Cupol-4MP

The retransmitter “Cupol-4MP” is intended for routing of information packets received over the radiochannel from object control panels “Cupol-4”, “Cupol-4L”, “Cupol-16”, “Cupol-TRS” and information packets received over the RS485 interface from control panels “Cupol-3”, “Cupol-16T”.

The device performs retranslating transmitted information packets (notifications) to a receiver over the specified routes. The retransmitter supports up to 512 receivers and up to 4 alternative routes for each receiver. Transmitting of the translated packets can be performed as over the radiochannel as over the wire line RS485.

The main application is a centralized or autonomous object guarding.

The retransmitter “Cupol-4MP” supports operation by two protocols: the protocol without confirmation and the protocol with confirmation (quitting, while operating with “Cupol-4MP”).

While information transmitting to receiver, the following communication channel can be used:

1. Radiochannel.
   The information from an object control panel is transmitted to a receiver over the radiochannel according to a specified route.
2. GSM (GPRS) channel.
   The retranslated information according to a specified route is transmitted over the wire line RS485 to “Cupol-GSM”, which performs the notification transmission over the GSM (GPRS).
3. Wire line RS485.
   The retranslated information according to a specified route is transmitted over the wire line RS485 direct to PC with appropriate software through the matching device “USB-485”.

While using the protocol with confirmation, in case of non-receiving the receipt from the receiver, the retransmitter moves to one of alternative routes to this receiver.

The retransmitter “Cupol-4MP” supports up to 256 local objects, at this, the retransmitter spies the communication channel status with each object and can (optional) leave telemetric information out for reducing the traffic cost. In case of connection violation with the object, the retransmitter transmits appropriate information notifications to CSC.

The retransmitter “Cupol-4MP” collects statistics from all “visible” objects, which compose the system “Cupol”. While receiving of each information packet over the radiochannel, the signal levels and noise levels are measured and averaged, number of received packets from each object are averaged per one hour. Statistics of all objects are stored into the retransmitter memory and available for reading.

Up to 32 devices “Cupol-3”, 16 devices “Cupol-16T” and 4 object control panels can be connected to Cupol-4MP over the wire line RS485.

The operation with the retransmitter is performed with help of the object control panel. The command menu, entered parameters and other information are shown in on a two-line symbolic display.

The equipment is operated in round-clock mode at environment temperature from plus 5 °C to plus 40 °C and relative air humidity up to 93% (at 40 °C).
