Gateway GW-23
The Gateway GW-23 acts as a local concentrator of I/O and
protocol converter for peripheral units (Subsystems) for
geographically distributed connections to a security
supervision center (LMS /CMS) via X-28, ISDN/D,
Ethernet/TCP-IP, Token Ring/TCP-IP lines and/or switched
lines.
It can replace previous model GW-22.
Features
• Low-cost, high performance unit for distributed security
applications. Based on i386 CPU with MS-DOS.
• Connection capabilities for up to 3 local security control
units, (only 2 units if switched line is also used); e.g.
intrusion, fire, gas detection, CCTV
• Support for alarm reporting and remote unit control via WAN
(Wide Area Network); network connection is via a serial
adapter interface (X.28 PAD / Over-Voice adapter) or an
Ethernet/Token Ring adapter
• Switched-line protocol for backup purposes can be
optionally selected
• Optional direct I/O signal acquisition and control for simplest
interface solutions
• The GW-23 is composed by :
- Processor board with 4 serial ports
- optional I/O board for digital signal processing
- Back-plane board for connections and power regulation
- optional modem board (X.32 bis) for switched line
• Processor board equipped with 4 serial channels, Flash
EPROM, RAM, RTC, LonWorks™ communication co-
processor, configuration dip-switches, diagnostic LEDs
• I/O board capable of handling 8 or 16 opto-coupled inputs
(NO or NC) and controlling 4 or 8 relay outputs
• Back-plane board allocating two full-modem, D-Sub 9-pin
connectors and two screw connectors, power supply block
for direct 12/24 Vdc voltage source
• Modem board, complaint to X32.bis standards
• Memory buffers and Real Time Clock on board for storing
and time-stamping events autonomously
• Interactions among the subsystems. An incoming message
can trigger one or more control command messages
•
Telephone numbers and interaction tables are stored on the
128k Flash EPROM included on base module.
• For each communication lines two separate LEDs indicates
the TX/RX status
• Diagnostic LEDs for system vitality and failures on memory
• CE label: GW-23 complies with European regulations about
emissions and immunity
• The GW-23.xx is available in five configurations: one for
serial connections only, another for Ethernet/Token Ring
and two more with additional I/O signal processing (8 / 4 or
16 / 8)
• Optionally, a 230 Vac power supply with internal battery
backup is available, coded as PS-23
• Compact housing available, including pre-wired PS-23
