(Rarely asked questions)

Q. What NTDS interface types does the converter support?

A. The Converter supports all four parallel types:
NTDS Slow (Type A)
NTDS Fast (Type B)
NTDS Anew (Type C)
NTDS Fast Anew (Type H)
As well as NTDS Serial (Type D) and NATO Serial (Type E)

Q. Does the converter support Computer, Peripheral, and Inter-computer modes?

A. Yes, the user can configure an interface to use any one of the three modes.

Q. How do I configure the converter for my application?

A. There are two ways of configuring the converter for operations. First, the user can configure the converter using the serial terminal interface by connecting a PC or terminal to the RS232 console port. The alternative method is to configure the converter using a network application. In either case, the user can save the configuration in the converter’s nonvolatile memory. Once the configuration is saved the user does not need to be concerned unless a change is required.

Q How many NTDS interfaces does a NTDS converter support?

A. This is dependent on which converter you purchase. A single interface with Power Over Ethernet (POE) or a standalone powered unit. A multi-interface unit is available that supports up to four interfaces. The multi-interface unit supports POE as well as a stand alone configuration.

Q. How do I communicate with the converter using Ethernet?

A. First, the converter is configured to be either a network server or client. The user application initiates communications based on this configuration. All network communications are performed in accordance with the converter interface design specification.

Q. Do I have to maintain the NTDS protocol over the network?

A. No. The NTDS converter performs all of the low level interface communications. This allows the network application to only be concerned about sending and receiving application messages.

Q. Is there time synchronization between the converter and the application?

A. Yes. The converter will maintain time synchronization with the network application through one of two methods. One method is to configure the converter to use Network Time Protocol (NTP) communications. The second method is use the converter time synchronization protocol as defined in the user manual. In both cases an external device must provide a time for the converter to use. In the case of NTP, a NTP server must be available so the converter can receive time messages. In the case of the converter time synchronization method a network application must initiate and maintain time synchronization.

Q. Can I use different network protocols?

A. Yes. You can configure the converter to communicate using UDP or TCP communications. Each interface is independently configurable, assuming you have a multi-interface converter.

Q. Does the converter provide diagnostic information?

A. Yes. The user can query the converter for NTDS interface communication statistics.
