E5805A USB/RS232 Interface 1

E5805A USB/RS232 Interface

The E5805A USB/RS232 Interface is an intelligent, stackable expansion module that connects to a PC or server running Windows® 98SE, Me, 2000, or XP via the Universal Serial Bus (USB), providing high- speed serial connectivity.

Cabling the E5805A USB/RS232 Interface

Type A Type B

Plug the Type A end of the USB cable into the USB port located in the back of your PC or into an available USB port on a standard hub. Plug the Type B end of the USB cable into the back of the E5805A USB/RS232 Interface.

If the drivers are not already installed, go to "Installing the E5805A USB/RS232 Interface” on the next page.

NOTE

Installing the E5805A USB/RS232 Interface Drivers

The E5805A ships with the Driver and the Automation- Ready CDs. The Driver CD software must be installed for the product to operate. Once the Driver software is installed, the E5805A can be attached to a USB port. Your PC should be able to connect to it, and the four RS232 ports on the E5805A should appear as additional Windows® COM ports. These ports can be used by your PC to connect serial instruments and general purpose devices to the four port RS- 232 converter. The IO Libraries CD shipped with the E5805A allows you to use I/O libraries (for example VISA, VISA COM, and SICL) to do “instrument style” programming of instruments or devices. It also provides a suite of tools for connection management and interactive instrument control. If you are using VISA or other T&M specialized software to program instruments, or if you are using application software that does instrument control, you may want to also install the IO Libraries Suite.

Note: Drivers may not have received “Designed for Windows 2000” certification. If so, Windows displays a warning: Digital Signature Not Found. While the drivers may not be Windows certified, they have been thoroughly tested. Select “Ye s” to continue with driver installation.

Interpreting the System Status Light

Red: This light signifies a loss of USB communication with the host. If the loss is due to unplugging the unit, when the unit is reconnected the light will blink red for a few moments before turning green. Otherwise, the light indicates a problem with the drivers, which may need to be reinstalled. The red light also blinks during installation. Once the installation is complete, it should stop blinking.

Amber: This light signifies serial port activity on the E5805A USB/RS232 Interface. The amber light may also flash briefly during installation.

Green: This light indicates the serial ports are successfully set up and the E5805A USB/RS232 Interface is operating normally.

NOTE

The E5805A USB/RS232 Interface Utility Program

For all Windows Operating Systems

The E5805A USB/RS232 Interface configuration utility program, which is available from the Start menu, allows you to manage the serial ports of your 4 Port Interface product.

For Windows 98SE and Windows Me, the configuration utility is located in C:\WINDOWS\SYSTEM\EDGEPORT.EXE.

E5805A USB/RS232 Interface 7

E5805A USB/RS232 Interface

The General tab in this utility allows you to do the following:

1 Information - Check the manufacturing information related

to your device.

2 Configure - Reassign your device’s physical port to any

available Windows COM port number from 1 to 255 and give your device a user- friendly Device Name. This capability is particularly helpful if you have more than one device.

Port F lags - Configure performance options and special functionality on a per- port basis.

•Remap Baud: Setting the baud rate to 1200 baud will result in 230400 baud

•Fast Reads:

This flag is used when an application requires a read to complete immediately. In the read immediate case, the E5805A USB/RS232 Interface driver sends a request to the device asking for any buffered data to be sent. This buffered data will be included when the read completes. If this flag is set, the driver does not query the device for additional data.

•Fast Writes: When an application sends a write to the driver, by default the E5805A USB/RS232 Interface driver waits until all data has been transmitted out of the device before completing the write. When the Fast Writes flag is set, the write is completed even if data is still buffered in the driver and the device.

•Ignore Tx Purge: The IOCTL_SERIAL_PURGE request cancels the specified requests and deletes data from the specified buffers. The purge request can be used to cancel all read requests, all write requests, and to delete all data from the read and write buffers.

E5805A USB/RS232 Interface 9

E5805A USB/RS232 Interface

When the Ignore Tx Purge flag is set the SERIAL_PURGE_TXCLEAR command is ignored. The function does not purge the write buffer.

• Disable Plug & Play: (Windows 2k/XP only)

Do not let the serial port enumerator detect devices plugged into the 4 Port Interface.

•Timer Logic: (Windows 98SE only)

If the application uses PortSetReadCallBack(), the notification routine is only called when the number of bytes in the receive buffer is greater then the RX trigger. The Microsoft serial VxD also implements a timer that triggers and calls the notification routine if some amount of data is available in the RX buffer, but no new data has been received for ~200ms (receiver is no longer active).

We do not enable this behavior by default because of the nature of E5805A USB/RS232 Interface’s buffering. However, if you set the f lag, the read is completed when ~200 ms of no activity is detected.

Here is a comment from the code:

If the receiver is active, then do not complete this read. The problem is that the device buffers the RX bytes and we poll the driver. If we do not receive any bytes in 200ms we may report an erroneous event even if there are available bytes in the device or driver.

Tes t Ports - Performs a confidence test on the internal workings of the serial ports..
