RS-232 serial ports. The optical coupling uses ground and positive voltage from the target devices (TDs) that are attached to the ESP-2 OPTO hub serial ports; there is no metallic connection between the ESP-2 OPTO hub and the TD or between the two TDs.
Installation Guide (this document) 021-0013 Split/Snap-On Ferrite Core The ESP-2 OPTO serial hub model includes an external power supply with an attached PS-to-unit barrel connector. The line cord for the power supply is appropriate to the intended country of operation.
Section 2 - Hardware All connectors, LEDs and buttons are on the front of the ESP-2 OPTO serial hub, as shown in Figure 1. Figure 1: ESP-2 OPTO Serial Hub The POWER connector is located in the lower left corner of the front panel; see Electrical on page 5 for more information.

** DSR and CTS are required for operation, but are not seen by the hub’s CPU. Table 5 lists the pin assignments for the RJ-45 shielded Ethernet connector. The 4- wire power and 8-wire power columns apply to ESP-2 OPTO hubs that use POE; additional information follows the table.
The polarity itself is undefined. In powered network cables with the full CAT 5 cable (4 twisted pairs), power may be provided as described for the two-pair method or over the two spare twisted pairs (polarity undefined), but not both. The ESP-2 OPTO serial hub will automatically accept either method.
Make the power connection for the hub. If the hub’s power will be supplied through the external power supply, plug the barrel connector of the PS into the front of the ESP-2 hub, then attach the line cord connector to an appropriate power source.
A split/snap-on ferrite core (part number 021-0013) is included in the shipment. It is recommended that this be used to further suppress electromagnetic interference (EMI) for ESP-2 POE hubs by installing the ferrite core on the LAN (Ethernet) cable. Use Figure 2 for reference.
Be careful to avoid crimping or squeezing any part of the cable. Use of the ferrite core is the responsibility of the user. The ESP-2 OPTO hub generates, uses and may radiate radio frequency energy and, if not used in accordance with these instructions, may cause harmful interference to radio communications.
Section 3 - Serial Port Connection Methods and Attributes There are several methods a remote device may use to access a serial port on an ESP-2 OPTO hub and then transmit/receive data from that port: • Serial port redirection - see page 9 •...
For example, a value of 100 indicates that once serial data is received, the Serial ESP-2 hub will buffer the data until 1 second (100 hundredths of a second) has buffering elapsed, at which time all data will be sent.
For example, a value of 100 indicates that once serial data is received, the Serial ESP-2 hub will buffer the data until 1 second (100 hundredths of a second) has buffering elapsed, at which time all data will be sent.
Valid values are 0-65535 hundredths of a second. For example, a value of 100 indicates that once serial data is received, the ESP-2 hub will buffer the data until 1 second (100 hundredths of a second) has Serial buffering elapsed, at which time all data will be sent.
For example, a value of 100 indicates that once serial data is received, the Serial ESP-2 hub will buffer the data until 1 second (100 hundredths of a second) has buffering elapsed, at which time all data will be sent.

4.1 Accessing the Web Interface The ESP-2 web interface may be accessed using any standard web browser with the IP address of the hub as the URL. For example, if an ESP-2 serial hub has an IP address of 192.168.0.5, entering the URL will connect to the web interface.
When using the web interface, the password is encrypted by the browser when it is sent to the interface. If you reinitialize the ESP-2 serial hub, the password is lost. You will be required to create a password the next time you access the web interface or the configuration utility.
To reboot, click the Reboot button. If the IP address had not been previously set (or the hub has been reinitialized), the ESP-2 hub reboots automatically. 4.5 Displaying or Changing Port Attributes and Connection Methods The Port 1 Configuration display includes the serial port attributes and connection methods for port 1.
Click the Apply button. The update process may take up to 30 seconds to complete. After the update completes, status will be displayed.

Click the Apply button. The update process may take up to 30 seconds to complete. After the update completes, status will be displayed. The new FLASH image will be used after the ESP-2 serial hub reboots. 4.8 Displaying or Changing Configurable Features The Configurable Features display includes the current settings of the features described in Table 14.

The Port Redirection Connections section includes the information described in Table 18 about the servers that are connected to each of the ESP-2 serial ports. This display is meaningful only when a serial port is being accessed using the serial redirection connection method.
30 seconds, direct your browser to the predefined IP address (192.1.1.1). You may also reinitialize the ESP-2 serial hub using the configuration utility (see Reinitializing the Hub on page 30) or the INIT button on the front panel (see Reinitializing on page 8).
The configuration utility may be accessed three ways: with Telnet, by serial connection to port 1 when the ESP-2 serial hub has no configured IP address or by serial connection to the port(s) that have the configuration utility connection method enabled.
(usually ). If the serial configuration utility connection method is used to access the utility and an inactivity time-out is enabled, a session will end if the inactivity period is reached. Equinox ESP-2 OPTO Serial Hub Installation and User Guide...
If you reinitialize the ESP-2 serial hub, the password is lost; you will be required to create a password the next time you access the configuration utility or the web interface.

The Configurable Features display includes the current settings of the features described in Table 14 on page 19. When the ESP-2 serial hub is reinitialized, all configurable features are restored to their default settings. To view or change configurable features: From the Top Menu, enter to select Server Configuration.
From the Server Configuration menu, enter to select Reboot. You may also reboot the ESP-2 serial hub using the web interface (see Rebooting the Hub on page 22) or the RESET button on the front panel (see Resetting on page 8).
The Port Redirection Connections section includes the information described in Table 18 on page 22 about the servers that are connected to each of the ESP-2 serial ports. This display is meaningful only when a serial port is being accessed using the serial redirection connection method.
A configuration file may also be downloaded using the web interface or the configuration utility. A file-based reconfiguration of an ESP-2 hub may also be initiated using a third party SNMP agent. An SNMP MIB is available through Equinox Technical Support.
In commands that require a port number, you may specify instead of a port number if you wish the command to be applied to both ESP-2 MI hub serial ports. The command syntax in this manual uses the following conventions: •...
[PARITY=NONE|EVEN|ODD|MARK|SPACE] [STOP=1|2] [FLOW=NONE|XON/XOFF] 6.5 Network Command The Network command specifies the ESP-2 hub address information. NETWORK IP=<ip> MASK=<mask> GATEWAY=<gateway> The addresses must be entered in standard IP dot notation. The gateway address must be in the same subnet as the IP address. You cannot set the IP address to: a Class A address of 0.0.x.x, a loopback address of 127.x.x.x, the default value of 192.1.1.1 or...
When used from a BootP or SNMP server, no user interaction is required when a configuration file is downloaded. Specify the configuration file as the “bootfile” option on the server. (To use a DHCP server, the ESP-2 hub must have an infinite lease on its assigned IP address.) When using the web interface, follow the instructions in Downloading a Configuration File on page 19.
