[PoliKom]®-200C, the optical modem

The special features of this equipment are:

• low price;
• attractive mass-and-size indices;
• the periodical of events before the energy-independent memory, which stores date, time and the nature of event;
• control according to joint RS-232 with the aid of the standard ANSI- terminal;
• the load of the new version of software based on the personal computer;
• mapping the current state by single indicators, notification about the emergency by sound signal;
• control capability besides the local and remote equipment;
• the small energy consumption (less than 3 W);
• the period of the guarantee of 5 years.

Diagram of the start:

The optical modem Of [poliKom]®-200[S] allows wide control capabilities with the aid of PK:

• monitoring the local and remote equipment before the regime of real time;
• the reconfiguration of the local and remote equipment (including the installation of trains);
• the survey of the periodical of the occurred events on the local and remote equipment.
