Leased line and dial-up analogue modems

DAVANTEL has a complete range of analog modems for dial-up and leased lines applications specially designed for industrial environments.

There basically three modem families:

MAPPLEX (AM1). Up to 28,8 Kbps over PSTN and 2-4 wires leased lines. RS-232 and RS-485 (x2) data interfaces. Universal power supply (both AC and DC on same power supply)

• MAPPLEX-485: RS-485 (x2) interface for multiple data terminal connection (p.e.:electricity meters)
• MAPPLEX-232: RS-232 interface

You can download the PDF datasheet here.

MABUX (AM2). Up to  33,6 Kb/s over PSTN. RS-232 user interface. Error correction and data compression.

AM-FSK. Low speed FSK modem (up to 1200 bps) over 2 and 4 wires leased lines. Standalone and 19'' rackmount format. PDF datasheet here.

All the above cards can be inserted in a 19'' 3U chassis with both 220Vac and -48Vdc power supplies available >>> PDF
