Nowadays a lot of attention is given to the hardware-software packages of the manufacturing equipment for modern electronic warfare complexes. Digital radioelectronic equipment processes the information incoming from receivers in real-time, converts it to the set format and transfers it to the second stage processing device - microcontroller or computer on the operator-s workstation. Unfortunately, the conjugation of all the equipment and the complex software is not always successful at the first connect. This article contains the description of the imitational stand created for RR complex software debugging. In the beginning of 2012 the task of developing the special software for manufacturing RR complex was set. There are a few principal restrictions - Microsoft Windows 7 operating system and Java, C or C++ programming languages are available to use. The solution was found in developing the equipment emulators for software debugging. Three main parts were distinguished considering the structure of a complex - antenna post of a PIP, group of ICP-s and a CP part. To conjugate these parts the information interchange protocols were developed together with the equipment developers. These protocols consisted of a multilevel description of an interaction, starting from physical level to the application level. Next step was the LAN setup with separate workstations and the software connection via networking protocols. The stand consists of 4 computers, imitating WS-1 PIP, WS-2 PIP, ICP and CP respectively, and an Ethernet switch used to setup the LAN. The amount of computers was three in the beginning of a development, but in order to see several workstation displays, one more was added. Computers connect via Ethernet switch using Ethernet cable (twisted pair, category 5e, RJ-45 plugs, direct wiring). After the local tests and debug iterations the software is expected to connect to the manufactured parts of a RR complex. For these purposes the PC which acts as a ICP group imitator, is being extracted from the LAN and the internet connection to the equipment is set up instead. Using this solution the software developers group can test the interaction with the equipment kept far away from the group location. As a result of the distance test the developers are able to check workability and interaction of the software and equipment without transportation of a complex components to an assembling place. Three parts of a imitation software were distinguished. The first one is an antenna post imitator, kept in a PIP. The antenna post transmits the result of a panoramic vision process, the condition of the panoramic vision device and the condition of a thermo regulator device. The second part is a Master ICP imitator, which receives the information gathered by antenna post, processes and completes it with the coordinate and tracking information and then transmits it to the PIP software. The third part is CP. PIP transmits the processed information about the radioelectronic situation in the complex responsibility zone to the CP. CP transmits the radiolocation information and the commands to single stations or to the complex overall to PIP. The interaction of imitators is decided to organize with TCP network protocol using the request-answer method. To prevent the compatibility problems of the imitational software the developing sides have to create interaction protocols. Those must consist of multilevel description of the interaction between software and hardware. The computer configuration of the imitating and training stands is to be chosen considering the computer configuration used in the manufacturing complex, with a short possible differences. If the configuration is not possible to be assembled, then it is necessary to calculate the minimum requirements for the computer and assemble with using the calculation results.
