FEATURES:

INPUTS / OUTPUTS
DV-Mini units now use industry-standard 50-pin Champ connectors for all its Input/Output points.
 
REMOTE CONTROL, MONITORING AND INTERROGATION
Ethernet jack #1 allows fully integrated IP capability, including the ability to send alarm messages through e-mail; 
Telephone jack allows remote control/monitoring/interrogation through landline. Monitor audio inputs live over the phone and send commands using DTMF tones; 
Serial port IOIOI-2 allows remote control/monitoring/interrogation through a GSM, satellite or landline external Hayes-compatible modem.
 
LOCAL CONTROL, MONITORING AND INTERROGATION
USB port to connect to a laptop (from the DV-Mini's front panel); 
Serial port to connect to a laptop or PDA2 (from the DV-Mini's front panel); 
Stereo headphone jack to locally monitor audio inputs (from the DV-Mini's front panel).
 
SITE MAINTENANCE
Local and pause push buttons (on the DV-Mini's front panel) allow on-site technicians to work safely.
 
ON-SITE ANCILLARY EQUIPMENT
Ethernet jack #2 can ping up to 32 on-site ancillary equipment; 
Auxiliary serial port can control an on-site ancillary equipment in pass-through mode; 
Auxiliary serial port can monitor for specific alphanumeric strings from an on-site ancillary equipment 3.
 
ON-SITE PERIPHERALS 
USB port to connect, for example: external memory for data logging, an external modem, etc.3
 
FAILURES
Plug for an AC/DC converter to monitor power fail on mains.
1 Only one external modem can be installed (with or without the optional internal modem). No voice interface and no DTMF control when the external modem is used.

2 Serial port adapter for PDA not included.

3 On future firmware releases.
 

 

For several years, leading broadcasters and first responder organizations around the world have been relying on efficient Davicom technology to remotely monitor and control their site equipment and reduce operating costs.

 
Davicom Systems features and benefits include:
Easy installation, set-up and operation.
Reliable proven in the field since 1994.
Stand-alone units that do not require a computer at the site.

Ports, relays, metering... are included. Package includes the power supply, I/O cables and interconnect panels.

Very intelligent and simple

Automated operations and manual control to minimize operational downtime.

Reduced site maintenance costs
Extensive log and remote measurements help diagnose and solve problems with fewer trips to the site.

Reduced overtime

Thanks to minor alarm muting functions.

Widest choice of means of communications including secure 128-bit* encrypted IP.

Redundancy
Dual-modem ready.
Robust
No moving parts such as hard disk drives or fans. Can handle electric fields of over 10 V/m and electrostatic discharges of 12 kV.
Easy upgrades
Battery RAM and Flash memory.

Direct monitoring of site audio via telephone or IP streaming.

Real-time access to site information from anywhere in the world.

Increased security at remote sites.

User-customizable interface that reflects the exact set-up of site equipment.

Single location management of all sites.
