All Davicom units have the capability of taking

input readings at a 1-Hz rate and storing them to

an external USB device such as a Flash memory

stick or hard disk drive. Up to 32 inputs can be

simultaneously sampled and stored in this manner.

Readings can then be browsed and/or transferred

at a later date to facilitate troubleshooting of

intermittent site problems. Note that a data

connection with adequate bandwidth must be

available to download the complete site data log.

Alternatively, small snippets of data for particular

dates and times can be transferred over a modem

connection, or the USB memory device could be

physically brought back from the site following a

normal site visit.

The DavLink site communications application can

be used to view site readings in graphical form

when connected live to a site. This allows easy

visualization of site trends and problems.

Simple Network Management Protocol (SNMP)

All Davicom units, except the DV-Micro, have a built-in SNMP agent to allow monitoring and control from a

central SNMP manager. When activated, this agent allows remote SNMP management systems to perform

GETs, SETs and to receive traps from Davicom units.

In addition, all Davicom units, except the DV-Micro have a built-in SNMP Manager that allows them to take

readings, set controls and receive alarms from SNMP enabled devices such as transmitters. This monitoring

and control is achieved over a simple RJ-45 TCP/IP connection between the Davicom and the device, thus

greatly facilitating interface wiring. This I/O functionality is fully integrated into the

Davicom’s powerful Virtual Logic Gate structure to take full advantage of all

of the Davicom features.
