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.

INSTALLATION Mounting The AI-SRVR is designed for mounting in an industrial enclosure or wiring closet using either set of the provided mounting hardware listed below: TS-35 DIN Rail Mounting Panel Mounting DIN rail clip Panel mounting bracket 4-40 screws, pan-head (2) 4-40 screws, flat-head (4) For quick snap-mounting onto TS-35 mm DIN rail, a DIN rail clip is pre-attached to the back of the enclosure with two #4-40 pan-head screws. - Page 6 If using a grounded secondary transformer, refer to Figure 10. If needed, two auxiliary power supplies are available from Contemporary Controls: the AI-XFMR is for 120 VAC primary power and the AI-XFMR-E uses 230 VAC. AC Powered with Battery Backup —...

FIELD CONNECTIONS The AI-SRVR Series is available in several transceiver options for connecting to an ARCNET LAN. Each transceiver is matched to a particular cable type and identified by a three-character suffix appended to the model number. - Page 8 TB5 — Twisted-Pair Bus The CXB transceiver can be modified to drive a balanced cable system. This configuration is called TB5 and it supports shielded or unshielded twisted-pair cable such as Category 5. To support the popular modular plug connectors, dual RJ-45 jacks replace the single BNC connector. Follow the connector pin assignments on page 3 when preparing cables for TB5 use.
- Page 9 Termination Each end of a segment must be terminated in the characteristic impedance of the cable. A 120-ohm internal resistance can be invoked with a jumper on the EIA-485 daughter board. With the middle jumper inserted at E1 on the daughter board, 120 ohms of resistance is applied across the twisted-pair.

485X — AC-Coupled EIA-485 The AC-coupled EIA-485 transceiver offers advantages over the DC- coupled version. No bias adjustments are needed and wiring polarity is unimportant. Much higher common mode voltage levels can be achieved with AC coupling because the transformer coupling has a breakdown rating of 1000 Vdc. - Page 11 When contacting one of our offices, just ask for Technical Support. Warranty Contemporary Controls (CC) warrants this product to the original purchaser for two years from the product shipping date. Product returned to CC for repair is warranted for one year from the date that the repaired product is shipped back to the purchaser or for the remainder of the original warranty period, whichever is longer.
