IPI-4 Converter

For AXS-100/200 Controllers

Installation Guide

Introduction

The IPI-4 Adapter is an integrated single-port PCB type
asynchronous serial communication gateway that seamlessly
converts the RS-232 port of a VisAccess AXS-100/200 controller
to 10/100 Ethernet V2.0 (TCP/IP).

The adapter enables a ‘Master’ AXS-100/200 controller to be
placed anywhere on a WAN/LAN or Internet based network and
still perform as if the controller was hard wired to the host
computer via RS-232.

The IPI-4 is shipped with Lantronix Programming Software for
browser based configuration of its network settings, serial-port
line settings, UART transmit and receive buffer trigger levels and
serial port flow control.

The IPI-4 also supports remote configuration, supervision and
management via EIRIS V4.6 (or higher) as well as AXSalert
(all versions) enterprise software.

NOTE: RJ-45 terminated Ethernet network interface cables are
not included with the IPI-4 converter.

CAUTION: It is important that the installer understand

and follow the instructions in this document. If you have
questions, call your local VT support representative.

Typical System Configuration

Any combination of eight Master/Slave AXS-100/200 controllers (each with its own address) can be networked together on a single
RS-485 data loop to manage up to 16 doors. Each RS-485 data loop requires that one Master controller (whose address is #1)
be equipped with an IPI-4 Converter for communicating via 10/100 Ethernet V2.0 (TCP/IP) with the host server machine.

Electrical Interfaces

The IPI-4 contains one female RJ-45 (8P8C) connector for
linking the device to the LAN/WAN Ethernet network switch or
router. This requires a standard network 8-pin RJ45 terminated
patch cable (not included)

The pin configuration of the RJ-45 connector is detailed below:

Two bi-color Ethernet status LEDs are built into the front of the
Female RJ-45 connector as detailed below:

The IPI-4 also utilizes a 6 pin-rigid integrated connector for
connecting the converter to the AXS-100 master controller’s
RS-232 interface as detailed in the table below

Installation and Hookup Details

1. Ensure tht the controller the IPI-4 is to be installed has
been set to position # 1 on the AXS-100 loop.

2. Power-down the AXS-100 controller and connect the
IPI-4 to the serial interface of the controller as shown.

3. To ensure that the controller will provide power to the
IPI-4, place J3’s power source jumper across the two
pins furthest away from the converter.

4. Using a RJ-45 terminated patch cable (not included)
connect the IPI-4 to the LAN/WAN Ethernet network
switch or router.

5. Power-up the AXS-100 controller; the IPI-4 converter will
also power-up and link to the Ethernet network.
