Hull Speed’s LDM-192 and LDM-192EC Limited Distance Modems are capable of transmitting and receiving up to 19,200 bps of asynchronous or synchronous data over point-to-point or multi-point private cable systems or local unloaded metallic data circuits.
These multi-purpose units operate in either full-duplex or half-duplex modes over 2-wire and 4-wire lines.
The LDM-192EC unit is for synchronous applications requiring external or slave clocking. All other functions are
the same for both units.
Features include selectable data rates, local loopback, automatic equalization, transmit/receive speed selection, selectable transmit level, receiver sensitivity, line termination, carrier control and five interface LEDs. Selectable control options and Request To Send (RTS) and Clear To Send (CTS) delays are available.
