About Electro Industries/GaugeTechAbout Electro Industries/GaugeTech
Electro Industries/GaugeTech was founded in 1973 by Dr. Samuel Kagan. Dr. Kagan’s first innovation,
an affordable, easy-to-use AC power meter, revolutionized the power-monitoring field. In the 1980s Dr.
Kagan and his team at EIG developed a digital multifunction monitor capable of measuring every aspect
of power. EIG further transformed AC power metering and power distribution with the Futura+ device,
which supplies all the functionality of a fault recorder, an event recorder and a data logger in one single
meter. Today, with the Nexus 1250 and a wide variety of dependable solutions, EIG is a leader in the
development and production of power-monitoring products. All EIG products are designed,
manufactured, tested and calibrated at our facility in Westbury, New York.

RS232 Wiring Details
QRS232 communication is capable for a distance up to 50 feet (15.2 m). The Master Port and Slave
Ports 3–16 are 9-pin female RS232 ports. Use standard RS232 extension cables for all RS232
connections.
QThe RS232 Master Port enables the Substation Multiplexor to communicate directly with a computer
or connect to an external modem. The Master Port is DCE or DTE selectable. Set the switch beneath
the port to:
•DTE when using a modem (internal or external).
•DCE when connecting the Substation Multiplexor directly to a computer.

RS485 Wiring Details
QRS485 communication allows multiple devices to communicate on a bus. The Substation
Multiplexor’s Slave Ports 1 and 2 are 2-wire RS485 terminals, capable for a distance of up to 4000
feet (1219 meters).
•Use a shielded, twisted pair cable, AWG 22 (0.33 square mm) or larger.
•Establish point-to-point configurations for each device on a RS485 bus: Connect (+) terminals to
(+) terminals; connect (-) terminals to (-) terminals.
•Protect cables from sources of electrical noise.
•Avoid both “star” and “tee” connections (see diagrams on the following pages). No more than
two cables should be connected at any one point on an RS485 network, whether the connections
are for devices, converters or terminal strips.
•Include all segments when calculating the total cable length of a network. If you are not using an
RS485 repeater, the maximum length for cable connecting all devices is 4000 feet (1219 meters).
•Connect devices using the diagrams on the following pages. A correct connection requires 1/4
watt resistors connected to the (+) and (-) terminals of each device at the end of a straight-line
bus. The line impedance of the cable and the resistor should match. Generally, a 100- or
120-Ohm resistor will work.

Ethernet
Option Configuration
2.1:
Introduction
QThe Ethernet Option gives the user the capability of integrated network connectivity to multiple
devices over Ethernet. This chapter will give the user an overview of how the Ethernet Option
works. Detailed here are the main components of an Ethernet interface and how they are configured.
2.2:
Ethernet Module
QThe Ethernet connection is made with a small module which is embedded in the meter. This small
but powerful module has an RJ-45 Port and the Network Link LED on the front panel tells you when
the unit is connected to the network and is sending and receiving data. When the unit is active, you
actually hear distinct clicking sounds as the Ethernet module does its job.
2.3:
Ethernet Option Setup
QThis chapter covers the required steps to get the Ethernet Interface on-line and working. There is
only one method used to log into the Ethernet Server and set up the IP address:
•Network Port Login: make a Telnet connection to the network port (9999).
QIt is important to consider the following points before logging into and configuring the Ethernet
Interface:
•The Ethernet Interface's IP address must be configured before a network connection is available.
•Only one person at a time may be logged into the network port. This eliminates the possibility
of several people trying to configure the Ethernet Interface simultaneously.
2.4:
Default IP Address
QThe Ethernet Interface ships with a default IP address set to 0.0.0.0, which automatically enables
DHCP within the Ethernet Interface.
Provided a DHCP server exists on the network, it will supply the Ethernet Interface with an IP
address, gateway address and subnet mask when the Ethernet Interface boots up. If no DHCP
server exists, the Ethernet Interface will respond with a diagnostic error: the Network Link LED
blinks five times.

 Electro Industries/GaugeTech Doc #: E113-7-07-101 2-2
2.5:
AutoIP
QAutoIP allows an Ethernet Interface to obtain an address in a network that does not have a DHCP
server. Windows 98 and 2000 also support AutoIP.
AutoIP assigns a random valid address to the Ethernet Interface in the range of 169.254.x.1 to
169.254.x.1 (x can be between 0 and 255). This range of IP addresses is not to be used over the
Internet. If the Ethernet Interface has not been configured manually and cannot find a DHCP server,
it automatically chooses an address from the reserved range. The Ethernet Interface then uses the
Address Resolution Protocol (ARP) to send out a request asking if any node is using that address.
If another node is using the same address, the Ethernet Interface assigns another IP address, reboots
and repeats the sequence.
NOTE: AutoIP-enabled Ethernet Interfaces are constantly looking for DHCP servers. If a DHCP
server becomes available on the network, the AutoIP-enabled Ethernet Interface switches to the
DHCP server-provided address and the unit reboots. If the DHCP server exists but denies the
Ethernet Interface an IP address, the Ethernet Interface does not attach to the network, but waits and
retries.
•AutoIP allows a small network of AutoIP-enabled devices to be set up without any need for a
DHCP server or static IP addresses.
•AutoIP can be disabled be setting the IP address to 0.0.1.0. The 1 in the third octet is the
disabling factor.
2.6:
Setting the IP Address
QThe Ethernet Interface's IP address must be configured before a network connection is available. If
the IP address was not set automatically via DHCP, set it now using a network and the setup
(configuration) menu.
QNETWORK PORT LOGIN
The ARP method is available under UNIX and Windows-based systems. The Ethernet Interface will
set its address from the first directed TCP/IP packet it receives.
QARP ON UNIX
On a Unix host, create an entry in the host's ARP table using the intended IP address and the
hardware address of the Ethernet Interface, which is found on the product label.
arp -s 135.15.173.121.00:20:4a:xx:xx:xx

 Electro Industries/GaugeTech Doc #: E113-7-07-101 2-3
QARP ON WINDOWS
In order for the ARP command to work on Windows, the RP table on the PC must have at least one
IP address defined other than its own. If the ARP table is empty, the command will return an error
message. Type ARP -A at the DOS command prompt to verify that there is at least one entry in the
ARP table.
If the local machine is the only entry, ping another IP address on your network to build a new entry
in the ARP table; the IP address must be a host other than the machine on which you are working.
Once there is at least one additional entry in the ARP table, use the following command to ARP the
IP address to the Ethernet Interface:
QTELNET TO PORT 1
Now open a Telnet connection to Port 1. The connection will fail quickly (3 seconds). But the
Ethernet Interface will temporarily change its IP address to the one designated in this step.
QTELNET TO PORT 9999
Finally, open a Telnet connection to port 9999 and set all required parameters.
NOTE: This IP address is temporary and will revert to the default value when the Ethernet
Interface's power is reset, unless you log into the Ethernet Interface and store the changes
permanently.
2.7:
Networking Configuration
QCertain parameters must be configured before the Ethernet Interface can function on a network. The
Ethernet Interface can be locally or remotely configured using the following procedures:
Use a Telnet connection to configure the unit over the network. The Ethernet Interface's
configuration is stored in nonvolatile memory (NVRam) and is retained without power. The
configuration can be changed at any time. The Ethernet Interface performs a reset after the
configuration has been changed and stored.
As mentioned above, to configure the Ethernet Interface over the network, establish a Telnet
connection to port 9999. From the Windows Start menu, click Run and type the following
command, where x.x.x.x is the IP address and 9999 is the Ethernet Interface's fixed network
arp -s 135.15.173.121 00-20-4a-xx-xx-xx
telnet 135.15.173.121 1
