Product FAQs
- Apple LaserWriter 4/600 or Laserwriter 4/600 PS Compatibility
- The Apple Laserwriter 4/600 is an Apple Laser printer. This printer shipped with Localtalk, Ethernet, and Parallel Ports. Keyspan does not have any products that would connect this printer to Mac that does not have a built in serial ports. Although Keyspan does sell a USB to Serial adapter, serial ports are not the same thing as a LocalTalk port. Because of this technical difference, Keyspan USB to Serial adapters will not work with this printer. Keyspan does sell a USB to Parallel product (http://www.keyspan.com/products/usb/up6c/) that may work with this printer under Mac OS X however this requires you to obtain a driver (from Apple or a 3rd party) that would compatible with: a) your Laserwriter 4/600, b) Mac OS X, and most importantly, c) a USB to Parallel cable. This configuration is not supported. This printer can be connected via Ethernet by using a 'Ethernet Transceiver' (AAUI to RJ-45). Once you connect the Laserwriter 16/600 via Ethernet, you can print from both Mac OS X and Mac OS 9 computers. For more information, read your printer's manual for more information.

- Difference Between USA-28, USA-28X (A/B), USA-28X
- As of December 2006, the USA-28XG is the current shipping Keyspan USB Two Port Din8 Adapter for Mac. The USA-28XG is a 'green' RoHS compliant version of the USA-28X. The USA-28XG is identical in features as the USA-28X. Over the years, there have been various models of the 'USA-28' family. The following is a list of these adapters of these adapters (with newer adapters at the top of the list): USA-28XG USA-28X (includes USA-28X, USA-28 A, and USA-28X B) USA-28 The USA-28X models (USA-28X, USA-28X A, USA-28B) were all identical to each other. The USA-28XG and USA-28X (any version) are identical to each other The USA-28 was Keyspan's first adapter. It lacked the 'external clock' support of the USA-28X/28XG models. This feature only affected serial devices that required external clock signals (ie certain Apple StyleWriters). If you have any questions or comments about this FAQ, please contact Keyspan technical support.
- Do the Keyspan serial port products support Mac OS 10.6 (Snow Leopard)?
- The latest driver version 2.6b (file: Model USA-19HS, USA-49WG, USA-28XG & UPR-112G Keyspan Driver - Mac OS 10.6 (Snow Leopard) - found in Help & Downloads section of each product as well as the download section) will allow the following products to run on Mac OS10.6. Those products are the USA-19HS, USA-49WG, USA-28XG, and the serial port of the UPR-112G. Although previous versions of these serial based products should work with the new driver release, our support staff will only be able to troubleshoot issues with the current skus. We have done extensive testing, but welcome you the user to give any additional feedback to help with the improvement of the this beta driver.
- Do you have Windows drivers for your Din-8 serial port products?
- Keyspan does not provide Windows drivers for our Din-8 serial port products (ie USA-28X, USA-28, USA-18X, SXPro4, SX2, SX4) as Windows never utilized the Din-8 serial port (Windows uses DB9 serial ports). Keyspan Din-8 serial products are made for Mac only. On top of this, Windows programs expect to speak to either DB9/DB25 serial ports which are intrinsically different from Din-8 ports. Because of this, even if you had a Windows driver for a Keyspan Din-8 product, you (as the user of this product) would need to manufacture a specific Din-8 to DB9/DB25 for your specific device (unfortunately, a universal Din-8 to DB9/DB25 is not possible due to technical issues). KEYSPAN DOES NOT PLAN ON RELEASING A WINDOWS DRIVER FOR ANY KEYSPAN DIN-8 PRODUCT DUE TO THESE ISSUES. If you need to add a serial port to a Windows computer, please note that Keyspan does provide DB9 serial ports for Windows (and Mac) in the following products: * USA-19HS (http://www.keyspan.com/products/usb/usa19hs/) and *USA-49W (http://www.keyspan.com/products/usb/usa49w/ ADDITIONAL INFO: Keyspan has never developed a Windows driver for Keyspan Din-8 products. Unfortunately, there are no beta/alpha/prerelease Windows drivers for Keyspan Din-8 products.

- The Installer package 'xxx' cannot be opened. The Bill of Materials for this package was not found.
- The message 'The Installer package 'xxx' cannot be opened. The Bill of Materials for this package was not found.' means that installer.app is having problems with the .pkg installer that you have downloaded. This means that that your .pkg file is corrupted. In general, there are two causes of this problem. The original pkg file was corrupted before you received it or the pkg file was corrupted as it was extracted/expanded after it was downloaded. Since Keyspan's downloads are tested before they are posted, the usual cause of this problem (here at Keyspan) is that your file expander (ie Stuffit or Stuffit Expander) is corrupting the file. To fix this issue, we recommend that you: 1. delete all of downloaded Keyspan files (pkg files and zip files) 2. re-download the Keyspan file(s). This time, don't use Stuffit/Stuffit Expander. Instead, find the Keyspan .zip file, select the file (aka highlight it), right click or control-click on the zip file (to open the contextual submenu), select OPEN WITH > BOMArchive Helper. This will open the file with Apple's utility and create a new .pkg file. 3. run/double-click the new pkg file. If you have any questions, please contact Keyspan support. FYI... Upgrading to the latest version of Stuffit and/or Stuffit Expander can sometimes fix this issue as well.
- Troubleshooting: Palm on Mac OS X Using Keyspan Serial Ports
- Step 1: Check The Keyspan Serial Assistant / Connect The Keyspan Adapter - - - - - If you have not installed the Keyspan software, please install it before proceeding. Once the Keyspan software is installed, connect the Keyspan adapter to your computer's USB port. Since we are troubleshooting, connect the Keyspan adapter directly into a USB port on your computer and not a USB port on a USB hub, keyboard, or monitor (you can connect the Keyspan adapter later to the desired port - connecting the adapter to a built in USB port eliminates problems introduced by USB ports on USB hub, keyboards, and mice). Now that the Keyspan adapter is connected to a built in USB port, open the KEYSPAN SERIAL ASSISTANT application. This application is found in your APPLICATIONS folder in Mac OS X. Once the KEYSPAN SERIAL ASSISTANT is open, you should be able to see your Keyspan adapter listed in the Keyspan Serial Assistant window. [Step 1: Option A: SUCCESS: Adapter Shows Up In Keyspan Serial Assistant Window] If your adapter shows up in the Keyspan Serial Assistant window, click the triangle on the LEFT of your adapter's name. This will show the name of the port that was created by your adapter (ie USAxxxyyy.p1). Please take note of this port name as we will need this in Step 3. Once you have noted the port name, close the Keyspan Serial Assistant and proceed to Step 2. [Step 1: Option A: FAILURE :Adapter DOES NOT SHOW UP In Keyspan Serial Assistant Window] If your adapter does not show up in the Keyspan Serial Assistant window, please inform Keyspan tech support of this and let us know which specific Keyspan product (name and part number) you are using. We will be able to assist you from this point on. Step 2: Open the Palm Desktop Software For Mac OS X - - - - - Open the Palm Desktop Software for Mac OS X. If you do not know how to do this or what this means, contact Palm tech support or read the Palm Mac OS X documentation. Once you have opened the Palm Desktop application proceed to Step 3. Step 3: Access The HotSync Manager And Select the Keyspan Port (from Step 1) - - - - - In the Palm Desktop Software, open the HotSync menu (located in the menu bar) and select SETUP. This will open a window with two tabs. Click the HOTSYNC CONTROL tab (the left tab). In the HOTSYNC CONTROL tab, set HOTSYNC to DISABLED (this needs to be done anytime you make a change to the HotSync options on your computer). Next, click the CONNECTION SETTINGS tab. In the CONNECTION SETTINGS tab, you should see a list of connection types with check boxes to the left the connection names. Once the connections/ports will be your Keyspan adapter. Turn ON the Keyspan connection and turn OFF all of the other (including USB). IMPORTANT!!! Match the port shown in the CONNECTION SETTINGS tab to the port name from Step 1. The names MUST match. Once you have verified this, click the HOTSYNC CONTROL tab. In the HOTSYNC CONTROL, set the HOTSYNC to ENABLED. You have now told the Palm software to use the Keyspan serial port. If you have an adapter with an embedded light, you should notice that the light is solid and not blinking slowly. Proceed to Step 4. Step 4: Try To HotSync - - - - - You should now try to HotSync. [Step 4: Option A: SUCCESS: HOTSYNC Works] If HotSync works, you are finished. If are are moving your adapter to a different USB port, please note that you will need to repeat steps 1-3. [Step 4: Option B: PARTIAL SUCCESS: HotSync Starts But I'm Asked To Create A User] If the HotSync start but you are asked to create a user account, this means that the serial connection has completed but the HotSync needs to create a 'user account' on your computer before proceeding. This is normal and part of the PALM HotSync process when you first HotSync your Palm device to a new computer. If you need help, contact Palm or read the Palm documentation on what to do next. [Step 4: Option C: PARTIAL SUCCESS: HotSync Starts But Gets Stuck On ESTABLISHING CONNECTION] If the HotSync starts but your computer screen and Palm device get stuck on ESTABLISHING CONNECTION, this means that the serial connect has completed but the Palm software is trying to match find a Palm 'User' file on your computer to HotSync with. Since it cannot find the correct file, it get stuck. This is usually caused by bad installation of the Palm software or by having multiple copies of the Palm Desktop Software (and therefore multiple Palm 'User' files) on your computer. For help with this matter, contact Palm tech support for help with cleaning up this issue. [Step 4: Option D: FAILURE: Nothing Happens] If nothing happens when you try to HotSync, repeat this process a second time. If it still fails, contact Keyspan tech support. [Step 4: Option E: FAILURE: Something else] If something else happens when you try to HotSync, please let Keyspan tech support what happens when you try to HotSync and we will direct you from there.
- What baud rates are supported by Keyspan serial ports?
- Although each Keyspan adapter is different, most Keyspan adapters support standard baud rates up to 230 Kbps. Since each adapter is different, please refer to your adapter's documentation and/or packaging about its maximum baud rate. Standard baud rates are set by your computer's OS (while maximum baud rate is usually set bu the serial port). Standard baud rates include: 110 300 600 1200 2400 4800 9600 14400 19200 28800 38400 57600 115200 230400
- What is the KeySerial1 port in Mac OS X?
- The KeySerial1 port is a feature that was added to latest version of the Keyspan Serial Adapter software for Mac OS X. The KeySerial1 port is an alias or shortcut to the: - the port 1 on a Keyspan adapter (if you have a multiple port Keyspan adapter) - of the first Keyspan adapter (any model) detected by your computer The purpose of the KeySerial1 port is to make it easier for customers and developers to easily identify and select a Keyspan port in Mac OS X based software. Keyspan still Keyspan still maintains its geographical port naming scheme. Because of this, you will get a dynamic port name and one extra port name called KeySerial1. Geographical port names will change depending on which USB port your Keyspan adapter is connected to. For example, if you have a port name called: USA19H4b13P1 This tells us that you have a USA-19HS unit that is connected to the USB location called '4b13'. If you move that adapter to another USB port, the USB location will change and you will get a different USB location and, by extension, a different port name (ie USA19H4b14P1). If your software is pointing to USA19H4b13P1 and you've moved the Keyspan adapter, the USA19H4b13P1 doesn't exist anymore and your software will not be able to find your serial device. HOWEVER, if you point your software to KeySerial1, you will be not have to worry about the port number changing since KeySerial1 will always point to a defined device (see the rules above).
- What MIDI devices are compatible with my Keyspan device on Mac OS 8.x - 9.x?
- Keyspan Din8 externally clocked serial ports (is ports on SXPro, USA28X, USA18X) support MIDI at the hardware level however you still need to have some of MIDI software (ie FreeMIDI or OMS) that can communicate with the Keyspan serial port. To determine if your MIDI setup will be compatible, please read the following: If your MIDI device is compatible with FreeMIDI (http://www.motu.com/), yes. Please visit MOTU's web page for additional requirements for FreeMIDI. If your MIDI device uses OMS (by Opcode), please note that the OMS software itself is not compatible with with ANY USB to SERIAL adapter. In some cases, you may be able to get OMS devices to work using FreeMIDI's OMS emulation mode. OMS will not work natively through Keyspan serial ports when using Opcode's software. If your MIDI devices does not use FreeMIDI or OMS (ie it uses Apple's MIDI system or some other software), your MIDI device will not be compatible. IMPORTANT NOTE: This applies to Mac OS 8.x to 9.x. Keyspan does not support MIDI on Mac OS X or Classic (Mac OS 9.2.2 running within Mac OS X)
