可選配件
The audio interface unit is designed for use with TOA's packet intercom system (IP network compatible intercom system) that employs the packet audio technology. It can be connected to an existing local area network (LAN) or wide area network (WAN).
Network shall be made possible using RJ45 connection via switching hub. Network interface shall be I/F 10BASE-T/100BASE-TX (Automatic-Negotiation) Auto MDI/MDI-X compatible Network Protocol TCP/IP, UDP, ARP, ICMP, HTTP, RTP, IGMP.
By connecting the audio interface unit to a LAN via its RJ45 connector shall make it possible to broadcast public announcements by interfacing to an existing public address system. Other audio signals can be broadcast, such as BGM (background music), signal tones and chimes via the MIC/LINE balanced input. The audio input shall have its own independent volume control. The recording of conversations and paging calls of master stations, intercom telephones, and outside telephone lines shall be made possible by interfacing to an external recording device by utilising the isolated audio balanced output connector and controlled by the output connector closed contact.
The unit shall have a time synchronisation input and 8 contact inputs and outputs for the purpose of broadcasting pre-recorded internal and external audio files at a predetermined time via it's built in timer.
The audio interface unit shall have indication lamps on the front panel displaying:
LNK/ACT lights green when connected to a network, and flashes while transmitting or receiving data. STATUS continuously lights red while data is written to an internal storage medium. POWER lights green when power is supplied to the unit. SIGNAL lights green when audio is present and PEAK lights red when audio input reaches its peak. There shall be a RESET key on the front panel to reactivate the unit.
The audio interface shall include dedicated software that will enable centralised control and log verification and system maintenance from a personal computer. Line supervision can also be performed using a personal computer and Internet browser. The unit shall be able to interlock with an electronic lock system or CCTV surveillance system by way of contact input/output control function.
Power requirements shall be 220 – 240V AC.
It shall use only one-half EIA component rack space and its dimensions shall be 210 (W) × 44.3 (H) × 267 (D) mm (8.27" × 1.74" × 10.51") Weight shall be 1.7 kg (3.75 lb.) and finished in black pre-coated steel plate. Alternatively, the unit can be free standing or wall mounted.
Optional extras: MB-15B-BK rack mounting bracket (for rack mounting one unit). MB-15B-J rack mounting bracket (for rack mounting two units). YC-850 wall mounting bracket manufactured by TOA Corporation.
