Software and Hardware Installation

Installation Overview

Installation is 3 part process where you will 1) install the Keyspan software, 2) connect your adapter, and 3) determine your adapter's COM port assignment. This last step is important because this is

COM port that you will tell your serial device to use. Please follow the instructions below to complete this process

Install Keyspan Software

Important Notes:

DISCONNECT your Keyspan adapter BEFORE install the Keyspan software.

1. Install the Keyspan Software:

CDROM Installation:

Windows will automatically open the Keyspan CD Browser window (Note: you can manually start the CD browser by locating and running the "Launch.exe" program on the CD-ROM). Using the onscreen menus, locate the Keyspan Installer selection and click it to start the installation process.

Follow the instructions on-screen.

Installation via download:

Download the Keyspan driver from Keyspan's website (http://www.keyspan.com). Find and download the Keyspan USA-19HS installer. When you have downloaded the installer, run installer.

WINDOWS Vista Tech Note:

During and/or after the software installation, Windows may report ''Windows can't verify the publisher of this software'', click the ''Install this driver software anyway'' selection.

2. Follow the installer's onscreen instructions to finish the software installation. When the installer completes, proceed to the Step 3 (Setup Hardware).

Setup and Connect the Keyspan Hardware

3. Connect one end of the USB cable to the USB port on the back of the Keyspan adapter. Connect the other end of the USB cable to the USB port on your computer. When you connect the adapter,

Windows will detect your Keyspan adapter. During this time, you may see Windows messages appear and disappear showing the names of different components of the Keyspan adapter. This is normal during the the first installation of your adapter.

WINDOWS Tech Note:

During and/or after the hardware installation, the Windows New Hardware Wizard may ask you to install software several times. Select ‘Install the software automatically’. You may also get an additional prompt regarding logo testing, click ‘Continue Anyway' if it appears. Note that you may get this message several times. Continue through all the Hardware Wizards that appear until they stop appearing (you may see up to 3 Hardware Wizards).

4. When Windows has finished the installation of drivers for your adapter, proceed to the Step 5 (De-

termine Keyspan's COM Port Assignment).

USA-19HS - User Manual (rev 3/11/08) Page 3 of 34

Determine Keyspan's COM Port Assignment

5. We now need to determine which COM port was assigned to the Keyspan adapter. The adapter's

COM port is important because you will be telling your serial devices (ie modem, PDAs, GPS, etc) to use the Keyspan COM port. You can determine Keyspan's COM port assignment by using the

Keyspan Serial Assistant utility. Open Keyspan Serial Assistant utility (START menu > (All) Pro-

grams > Keyspan > Keyspan Serial Assistant). You will be presented with the following window:

Keyspan Serial Assistant window

6. In the Keyspan Serial Assistant window, you will see your adapter's COM port assignment. You should see COMxxx : IDLE or COMxxx: BUSY.

Note the COM port address (ie COM1, COM2, etc) as you will need this information later.

IDLE message:

If you see the IDLE status message, the Keyspan adapter is working and waiting for some program to access the Keyspan COM port. This is the normal state of the adapter. If you look at your adapter's status light, it will be blinking slowly (1 blink per sec.) to indicate that it is idle.

Proceed to the Making Your Keyspan Adapter Work With Your Serial Device section.

BUSY message:

If you see the BUSY status message, the Keyspan adapter is working and some program has already gained access the Keyspan COM port. If you look at your adapter's status light, it will be on

(not blinking) or blinking every time data is sent or received (this can be a rapid blink or a blink every couple of seconds). Assuming that your serial device's software gained accessed to the

Keyspan adapter, you should be able to start using your serial device right away. In some cases, it may be another program that is accessing the COM port before your serial device has had a chance to get to the COM port. In these cases, please read the Troubleshooting section in this manual for further assistance.

No Keyspan Adapters Detected message:

If you see the No Keyspan Adapters Detected status message, there is a problem with the installation. Please read the Troubleshooting section in this manual for further assistance.

If you see either the IDLE or BUSY message, proceed to the Using Your Keyspan Serial Port section later in this manual.

USA-19HS - User Manual (rev 3/11/08) Page 4 of 34

Using The Keyspan Serial Port

Overview Of Using Serial Devices with Serial Ports

Using a serial device with any serial port requires:

• [hardware] serial device (ie a modem, glucose meter, GPS, etc).

• [software] software that sends/receives data from your serial device (ie your GPS software).

• [hardware] a serial port (provided by your Keyspan adapter).

• [software] a COM port provided by the Keyspan software.

• [setup] your serial device's software needs to be told to use the Keyspan COM port.

This chapter will show you how to use the Keyspan adapter hardware and software. It will also provide an overview of how to setup your serial device.

Note:

Please note that this chapter assumes that you have completed the steps outlined in the Software

and Hardware Installation section earlier in this manual.

Connecting and Configuring A Serial Device To Use A Keyspan Adapter

The basic outline to connecting and configuring your serial device to use the Keyspan are:

1. Connect your Keyspan adapter to your computer's USB port.

2. Connect your serial device to the Keyspan adapter.

3. Determine the Keyspan COM port via the Keyspan Serial Assistant

4. Open your serial device's software and tell that software to use the Keyspan COM port

5. Tell you serial device's software to 'communicate' with the serial device (ie start using the serial device like you would normally.

For example, if your Keyspan adapter is assigned to COM6, you need to tell your serial device's software to use COM6. The serial device's software is the program that you run to send/receive data from your serial device. This is where you need tell that program to use the Keyspan COM port.

Please refer to your software's instruction manual for information on how to select a COM port. If you do not have this information, feel free to contact Keyspan support as we may have this information documented.

Important Note:

If you find your program's COM port selection screen and find that it does not allow you to select the

Keyspan COM port because its port selection screen is limited (ie your software only shows COM1 through COM4 but your adapter is on COM8), you will need to change the Keyspan COM port address.

Please read the Changing Your COM Port Address section later in this manual.

Once you have installed the Keyspan software and connected the Keyspan adapter [hardware] to your computer, you are ready to connect your serial device hardware to the Keyspan adapter's DB9 port.

1. Connect your serial device's cable to the Keyspan adapter's DB9 port.

USA-19HS - User Manual (rev 3/11/08) Page 5 of 34

DB9 port on USA-19HS

Note:

If your serial device has a different connector, you may need a converter cable or adapter to connect your device to a DB9 port. Please contact the manufacturer of your serial device for details.

Now that you have physically connected your serial device to the Keyspan adapter, we need to connect your serial device's software to the Keyspan COM port (software). Before we can do this, we need to determine the Keyspan COM port. If you already know the Keyspan COM port, skip Step 2.

2. Open Keyspan Serial Assistant utility (START menu > (All) Programs > Keyspan > Keyspan Serial Assistant). You will be presented with the following window:

Keyspan Serial Assistant window

Alternate Method:

You can also use the DEVICE MANAGER in Windows to determine the Keyspan COM port. COM ports are shown in the Device Manager under the PORTS (COM & LPT) section.

Write down the COM port shown in the ADAPTER STATUS tab. We will need this in the next step. You can close the Keyspan Serial Assistant when you have noted your COM port.

Note:

COM ports are assigned on the basis of what COM ports (software addresses) are available on your computer. Because of this, your adapter may be assigned to COM3 on one computer and the same adapter will be assigned to COM9 on another computer.

COM port addresses can be reserved by software. Microsoft typically reserves COM1 and COM2 on most Windows 2000, XP, and Vista computers. Devices such as internal modems, Bluetooth devices, and other USB to serial adapters will also reserve COM ports. This topic is discussed in more detail in the Changing Your COM Port Address section later in this manual.

USA-19HS - User Manual (rev 3/11/08) Page 6 of 34

3. Open your serial device's software. This is the software that you would normally use to communicate with your serial device. We need to tell this software to use the Keyspan COM port (from

Step 2). Normally, this is found in a COM port selection screen, menu, etc. Please see your serial

device's manual for instructions on how to select a serial port. Once you find this screen, proceed to the next step.

Note:

Every serial device COM port selection screen is different. Some serial device's have COM port selections in a control panel, some have their COM port selection screens in menu's called Settings, Communication, Preferences, etc, and others may not have a place to select a serial port. If you do not know how to access your serial device's COM port selection screen and you cannot get support from your serial device's manufacturer, please note that Keyspan FAQ pages have instructions on how to access and configure many popular serial device's and software. You can access our FAQs via our support web page at http://www.keyspan.com/support/

4. In your serial device's COM port selection screen, select the Keyspan COM port (the one that you noted in Step 2).

Note:

If your software shows a limited number of ports and your Keyspan COM port is not in that range, you will need to either get updated software that can see all COM ports or you will need to change the

Keyspan COM port to one that your program can use.

If you need to change your Keyspan COM port, see the Changing Your COM Port Address section later in this manual. When you have completed that section, return to this section

5. Now that you have selected the Keyspan COM port, start using your serial device like you would normally.

If your serial device is working, congratulations.

If your serial device doesn't work, please read the Troubleshooting section in this manual for further assistance.

Changing Your COM Port Address

Overview

In some cases, you will find that your serial device's software does not look for all COM ports on your system. For example, some programs will only look for COM1 through COM4. If your Keyspan COM port is above your software's range, your software will not be able to see your serial device. In this case, you have two options:

• upgrade your software to a version that can see all COM ports (recommended)

• change the Keyspan COM port address.

Keyspan recommends that you at least try to get the latest version of your serial device's software before attempting to change the Keyspan COM port since most developers have upgraded their software to be compliant with latest Windows serial communication APIs.

Developer Note:

If you are developer and want to make your software find all serial ports, Keyspan has sample code that can be used for finding all COM ports (whether they are Keyspan COM ports or not). This information can be found in the developers section on Keyspan's downloads page.

If you cannot get newer software for your serial device, your only option is to change the Keyspan

COM port. This guide will show you how to change the Keyspan COM port via the Keyspan Serial Assistant as well provide some details about COM ports in general.

How does the Keyspan adapter determine its COM port number?

Keyspan serial adapters create COM ports in the Windows registry just like the COM ports found on older computers.

When you first connect a Keyspan adapter, the Keyspan adapter software reads the Windows registry to find an 'available' COM port number.

If COM1 is not available it tries COM2, COM3, etc., until it finds a COM port number that is available.

If your Keyspan adapter creates COM4, then COM1 though COM3 are 'busy' or have been 'reserved' for some piece of hardware or software (ie an internal modem, wireless connectivity, etc).

In modern computers (ie post Windows 2000), Microsoft reserves COM1 and COM2. Other things that reserve COM ports are things like internal modems, internal/external Bluetooth (which usually resever eight COM ports), and other USB to serial adapters.

Notes:

Since every computer is different, you may find that your Keyspan adapter is COM3 on one computer and COM10 on another computer. To determine your Keyspan adapter's COM port assignment, please use the Keyspan Serial Assistant.

Change COM Port via Keyspan Serial Assistant

Note: This is an advanced feature that requires you to have Administrator privileges on your system.

1. Open Keyspan Serial Assistant utility (START menu > (All) Programs > Keyspan > Keyspan Serial Assistant). You will be presented with the following window:

USA-19HS - User Manual (rev 3/11/08) Page 9 of 34

Keyspan Serial Assistant window

This will show your Keyspan adapter and the current COM port number (ie COM4, COM 5, etc.).

2. Click 'Port Mapping' tab. Once you are in the 'Port Mapping' section select or highlight the Keyspan

COM port that you wish to change.

Port Mapping tab with Keyspan Port highlighted

With your Keyspan COM port highlighted, select the new COM port number from the 'COM Port map-

ping for the selected adapter port' pull down menu.

USA-19HS - User Manual (rev 3/11/08)

COM Port Mapping pull down menu

Page 10 of 34

Once you have selected the new COM port number, the Keyspan software will ask you if you are sure you want to proceed.

IMPORTANT:

Please note that you can select any COM port you wish however, you may notice that certain ports are 'in use'. This may mean that there is hardware connected to these COM ports or they have been reserved for the operating system or other software. Changing the COM port mapping to a COM port that is 'in use' may render any hardware and/or software using that port inoperable.

3. Your COM port has now been changed to the new COM port number. To confirm the change, click the Keyspan Serial Assistant's Adapter Status tab to see the new COM port. The COM port change is complete.

Change COM Port via the Windows Device Manager

On Windows XP and Vista, you can change your Keyspan adapter's COM port number via the Device

Manager. This requires the latest version of the Keyspan software (version 3.7 or later).

This process accomplishes the same task as changing the COM port via the Keyspan Serial Assistant however certain users may prefer to use the Device Manager to change ports.

Note: This is an advanced feature that requires you to have Administrator privileges on your system.

1. Open Device Manager by double-clicking the System control panel. Next, click the Hardware tab and then click the Device Manager button. This will open the Device Manager.

Troubleshooting

This troubleshooting guide will guide you in solving problems with the Keyspan USA-19HS hardware and software installation.

Before you begin, make sure that you have:

• installed the latest USA-19HS software (available from our website)

• your USA-19HS adapter is connected to your USB port

Note:

If you are downloading software from Keyspan's website, make sure you download the USA-19HS drivers. Keyspan has drivers for other adapters such as the USA-19, USA-19Qi, USA-19QW, etc. These drivers are not compatible with the USA-19HS.

1. Open Keyspan Serial Assistant utility (START menu > (All) Programs > Keyspan > Keyspan Serial Assistant). You will be presented with a window that looks like the following:

Keyspan Serial Assistant window

<Option 1>

The Keyspan Serial Assistant will show your adapter's COM port and status (ie COMxx:Idle or COMxx busy).

The IDLE message means that your serial device's software is not currently accessing the Keyspan port).

The BUSY message means that a program (software) has accessed the Keyspan COM port. In most cases, this means that you are ready to start using your serial device via the Keyspan adapter. If you are not able to use your serial device, contact Keyspan tech support.

If your COM port appears, the Keyspan software and hardware is installed correctly. You do not need to read the rest of this troubleshooting guide. If you are having problems, please contact Keyspan tech support for further instructions. They will need to know your COM port number and it's status

(IDLE or BUSY).

'

<Option 2>

If the message 'NO KEYSPAN USB SERIAL ADAPTERS FOUND' appears, proceed to Step 2.

2. Look at your Keyspan adapter hardware. On the front of the adapter, it will have the work

Keyspan printed on it. On the back of the adapter, find the printed p/n number (located under

USA-19HS - User Manual (rev 3/11/08) Page 14 of 34

the FCC and CE symbols).

<Option 1>

If your printed p/n number DOES NOT show USA-19HS, you do not have a USA-19HS. Refer to the correct documentation for your adapter.

Option section in the Properties tab). The test that is performed is the selected test in the Test Option box.

Note:

The baud rate shown here is only used to configure the Serial Test. If your serial device's software does not provide the necessary port settings to our adapter and you need to specify the default port settings (ie baud [bits per second], data bits, parity, stop bits, and flow control), you set these settings in the Device Manager (right-click your Keyspan COM port in the Ports (COM & LPT) heading and then select Properties and then click the Port Settings tab).

Test This Port button

The Test This Port button tests the COM port selected in the Port pull down menu (in the Serial Port

Option section in the Properties tab). The test that is performed is the selected test in the Test

Option box.

Test Mode box

The Test Mode box allows to specify the type of test that will be performed when you press the

Test This Port button. There are 3 types of tests:

TX Only:

Use this test to test only the transmit (Tx) signals of the Keyspan adapter.

Ext. LoopBack:

Use this test sending and receiving data. This test sends data out the selected serial port and waits to receive it via a special Loopback connector. You can find more information about this special Loopback connector in the Serial Port Pin Outs section in this manual. IMPORTANT!

This test will fail if you did not make and connect a custom Loopback connector.

Int. Loop Back:

Use this test sending and receiving data. This test is performed within the Keyspan adapter hardware. This test DOES NOT require a special Loopback cable.

Test Type box

The Test Type box allows to specify how many times the selected test will be repeated when you press the Test button. Use the Quick option to perform the test once. To perform a subsequent test, press the Test This Port button. Use the Continuous option to repeat the test continuously. To

USA-19HS - User Manual (rev 3/11/08) Page 19 of 34

stop the test, press the Stop Test button (the Test This Port button becomes the Stop Test button during a test).

Test Speed pull down menu

The Test Speed pull down menu allows to specify the speed (baud rate) at which the port will be tested at when you press the Test This Port button button.

Test Status box

The Test Status box reports the test status or results of the selected COM port.

Port Mapping tab

The Port Mapping tab in the Keyspan Serial Assistant allows you to change how COM port numbers are assigned to your Keyspan adapter. The following is an explanation of the items in this tab.

Important!!! Changing COM port assignments may render other hardware unusable. For step by step instructions on how to change a COM port address, read the Changing Your COM Port Address section earlier in this manual. Please make sure you read the sections about changing COM ports carefully.

COM port mapping pull down menu

The COM port mapping pull down menu allows you to reassign the selected Keyspan COM port in the

COM port list window. This window also reports whether a COM port is 'in use'. In this menu, 'in use' means that the selected COM port has assigned or reserved. It is highly recommended that you only change the COM port mapping to COM ports that are not 'in use'.

Note: The COM port mapping pull down menu allows you to change the COM port mapping to any

COM port including those that have already been assigned (aka in use). Changing the COM port mapping to a COM port that is in use may render any hardware and/or software using that port inoperable.

Adapter Port Mapping Mode box

The Adapter Port Mapping Mode box allows you to change the behavior of how Keyspan COM port numbers are assigned when you connect the Keyspan adapter to a different USB port than the one it was originally connected to.

Dynamic:

Dynamic assigns a COM port number (or numbers if your Keyspan adapter has multiple serial ports) to a particular Keyspan adapter. If you disconnect the Keyspan adapter and connect it to a different USB port, the COM port number of that Keyspan adapter will not change. This is the default setting and is recommended setting if you only have one Keyspan adapter.

Geographic:

Geographic assigns a COM port number (or numbers if your Keyspan adapter has multiple serial ports) to a particular USB port on your computer. If you disconnect the Keyspan adapter and connect it to a different USB port, the COM port number of that Keyspan adapter will change.

This setting is recommended if you are using multiple Keyspan adapters and want the COM port numbers to remain the same.

Delete All Keyspan USB Serial Adapter Port Mappings button

The Delete All Keyspan USB Serial Adapter Port Mappings button clears the Windows registry of all

Keyspan USB Serial Adapter COM port numbers and Keyspan USB information. This allows Windows to create new COM port assignments.

Note: that this is an option for advanced users only. If you are unsure about how this command will affect your computer, please contact Keyspan Tech Support for further assistance.

TX Ack Advance Details

USA-19H Tx Ack Advance Overview

Many Keyspan USB serial adapters support configurable "Transmit Acknowledgment Advance" (aka TX-

ACK threshold, aka TX-ACK(nowledgement) advance, etc.) in the Keyspan Manager. This feature allows the user to adjust a device's transmit behavior to achieve the optimum compromise between compatibility (exact emulation of built-in ports) and improved throughput. This document describes the factors which a user should be aware of to guide their configuration of this feature.

The Problem

In the case of a standard, "built-in" serial port, the host CPU (the "brain" of the computer) can communicate directly with the serial hardware because the (serial) hardware is in the address space directly accessible to the CPU. When the serial port has transmitted all the data in its transmit FIFO

(the buffer that holds characters waiting to be sent), it interrupts the CPU, which then adds more characters to the transmit FIFO with a minimal time delay.

By contrast, in a USB to serial adapter, information about the state of the serial port FIFO reaches the CPU by means of USB messages. The USB subsystem in most computers delays the delivery of inbound (USB peripheral to USB host computer) USB messages by about 1 millisecond. The impact of this delay on serial throughput depends on the baud rate. At 9600 baud, it takes about 1 millisecond to transmit a character. If the serial adapter signals the host when it begins transmitting the last character in its FIFO, the host learns about it at about the same time the character is actually finished being transmitted. Since outbound (USB host computer to USB peripheral) USB messages are not subject to such a long delay, the host can supply new data before the serial port has been idle for too long.

At higher baud rates, however, this 1-millisecond delay becomes more of a problem. For example, at

920 Kbps, 1 millisecond is enough time to send 92 characters. So, if you're sending 92 characters at a time, you will only achieve 50% throughput, since half the time is spent with the adapter waiting for the host to send more data.

The Work Around

Since there's no way to eliminate the USB delays, there's only one work around: the serial adapter has to lie about when it's done transmitting. This way, the adapter still has some data to transmit while it's waiting for more to arrive from the host. If the next data from the host arrives before the previous data is completely sent, the new data can be sent with no delay, and the device will achieve improved transmit throughput.

Notes about the Work Around

In most situations, the serial adapter's lie is harmless or beneficial, even. However, in some circumstances, this lie gets us into trouble. There are several ways this can happen:

Flow control:

If the adapter is programmed to use flow control, the remote (receiving) end of the serial connection can ask the adapter to suspend its data transmission (e.g. if it's not ready to receive more data).

Since this state can persist indefinitely, the "I'm done" indication, if it were sent early, could arrive at the host a significant amount ahead of time. As a result, the application might use the "I'm done" signal as an indication that the remote end is ready, leading to various kinds of trouble.

Data flushing:

Sometimes, an application will issue a "transmit flush" command to the adapter get rid of extra data.

For example, let's say that an application sends "AAAA" to the adapter, and then, once it's received the "I'm done" indication, sends "BBBB." Now, let's say that some time after sending "BBBB," the appli-

USA-19HS - User Manual (rev 3/11/08) Page 23 of 34

cation decides to cancel whatever part of the "BBBB" has yet to leave the serial port, and sends a

"transmit flush" command to the adapter. If the adapter had been lying about being done sending

"AAAA," it might still not be done, and the flush could purge the transmit FIFO of some of the A's

(which is not what the application was expecting) in addition to the B's.

Timing:

In some applications, the receipt of the "I'm done" indication is used as a timing reference point. For example, an application could send a data stream like this:

COMMAND................................................................

The extra periods following COMMAND would be just used to establish a timing interval: the application would know that once the serial port said "I'm done," the receiver would have had at least 64 character times to process COMMAND. If the "I'm done" indication was sent early, the application might then do its subsequent action too early.

There are many other communication protocols in which time periods are counted from the point that a message has been delivered. Any time you change the timing of the "I'm done" indication, you run the risk of interfering with such protocols.

What Should I Use?

There are two ways you can configure Tx Ack Advance:

Standard:

If you're using a baud rate of 57600 or less, you probably don't have a problem. The 1 millisecond delay will not significantly affect your throughput, and you can select this option. This option is also a good choice if you are running an application in which throughput is not an issue, or one in which guaranteeing 100% correct operation is important enough that you'd prefer not to risk having problems.

Faster:

If you're using a baud rate above 57600, you can simply try increasing this setting, and see whether it improves performance (in which case, great!), causes problems (in which case, don't use it), or doesn't make any difference (in which case it doesn't matter what you do).

Driver Events / Data Monitor Features

Overview

The Keyspan Serial Assistant's Driver Events and Data Monitor windows provide information as to what serial data is being sent/received by the Keyspan adapter (the Data Monitor utility) and what Keyspan specific actions the Keyspan adapter is using (the Driver Events utility).

Both of these features are designed for Keyspan's use in troubleshooting complex issues with serial communication. If you are having problems with a serial device, Keyspan tech support may ask you to use one or both of these features.
