Comtrol Launches DeviceMaster LT16 – secure device server for serial to Ethernet device communication

DeviceMaster LT16MINNEAPOLIS, Minnesota — March 20, 2014— Comtrol Corporation, a leading manufacturer of industrial device connectivity products, today released the DeviceMaster LT16, a highly secure, compact device server for easy integration of serial communication devices into LAN, Internet, or cloud-based systems.

The DeviceMaster LT16 easily links serial communication devices into existing Ethernet networks for remote diagnostics, management, and data collection. With a low-profile design, 16 serial ports, and Windows and Linux driver software, it is ideal for network-enabling barcode scanners, weigh scales, card readers, and POS equipment.

For those with existing systems, the DeviceMaster LT16 utilizes serial port wiring compatible with widely deployed device server models from Digi International Inc. This compatibility makes the LT16 a cost-effective replacement for legacy systems while maintaining investment in existing cabling and infrastructure.

For compliance with new and evolving data security practices, the DeviceMaster LT16 includes the strongest security and encryption features to support deployment in government, financial, and point-of-sale applications where strict privacy and data standards are crucial.

“With security breaches recently topping the news, now more than ever, companies are looking to modernize their networks and serial communication systems,” said Comtrol Director of Product Management David Boldt, “The DeviceMaster LT16 delivers the latest networking and data security features needed to immediately bring systems up to speed.”

The DeviceMaster LT16 is available in two models for installations requiring AC power or direct DC power systems. It includes Microsoft® certified driver software supporting the latest Windows operating systems and TTY drivers for popular Linux distributions. Comprehensive PortVision® DX network management software is included with each product for configuration, monitoring, and remote management within any network size.

A Technical Support FAQ: Testing serial ports in RS-232 mode

Posted by

Question:   How do I go about testing serial ports in RS-232 mode?

Testing Serial PortsAnswer:   For DeviceMaster® products:

Test the serial ports using the Test Terminal application in PortVision® DX (or PortVision Plus) and the Loopback plug provided with the DeviceMaster.

If you need to create a loopback plug, you may download the instructions HERE.

Instructions for testing serial ports:

Stop all applications that may be accessing the ports such as RAS, RRAS or any faxing or production software.  See the appropriate manuals for instructions on stopping these services or applications.  If another application is controlling the port, or if the driver had not been properly configured, then Test Terminal will be unable to open the port and you will receive an error message.

Remember to restart the application once testing of the ports has been completed.

A Technical Support FAQ: Problem uploading firmware to DeviceMaster®

Posted by

Question:   

Why can’t I upload firmware to my DeviceMaster?

Answer:

The most common reason for firmware updates to fail is due to a timer that needs to be reconfigured called the “Bootloader Timeout.” This timer can only be configured when an IP address has been configured in the DeviceMaster and IP communications are active (such as being able to ping the DeviceMaster or open the web page in the DeviceMaster) There are a few different methods to modify this timer.

DeviceMaster PortVision Plus

Use PortVision Plus:

This method is dependent on the version of SocketServer or NS-Link installed in the DeviceMaster.

  • Double-click on the DeviceMaster in PortVision Plus. This opens the “Configure Device” page.
  • At the bottom of this page will be displayed the “Bootloader Timeout:” value.  If the option is not present, one of two conditions exist.
  1. The firmware is too old in which case use the Telnet method following
  2. PortVision Plus is not able to communicate to the DeviceMaster via TCP/IP
  • Change the value to 45 and click on the “Apply Changes” button and then the “Close” button.  Now try to upload the firmware.  If it is successful, then set the Bootloader Timeout back to the original value.

DeviceMaster RTS Traffic Cabinet - Chandler, AZChandler, Arizona

Traffic cabinets in the middle of the hot, arid desert climate of Chandler, Arizona required traffic control devices to be able to withstand 160°F temperatures and to allow easy expansion of the city’s traffic system.

Chandler’s traffic engineers chose Comtrol’s DeviceMaster® RTS to meet these requirements.  With its PortVision® Plus feature-rich software, wide operating temperature range, reliability and ease-of-use, the DeviceMaster RTS was the perfect solution to control PTZ (pan, tilt, zoom) traffic cameras, change signal timing for road construction, manage short-term maintenance needs, and even control demands for special events or accidents.

A Technical Support FAQ: Updating Your DeviceMaster®’s Firmware

Posted by

Question:   

I recently uploaded the latest firmware on my DeviceMaster. Now, after the upgrade, it shows SocketServer 8.0 where it would normally give the NSLink version within PortVision Plus. Is this correct?

PortVision Plus DeviceMaster device serversAnswer:                                                             Yes, this is correct. SocketServer and NS-Link have been incorporated into a single bin (binary) file which may either display the name nslink-8.00.bin or socketserver-8.00.bin, depending on the location it was downloaded from. By default, once loaded, the file will show SocketServer in both the web page and PortVision Plus until a driver begins communication with this particular DeviceMaster. Once a driver establishes communications, the firmware will now ‘magically’ indicate that it is NS-Link without the driver having to upload that firmware to the DeviceMaster, or the DeviceMaster being rebooted as in the past. If SocketServer does not change to NS-Link, then a driver loaded in the PC is NOT in communication with the DeviceMaster.

This new firmware also has other capabilities that that when used together provide much more information for diagnostic purposes.

For example —  If SocketServer is displayed in PortVision Plus, there is no driver yet communicating with this DeviceMaster indicating one of three things:  that the driver has not yet been configured for this DeviceMaster or has possibly been disabled or is being blocked by some network configuration such as a firewall.

Once NS-Link is displayed, the web pages may be opened and the home page will display the MAC or IP address of all of the PC’s sharing this DeviceMaster unit that the driver is installed in. The serial ports that are open from that particular PC will also be displayed as being open on the identified PC.
