Equinox ESP-2 MI Serial Hub Installation Guide
Displaying or Changing Network Configuration Values
The Network Configuration window displays the ESP-2 MI unit’s IP address, subnet mask and
gateway address. You must configure a nondefault IP address for the ESP-2 MI before the unit
becomes operational.
To display or change network configuration values:
1. Select
Network Con
fi
guration
from the Main Menu.
2. Enter a valid value in the IP Address, Subnet Mask and Gateway Address
fi
elds. 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 an address at or above 248.x.x.x.
3. If you changed any values, click the
Apply
button. The EEPROM con
fi
guration is
modi
fi
ed, but the change does not take effect until the next reboot of the ESP-2 MI. To
reboot, click the
Reboot
button. If the IP address had not been previously set, the unit
reboots automatically.
Displaying or Changing Port Configuration Values
The Port Configuration window displays the interface type for each port. The interface type is
set with jumpers inside the chassis; it cannot be configured in software. If a port is configured for
RS-485, the display indicates the current transfer mode, which can be changed via this window.
To display or change port configuration values:
1. Select
Port Con
fi
guration
from the Main Menu.
2. To see the procedure for changing the jumpers that set the interface type, click the
show
how to change jumpers
link.
3. The
Interface
Type
fi
eld indicates the port’s interface type: RS232, RS422 or RS485.
4. The Transfer Mode (RS485)
fi
eld indicates the current transfer mode if the Interface Type
is RS485. (If the port uses another interface type, this
fi
eld indicates Not Applicable). To
change the transfer mode, select
RTS
or
ADDC
from the Transfer Mode (RS485) listbox.
5. If you changed the transfer mode, click the
Apply
button. The EEPROM con
fi
guration is
modi
fi
ed, but the change does not take effect until the next reboot of the ESP-2 MI. To
reboot, click the
Reboot
button.
