Overview
The Digital Acoustics IP7 Desktop models are IP (Internet Protocol) based
Intercoms that provide the functional audio equivalent of the basic "push to
talk" intercom. Simply power it up, connect it to a 10/100 Ethernet switch,
configure its IP address information and communicate to a PC running
TalkMaster™ software.
The IP7 Desktop models replace the previous ii3 series Desktop Intercoms.
Refer to the bottom label to ensure you have an IP7 series Intercom.
Standard features include:
• Integrated microphone and speaker
• Talk to/from an IP7 Desktop to host PC server
• High quality, clear transmit and playback audio
• Hands-free operation for the end user
• Highly scalable and seamless expansion
• Static or DHCP compliant IP assignment
• External 9VDC power
• Optional PoE (802.3af) available
• Available with “surface mount” bottom plate
• Field upgradeable OS using internal Flash memory
The IP7 Desktop must be configured using the TalkMaster™ software before
being used. Please consult the configuration section of the software manual
for details.
