Remote Storage Module (RSM)
The
Remote Storage Module
(RSM) is an optional data storage device which provides the ability to
automatically archive longer periods of recorded data.
The module:
Has an Ethernet interface to accept data from the VDR and a USB2.0 port which allows the
stored data to be retrieved and/or reviewed on any modern PC.
Sufficient to archive 160GB of data, or can be used to retrieve several previously secured data
sets.
When the RSM is supplied as a data retrieval device, a universal AC adapter is included. When supplied
with the extended archiving software module, universal AC and 24VDC power supplies are included.
The RSM is similar to the FRM, except:
It is not designed to survive extreme conditions.
It has a much larger storage capacity.
It is small and easy to transport.

External Data Interfaces
The
External Data Interfaces
, used to sense data signals from ship’s equipment in order to provide
61162/NMEA0183 compliant data sentences, are recorded via the NMEA Modules described earlier in
this documentation. Non-compliant data can be recorded using one (1) of the following interfaces:
DataAnalog
The DataAnalog Input Module monitors the status of eight (8) analog input signals and indicates the
voltage or current which corresponds to the equipment setting on each input channel via an NMEA-
0183/IEC 61162 format data sentence transmitted once per second. The DataAnalog interface has eight
(8) channels and can simultaneously monitor signals from four (4) separate systems while maintaining
isolation between them. This interface is ideally suited to measure the electrical indications for order and
response from four (4) shipboard systems (i.e., Rudder Order/Response, ME RPM Order/Response,
Pitch Order/Response, Bow Thruster Order and Response).
DataDiscrete
Discrete inputs can be monitored via Rutter Technologies’ DataDiscrete interface unit. Discrete inputs
are data items recorded simply as open/closed or on/off. These discrete inputs reflect their status by the
presence or absence of discrete voltage levels or by the closure of a set of relay contacts. The
