Frequently Asked Questions


Technical

  • The device I am connecting my UniGuard to is acting very strange after connecting the UniGuard.
    MAKE SURE YOU USE ONLY THE CONNECTORS AND CABLES SUPPLIED BY CDI WITH THE UNIGUARD. USE OF ANY OTHER CABLE OR CONNECTORS CAN CAUSE PROBLEMS TO THE UNIGUARD OR THE CONNECTED DEVICE!
  • I am connecting to a PBX or other DCE device and the UniGuard drops the call after authentication.
    Most PBX ports are configured as DCE devices and require a Null Modem connector to operate with the UniGuard. The UniGuard is also configured as a DCE so it needs a null modem connector to communicate with another DCE. You can use a null modem adapter or call CDI support for a CDI null modem connector.
  • I want to know about the UniGuard's internal modem.
    The UniGuard contains a MultiTech MT5634ZBA V90 modem. When working on Windows 95, Windows 98 or Windows NT platforms, this modem should be added to the modem list in the Windows Control Panel.
  • Are UniGuard units flash upgradeable?
    Yes, from version 7.01 and up. This can be done automatically from the DDM.
  • Are there any special settings that the UniGuard needs to be set for when working on Windows 95, Windows 98, or Windows NT platforms?
    Yes, the baud rate, data bits and parity of the UniGuard should be the same as the host application it is connected to. The Host to Modem Access option should be set for Enable with Bypass.
  • Are there any specials settings for Dial up Networking?
    When dialing into a UniGuard using HyperTerminal dialout or Dialup Network, the option Bring Up Terminal After Dialing under Connection control should be Enabled (checkmarked).
  • Are there any special settings that the UniGuard needs to be set for when connected to a Unix host system?
    Yes, the baud rate, data bits and parity of the UniGuard should be the same as the Unix host application it is connected to. The Host to Modem Access option should be set for Disabled. This prevents any terminal messages from confusing the UniGuard.
  • Are there any special Issues with Sun Solaris serial ports?
    Yes, We offer a special connector for the SUN Sparc Station that overcomes the erratic behavior of this port when connected to a dial modem. There are also changes that need to made to the etc/default/login file.
  • Are there any issues connecting to Cisco routers?
    When the UniGuard is connected to a Cisco Router (2500 series, 4500 series, 3600 series) a special host adapter can be provided between the UniGuard host port and host application. Contact CDI about this special adapter.
  • After the user successfully authenticates and is then connected to the host application, the call drops.
    DTR (data terminal ready) is not asserted from the host application, so the UniGuard modem drops the call. The connection between the UniGuard host port and the host application is suspect. Check the host and/or host application to determine if DTR is present. If not, fix the host. Check to see that the host devices is configured as a DTE (Terminal) if not a null modem connector will be needed. Otherwise contact CDI Technical Support.
  • Invalid authentication between a remote DES-Modem and UniGuard.
    Make the sure the remote user enters the proper User ID and Password. Make sure the DES-Modem unit ID and its authentication key are the same as the one programmed in the host UniGuard's database.


Sales

  • Does the UniGuard work with Windows 95, Windows 98 , Windows NT , Unix, Linux, Solaris and other platforms?
    Yes. The UniGuard is independent of the operating system.
  • Can the UniGuard device be shipped overseas?
    Yes, we can ship to all counties on the US export list. Depending on the country, a specific power supply will be supplied. An additional cost is involved for international modem requirements.
  • Tell me about the UniGuard's internal modem ?
    The UniGuard contains a MultiTech MT5634ZBA V90 modem. When working on Windows 95, Windows 98 or Windows NT platforms, this modem should be added to the modem list in the Windows Control Panel.
  • Are UniGuard units flash upgradeable?
    Yes, from version 7.00 and up. This can be done automatically from the DDM.
  • Does UniGuard unit work with PcAnywhere, Reachout, Lap Link, or other remote control programs?
    Yes. The UniGuard operates just like a standard modem to any communications program.
  • Will the UniGuard work with an internal PC modem?
    No.
  • Does the UniGuard come without its own internal modem?
    Yes, in this case an external modem can be used with the UniGuard.
  • What is the highest speed for encryption (communication from a remote DES-Modem)?
    38400 baud (when set for Single DES) and 19200 baud (when set for Triple DES.) A faster version of the UniGuard (UniGuard-DDM) can run at 38400 Baud Triple DES.
  • Can the UniGuard be set for Triple DES encryption?
    Yes
  • Can a UniGuard operate in synchronous mode?
    No, asynchronous mode only.
  • What types of authentication does the UniGuard offer?
    RSA SecureID (built in, no need for ACE server connection), Password and ID, Callback, Challenge Response Token, Password and ID/ encryption, Full Triple DES encryption
  • Does the UniGuard have an optional network interface port?
    Yes all CDI products have an optional network interface.
