PS-20
The Gateway GW-20 acts as communication front-end
of a presentation system that could be either a LMS
/CMS or a foreign system. It complies with latest
European standards for emissions and immunity and
replaces the GW-00
Features
§ High reliability multi-processor, master-less
architecture
§ Multiple protocols and multiple/selective routing
§ Interactions among the subsystems: an incoming
message can trigger one or more command
messages to other subsystems
§ Single or double internal power supply unit PS20
(100-240 V a.c.) with built-in battery backup
providing up to 3 hours autonomy;
alternatively, external 12V DC power source when
longer backup is required.
§ Processor boards (Pads) are equipped with RAM,
FLASH EPROM, RTC. and 4 serial channels. The
software installed specializes each Pad in a
communication function
§ GW-20 allows for modular configurations of up to 7
Pads:
- Supervision Pad
- CMS Pad for connecting up to 4 LMS/CMS
systems
- to 5 Subsystem Pads for up to 20 subsystems
- to 5 Net Pads for up to 20 2nd-level gateways
- Nise Pad for a Landis & Staefa Control System
MS-2000
- 1 FHI Pad for a Foreign Host
§ Communication among boards using LonTalk™
protocol
§ CB-100 panel connection capability; local printer
for technical data logging
§ Software tools for configuration available;
configuration data stored on Flash EPROM
§ For each communication lines two separate LEDs
indicate the TX/RX status
§ Diagnostic LEDs for Power supply (mains fault,
power supply fault, battery fault and battery low),
Pads, and lines on the front panel
§ Standard 19“, 3U housing for max. 7 electronic
boards,
200 mm deep, suitable for rack mounting
§ The boards can be accessed from the front panel
and can be extracted from the housing; all serial
connections are via 9-pin, D-Sub connectors
mounted on the rear panel.
