box will indicate the completion of a successful update with a message including new and old version numbers. Perform this operation for every other [x] Virtual Media SrDA POP Adapter that is installed unless instructed otherwise. All installed SrDA POP adapters execute from the same driver image. Multiple copies of the driver are not loaded into Windows NT if multiple adapters are installed.

When a remote user calls a SrDA POP port, the SrDA POP server will assign a Domain Name Server address that will allow the user to specify a symbolic name such as SrDAPOP3.COM to initiate browsing instead of specifying an assigned IP address such as 123.0.0.100.

When a remote user calls a SrDA POP port, the SrDA POP server will assign a Domain Name Server address that was just described above. This allows the user to address your server as SrDAPOP3.COM. Review the previous example. The reason that the Microsoft Internet Information Server panel appeared is because the initial file retrieved by the Internet browser was named default.htm. The following panels will explain why this occurred and how one can publish other information for easy retrieval. For example, you may want to instruct your users to simply input SrDAPOP3.COM/MY PRODUCT after dialing up your server. First, select the Internet Service Manager from the Microsoft Internet Service(Common) folder found under Programs. A panel similar to the will appear:

Double click on the first line of this panel (WWW). The following panel will appear:

To answer and process incoming calls, RAS Server must be started. This can be done manually or automatically whenever Windows NT is rebooted. Windows NT Server normally automatically starts RAS. One can start and stop RAS by first selecting the Services icon in the Control Panel.

Remote Access Admin can be utilized to Start or Stop the RAS server, monitor RAS on other machines in the NT Domain, and determine the status of each RAS port. Remote Access Admin can be found in the Administrative Tools (Common) folder.

This panel illustrates 8 SrDA POP Lines with an active call on LINE1. Notice that the Server operator can Disconnect User if desired. Also messages can be sent individually or to all connected entities.

Users must be given permission to log on to the RAS server. Permissions can be granted by selecting Users in the following Remote Access Admin panel and completing the following form:

SrDAlog is designed to be operating continuously. Each user may want to set up a specific window size to meet their monitoring information requirement and at the same time preserve window area for other activity. It is easy to do this by first selecting the Properties option as follows:

To set up the RAS phone book and dialing entries, select Dial-Up Networking found under the Accessories folder in the Programs folder and receive the following panel:

SrDA POP has a maximum operating speed of 33.6 Kbps in V.34+ before any data compression. The SrDA POP V90/K56 model has a maximum receive speed of 53Kbps before any data compression when communicating with a suitably equipped central site modem. SrDA POP and the SrDA POP adapter driver support the following data modem operating capabilities:

• V.90/K56flex Dual Mode
• V.34+
• V.32 bis, V.32
• V.22 bis, V.22
• Error Correction (V.42/LapM) and Compression (V.42bis).
• Power requirements are under 5 watts for an 8-line SrDA POP adapter.
• Ringer Equivalence Type A 0.2 REN.
• DTMF dial tones.
• Silence period between off hook and transmission of active signals (answer tone or DTMF) is minimum 2 seconds.

Remote modems used to communicate with SrDA POP should be set for synchronous V.42/LapM error correction. If this is not available then set the modem to asynchronous 8 bits data and no parity. Windows NT includes licensed software compression from STAC Electronics that is excellent. This compression is available in Microsoft Windows 95 as well as Windows NT Server and Workstation. Use V.42bis only when communicating with any other endpoint. All communications are performed using PPP protocols. This is supported on all major Internet Browsers such as those supplied by Microsoft, Netscape, SUN, Apple, DEC and IBM.
