Davicom, maker of the MAC line of monitoring equipment, is planning additions to its product family and will talk about them at the 2011 NAB Show.
The Mac Expansion Module, MEXM-1, adds extra input/output capability to any MAC product. Each MEXM-1 adds 24 metering inputs, 24 status inputs and 24 relay outputs that are integrated automatically into the MAC’s control structure. Eight MEXM-1 units can be used together and, if connected to a MAC216, will provide a total of up to 144 metering inputs, 224 status inputs and 104 relay outputs. Metering input ranges cover ±2.5, ±5, ±10, ±25 and ±50V.
Also new is the AM/FM Broadcast Monitor, AFBM. It adds AM and FM signal monitoring capability to the Davicom-MAC line of products.
The unit has high- and low-level inputs to accommodate on-site and off-air monitoring. It can monitor AM and FM signal strength and power, AM modulation index, FM peak multiplex deviation, FM carrier frequency, stereo pilot presence, L & R audio and RDS strings, all with user-defined threshold levels. The AFBM interfaces to the Davicom MACs through a USB connection, or for older MAC units via GPIO signals.
Additionally, Davicom MAC’s firmware is being updated to version 5.41. Added is an SNMP Manager to the MAC’s I/O capability. This feature allows easy control and monitoring of SNMP-enabled devices such as transmitters. Currently in pre-release, Firmware 5.41 will be available for free download to Davicom MAC users in June.
