CCOR I Protocol Modem Card
The Model MB-AM is an intelligent RF modem card which is designed to plug into ISA backplane card slots in a PC compatible computer. In most common installations, the unit is installed in an AM's OmniMCU™ . The MB-AM is an intelligent unit. The card has an embedded ‘386 microcontroller with 4 MB of RAM storage. The program is stored in a 256k flash memory, allowing remote downloading of a new operating program without removing the card from the MCU computer. Each MB-AM can poll a population of up to 2000 transponders at up to 250 polls per second. The MB-AM also has provisions for a plug-in FSK RF data transmitter, and 2 FSK RF data receivers. Since 6 modem cards can be installed in a typical MCU chassis, there can be up to 12 available receiver inputs. This is a very important feature which is provided to mitigate the effects of noise buildup on any single receiver. If one system segment becomes excessively noisy, the monitoring system will continue to operate on the remaining system segments without impairment. Both receivers as well as the transmitter are frequency agile. The operating frequency of the MB-AM, as well as the frequency of all the transponders it controls, is easily changed from an Omni2000™ software screen. The MB-AM also has 2 built-in RS-485 ports. These are used for a direct communications interface to monitoring equipment which is co-located with the OmniMCU™, such as headend performance and status monitoring equipment. The MB-AM is designed to communicate with transponders using AM’s monitoring protocols. Other versions of the unit are compatible with communications protocols used by other status monitoring equipment suppliers. Contact the factory for information.
