ASM-31 multirate sync/async shortrange modem

Note: The ASM-31 has been discontinued.  Contact us about your application and we will do our best to recommend a suitable alternative.

ASM-31 is a multirate sync/async shortrange modem that operates in full-duplex mode over 2-wire twisted pair lines, at selectable data rates from 1.2 kbps to 128 kbps. The RAD ASM-31 uses 2B1Q line coding and transmits data in full-duplex up to 5.5 km (3.4 miles), independently of the data rate. An adaptive equalizer provides noise immunity and high performance over low quality lines. The ASM-31 DTE interface options include V.24/RS-232, V.35, RS-530, X.21, G.703 Codirectional (64 kbps), Ethernet bridge, and Ethernet router. The line connection is provided via an RJ-45 or a 3-screw terminal block connector. The unit is configured using internal jumpers and switches.

ASM-31 can be ordered as a standalone unit or as a single modem card for the 19-inch RAD ASM-MN-214 rack. Diagnostics include local analog, local digital, and remote digital loopbacks. Front panel LEDs indicate data receive and transmit, control signal status, loopback test state, and synchronization loss. Line interface circuitry protects against lightning and power surges.
