Section 1 - Hardware
The Equinox SuperSerial Technology (ST) Ethernet Serial Provider 8-port
Multi-Interface (ESP-8 MI) Serial Hub can be installed in a local or remote
LAN to provide access for widely distributed RS-232, RS-422 or RS-485
serial devices. The ESP-8 MI is supported under Windows 2000, Windows
NT 4.0, Windows NT 3.51, OpenServer 5.0.5a or higher, UnixWare 7.0.1a
or higher, Linux and AIX 4.3 and 5.1.
The ESP can be managed using EquiView Plus, the Equinox premier serial
port management software, running on any Microsoft Windows host, or
espdiag and espcfg for OpenServer, UnixWare, Linux or AIX.
The ESP-8 MI kit contains the items listed in Table 1.

Item Description
POWER The POWER LED is lit when the ESP is connected to a
power source
ONLINE The ONLINE LED is lit (not blinking) when the ESP self-test
and initialization procedures have completed successfully
LINK The LINK LED is lit when the ESP recognizes that is has a
connection to the network
TRAFFIC The TRAFFIC LED blinks when there is network trafc
100MBps The 100MBps LED is lit when the ESP is connected to a
100 Mbps LAN
RESET Pushing the RESET button reboots the ESP; for more
information, see Section 1.4
INIT Pushing the INIT button restores the ESP to factory defaults;
for more information, see Section 1.4

NOTE : It is important that unused pins (labeled N/C) should not have wires
attached to them. Floating wires could cause unbalanced noise, shor ten overall
distances and degrade performance.
3 Equinox ESP Multi-Interface Serial Hub Product Installation Guide
1.1 Hardware Installation
1. The MAC address is printed on a label afxed to the back of the unit
above the LAN connector socket (see Figure 2). This address will be
used as a Unit ID to distinguish different ESP units on the network.
Record the MAC address.
00 - 80 - 7D - _____ - _____ - _____
2. Attach a 10BaseT or 100BaseT LAN interface cable to the LAN
connector on the back of the ESP. A CAT 5 cable is required for
100BaseT operation.
3. Power on the ESP by connecting the power cable to a power source.
WARNING: The power outlet should be installed near the equipment and
should be easily accessible.
4. Install the ESP driver using the instructions in Section 2 for your
target operating system.
5. Install or upgrade to EquiView Plus version 5.1 or higher from the
Equinox SuperSerial Software CD. EquiView Plus will help manage
ESP units on various networks.
If the ESP fails to boot ...
The ESP is very robust and there are few errors that can prevent the unit
from correctly initializing and going online. However, if an error does
occur, the ONLINE LED will blink a repeating pattern with discernible
pauses. Count the number of blinks between pauses and make a note of
this value. When you contact Technical Support, this information will help
determine the cause of the initialization failure.
