The Davicom MicroMAC is designed to handle your small-budget remote-control & monitoring needs. I/O capability includes 8 metering, 8 status and 8 relays, and communications is achieved over dial-up or IP networks. The MicroMAC operates with the same Graphical User Interface (GUI) as other MAC products, so personnel can easily control all sites, from the smallest to the largest, with a unit from the Davicom MAC family.

The MicroMAC is just as intelligent as other MAC units with extensive condition-driven and event-driven programming capabilities. It boasts the industry’s widest choice of communication means, including: voice/DTMF, PC, FAX, E-Mail, pager, text messaging and Web Browser. It also allows easy access via a Blackberry @ or smart phones.

INPUT/OUTPUT CONFIGURATION OPTIONS:

	INPUTS			OUTPUTS	PORTS
PRODUCT prefix	Metering (analog)	Status (digital)	Audio	Relay/ O/C	Serial (RS-232)
MicroMAC	8	16	4	16	4

VIRTUAL INPUTS/OUTPUTS AND TIMERS:

Virtual Logic Gates	128	Program conditional actions and complex logic functions, to control relays, set qualifiers, view flags or other events. In addition, MAC units have qualifier and inverter functions on all inputs.
Virtual Relays	128	Use the latch and pulse functionalities to qualify conditional actions without using physical relays.
Timers	128	Set date/time events & windows. For example, AM antenna pattern changes with specific time windows for each month.

CONNECTIVITY OPTIONS:

PRODUCT suffix	MAC HARDWARE	SITE CONNECTION
-1	Internal dial-up modem. Ethernet connection for IP. USB connection for up to 4 USB modems via USB hub (modems and hub not included).	Landline telephone Analog mobile telephone (with RJ-11 connector) GSM (Hayes compatible) Satellite (Hayes compatible) Microwave / Radio link Internet, WAN, LAN over secure IP
-2	No internal modem. Ethernet connection for IP. USB connection for up to 4 USB modems via USB hub (modems and hub not included)

FEATURES:

INPUTS/OUPUTS

MicroMAC units use industry-standard DB25 female connectors for all its Input/Output points;
Optional I/O interface board (MIOBU) to bring connections out to screw terminals.

REMOTE CONTROL, MONITORING AND INTERROGATION

Ethernet jack allows fully integrated IP capability, including the ability to send alarm messages through e-mail;
Telephone jack allows remote control/monitoring/interrogation through landline. Send commands using DTMF tones1;
USB port allows remote control/monitoring/interrogation through GSM, satellite or landline external Hayes-compatible modems

LOCAL CONTROL, MONITORING AND INTERROGATION

USB port to connect to a laptop (from the MicroMAC’s front panel).

SITE MAINTENANCE

Local push button (on the MicroMAC’s front panel) allow on-site technicians to work safely.

ON-SITE ANCILLARY EQUIPMENT

Ethernet jack can ping up to 32 on-site ancillary equipment (or connect a master MAC unit to a slave MAC unit);
USB ports #1 to #8 can control on-site ancillary equipment in pass-through mode (via external hub).

ON-SITE PERIPHERALS

USB port to connect, for example: external memory for data logging, an external modem, etc.

FAILURES

Plug for an AC/DC converter to monitor power fail on mains.

No voice interface and no DTMF control when external modems are used.
