Summary

DV-Mini units have been optimized for systems where the number of Inputs/Outputs is limited, and are non-expandable. They are the perfect choice for sites having only one transmitter.

Connectivity Options:

Product Code Hardware Site Connection
DV-Mini-1 Internal dial-up modem; andEthernet connection for IP – Landline telephone- Analog mobile Telephone (with RJ-11 connector)- GSM (Hayes compatible)- Satellite (Hayes compatible)- Microwave/Radio Link- Internet, WAN, LAN over secure IP
DV-Mini-2 Serial port to accomodate an external Hayes-compatible modem1 (modem not included);Ethernet connection for IP – Landline telephone- Analog mobile Telephone (with RJ-11 connector)- GSM (Hayes compatible)- Satellite (Hayes compatible)- Microwave/Radio Link- Internet, WAN, LAN over secure IP

Features

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.
