The 2400 bps Half-InchModem™ measures only 1.0” x 1.0” x 0.3”. This feature-rich miniature module is fully self-contained including built-in data pump, modem controller and on-board International DAA. The complete solution provides system engineers the flexibility to include modem functionality in system products with minimal engineering resources.
With Radicom’s proprietary code, the modem provides the fastest possible dial-up connections for Point of Sales (POS) operation. Using two 240HM family modems, point to point, allows independent POS operation without having to use a central site modem or existing software controlled billing systems.
Standard features of the modem include data rates from 300 BPS to 2400 BPS, V.22 bis and V.22 fast connect, Caller ID and low power sleep mode. The modem also provides enhanced features such as Line-in-Use detection, Call waiting detection, Remote hang-up and Extension pick-up detection. The modem has built in Digital Line Guard (DLG) protection which can detect an over current situation on Tip and Ring. Used to protect the modem when accidentally connected to a digital telephone system.
The modem is ideal for POS Terminals, Set-Top Boxes, ATM Machines and other embedded applications which require fast-connect speeds, low power consumption and cost-effective data communications. Features:
