MAC EXpansion Module - MEXM-1
Multiply your MAC's Input and Output points *
Daisy chain MEXM-1 units together and:
Add up to 128 extra Metering inputs to any one of your MAC units Add up to 192 extra Status inputs to any one of your MAC units
Add up to 72 Relay outputs to any one of your MAC units
For example, adding a single MEXM-1 to a MicroMAC yields a total of 32 metering inputs, 32 status inputs and 32 relay outputs for a very low price. These extra I/O's are directly integrated into the MicroMAC's control structure, therefore taking full advantage of the MAC's powerful control, monitoring and automation functions.
Maximum total I/O count for different types of MAC units by daisy-chaining MEXM-1 units together:

AM/FM Broadcast Monitor - FMBM
Davicom's AM/FM Broadcast Monitor offers a surprising number of advanced features in a compact, low-cost package. Remotely controllable through Davicom's MAC line of intelligent site monitoring systems, the FMBM can also be manually configured and operated.
It offers the following features:
Synthesized tuning
Non-volatile configuration storage
On-site monitoring of transmitter power
Off-air monitoring of receive signal strength
FM deviation measurement and alarms
Carrier frequency measurement and alarms
RDS/RBDS decoding
Balanced audio output on back panel and headphone output on front
All alarms levels are settable by the user, locally or remotely
Full remote control and monitoring through any Davicom MAC with USB interface
Alarm contacts for: stereo absence, high deviation, low deviation, low power, carrier frequency, drift
Designed for full and easy integration into the MAC's powerful control and monitoring structure, the FMBM gives you the benefit of remotely monitoring the key RF parameters of your AM or FM transmitter to ensure regulatory compliance.
Digital TV Transmitter - TVTX
The Scientel Digital TV transmitter is an 8-VSB professional VHF exciter designed to be used in stand-alone applications or as a driver for higher power amplifier stages. The transmitter is highly reliable, using only passive cooling and including RF output self-monitoring functions. Remote Control/Monitoring can be accessed through a 50-pin CHAMP® connector fully compatible with Davicom MAC units. Two units can be connected together in a master/slave configuration for backup transmitter operation.
