AI-SRVR Series
ARCNET ® Server to Ethernet Client
INSTALLATION GUIDE
INTRODUCTION
The AI-SRVR performs as an ARCNET Server to Ethernet Client by
executing communication requests from an Ethernet client. Any number of
Ethernet TCP/IP clients can initiate requests to any node on an ARCNET
network. The AI-SRVR receives ARCNET packets and sends the data to
Ethernet clients and does the reverse for data received from the Ethernet.
To the ARCNET, the unit is just another node with no need of changes or
protocol overhead. It is transparent and uses dipulse or EIA-485
transceivers. Its Ethernet port accepts 10BASE-T or 100BASE-TX data
using TCP/IP and UDP.
AI-SRVR-8/ models use a special PROXY mode in which two units pass data
between eight nodes in two ARCNET LANs via the Ethernet. AI-SRVR-1/
models can also act as proxies but only for one node per LAN.
Coaxial bus is supported by CXB models (BNC connector). Twisted-pair
is supported by TB5 models (RJ-45 connector). DC-coupled EIA-485 is
supported by 485 models and AC-coupled EIA-485 by 485X models
(both models using 3-pin screw-terminal connectors).
Configuration is done by a Windows
® -based terminal-emulation program
such as HyperTerminal or PuTTy via an EIA-232 serial console port
(COM2). A second serial port (COM1) is for factory service.
The Ethernet port auto-negotiates data rate, duplex mode and flow control
(PAUSE for full-duplex, backpressure for half-).
The unit is powered from a wide-range, low-voltage AC or DC source
with redundant power connections for backup schemes. It comes with
the ability for either DIN-rail or panel mounting. The switch front panel
features a general status LED and there are LEDs for link status, activity,
and data rate of each port.
