Stand-alone Asynchronous FSK Narrowband Modem

The MAS-2 consists of a 19”/1 s.u. chassis with an embedded single modem module type MAFP.

600 Ω input and output impedance.
Data format: Binary, serial. Asynchronous and anisochronous.
Modulation: Frequency-shift keying (FSK).
Transmission mode: V.23 Full-duplex over 4-wire and Half-duplex over 4 or 2-wire.
Transmission speed of 50, 100, 200, 600, 1200 or 2400 Bd (using a 4 kHz band).
Central frequency programmable from a wide range of values.
The data interface complies with specifications V.24 and V.28 of the ITU-T and RS-232C of EIA.
When operating up to 1200 Bd in superimposed band, it can share the channel of the PLC terminal with speech frequencies up to 2000Hz and with a teleprotection guard frequency of 3800 Hz.
Equipped with test devices for a rapid operational check.
Optical indications.
The firmware of the MAFP module can be updated from a terminal emulator program.
Compact 19″/1 s.u. chassis.
