8 Port COE-8I & COE-8O
Contact Closure Over Ethernet
Overview
COE-8 is a system for transporting switch closure information over a TCP/IP network. The COE-8
consists of two devices, and Transmitter Unit (COE-8I) and a Receiver Unit (COE-8O). The COE-8I
provides 8 inputs for switch contacts, relay closures or DC Voltage. Upon a change of state for any
channel, it will transmit a message to one or more (up to 32) COE-8O units. The COE-8O has eight
relays that will mirror the status of the eight inputs of the COE-8I. Each unit can be monitored and
configured from a Web Browser.

Hardware Installation
Inputs (COE-8I)
Connect the inputs to the COE-8I using the screw terminals on the printed circuit card, as illustrated. Inputs
can be either dry relay or switch contacts, or a +VDC voltage (3 to 30 V), referenced to a common ground.
Status Dry Relay DC Voltage
Open Open >3VDC
Closed Closed <=0VDC
Input Specification Dry Contact (common ground) or Wet ±30VDC Max
Relays (COE-8O)
Connect the inputs to the COE-8I using the screw terminals on the printed circuit card, as illustrated.
Relays are Form A. Relay Specifications
Rating (resistive) 0.5 A 120 VAC or 1 A 24 VDC
Maximum Carrying Current 2 A
Maximum Switching Power 60 AV, 24 W
Maximum Switching Voltage 120 VAC/60 VDC
Maximum Switching Current 1A
Life Expectancy: 5 Million Operations Mechanical 100K Operations at rated load
Network
Connect the network to the connector provided. A yellow LED indicates a successful connection to the
network, a green LED data activity.
Power
Apply power only when the cover is secured onto the COE-8. Use only the wall mounted power supply
provided.

WEB Page Access
The web pages provide status information on the inputs and outputs of the COE-8, as well as provide
configuration for the unit. Open a browser to the default or current IP address of the unit.
Enter the default username and password:
Factory Defaults:
IP Address 192.168.1.254
Username admin
Password admin
The unit will display the current status of each of the channels and provide buttons for Refresh, Setup
and Logout.

Configuration
Setting I/P Address
The COE-8 units provide three methods for setting the IP Address
1) Static IP via the Web Page Setup
2) DHCP
3) ARP/Ping
WEB Page
Login to the COE-8 and access the Setup pages by clicking on the Setup button from the home page.
Click on the IP button to bring up the IP Settings page:
Select Static Mode from the radio buttons and fill in the IP Address, Subnet Mask and Gateway as
provided by your network administrator. Click Apply to save the changes. You will then be prompted
to reboot the COE-8. Click on the Reboot button. The COE-8 will reboot and the new IP address will
be ready to be accessed.
DHCP
Selecting DHCP from the IP Setup page allows a DHCP server to provide IP address information to
the COE-8. Click Apply and then Reboot when prompted. The COE-8 will reboot and will have to be
accessed with the IP address assigned by the DHCP server. If no IP address is assigned by a DHCP
server, the original IP address will be retained.

ARP/Ping
Select ARP/Ping radio button. Click Apply and then Reboot when prompted. Follow the steps below.
It is recommended that after a successful setting of the IP address using this method, that the Mode
be changed back to Static. This will prevent malicious programs from altering the IP address.
To set the IP address, the hardware (MAC) address must be known. This address is located on a
label on the bottom of the unit. The syntax for the MAC address is: nn-nn-nn-nn-nn-nn. To set the IP
address using ARP, connect the 10Base-T connection to your local ethernet network and apply power
to the unit. The computer used to set the IP address must be on the same subnet as the COE-8. ARP
does not work across routed or switched networks.
Windows® (98 and later)
1. Open a Command Prompt window.
2. Type the following command:
arp -s <IP Address> <MAC Address>
Where <IP Address> is the desired IP address for the COE-8 and the <MAC address> is the MAC
Address of the COE-8. The MAC Address of the COE-8 is located on the COE-8’s serial number
label. Windows 95 users see note below.
3. Ping the device to program the IP address by typing the following:
ping <IP Address>
If the ping command returns “host not responding” 4 times then the address has not been programmed
properly, or the IP Address is incorrect. In either case redo step 2. If the problem persists contact
the Tech Support Hot Line.
4. Delete the entry from the ARP cache by typing:
arp -d <IP Address>
5. Ping the device again (step 3) to confirm that the address has been programmed properly
Unix, Linux, other
Consult your systems administrator for information on setting an IP Address using ARP.
The unit should be pinged after the IP Address has been set to confirm proper operation.

Setup
The Setup button from the Home page provides access to all the configuration of the COE-8. The
Setup area is divided into several pages:
Device Page:
Basic setup of the COE-8, IP address and TCP/IP settings
Name Assign a name up to 20 characters to help identify the COE-8
IP Address Set the IP Address manually in the Static Mode (see below)
IP Modes Set the method to configure the IP address. See section above for details.
§ Static: Manually entered IP address information
§ DHCP: IP address obtained upon power up from DHCP server.
§ ARP-Ping: IP address set from another computer
Port Settings The IP Setup page also allows for changing of the port assignment for both the Control
communication and web page access. Black Box recommends changing the Web port for units that
will be connected to the Internet. This will minimize the number of hacker attacks that the COE-8 will
be subject to.
The Control Port for both the COE-8I and all COE-8Os that receive status from it must be set the same.
If a port other than the default Port 80 is used for web browser access, that port must specifically be
used in the URL when accessing the COE-8. For example, if the Web Port is changed to 9090 then
the URL for the unit would be http://192.168.1.254:9090
Receivers (COE-8I Only)
Transmission Frequency 0 to 9999 seconds
This sets the frequency that the COE-8I transmits its status to the receivers. When set to 0,
transmission will only occur upon change of status.
Receiver IP Address Set up to 32 IP addresses of the COE-8O units that will have input
status information set to them.
Inputs (COE-8I Only)
The COE-8 I can send individual input status to multiple COE-8O receivers, or other IP address. This
page provides for selecting which output of the COE-8Os will be operated by each input of the COE-8I.
Select the Input from the drop down box, then configure the Name for that input, along with the
channel of each COE-8O unit to receive the status. Use Output 0 if no output of a given COE-8O is to
be used for that channel. Configure each of the 8 inputs as necessary.

SNMP
The COE-8 can be monitored and configured via SNMP managers.
Download the MIB at ftp://ftp.blackbox.com/lan/
Enter the IP addresses of up to 4 SNMP managers. Enable or Disable SNMP with the checkbox provided.
Traps can be sent every time there is a change of state on any COE-8 channel. Check the box provided to
enable this. If both the COE-8I and COE-8O are configured to send traps, two messages will be received by
each SNMP manager for each event.
Passwords
Two username and password sets allow for two types of users:
User Type Default Username / Password Access
Administrator admin / admin Full view and setup
General User user / user View status only
Click Apply to save the new usernames and passwords.
