ES2 Ethernet/SIOX Gateway p 7
When contact is established with the unit, the following configurations may be
checked and changed:
•
IP-address and Subnet mask
for the network where the unit eventually will
be installed. It might be a good idea to perform these changes as the final
ones after the rest of the configurations are handled. Otherwise, an
inadvertent restart of the unit will necessitate a repeated recovery process
as previously described.
•
Default Gateway address
. Used by the ES2 to know where to send
communications with destination addresses outside the network where it is
located. Will typically be the address of the firewall/router.
•
TCP port number
used for SIOX Net communication. This is the port
number that the central should try to connect to when establishing contact
with the ES2. Factory default is 1024 which will usually work fine if the unit
is located on a LAN (Local Area Network) or directly connected to the
Internet. However, if the unit is located on a LAN and access from Internet
is desirable, firewall configurations must be considered as well, as they
normally will prevent connection attempts from the Internet to a LAN. In this
case a 'hole' thru the firewall specifically directed to the ES2 IP-address
must be opened. This is perfectly safe for the LAN and will not represent a
security risk because the ES2 unit does not contain any operating system
that can be manipulated to perform malicious activity on the LAN. Please
contact the network administration to check if this is feasible. However, it is
very important that the firewall configuration will be restored in case the
ES2 unit is permanently removed. Otherwise another equipment occupying
the same IP-address could possibly represent a security hazard.
•
ES2 address
(1 - 63) on the SIOX bus for its virtual SIOX module, thru which
these configurations are carried out. This address can not be used by any
SIOX module connected to the SIOX bus. Factory default address is 63.
•
SIOX bus baud rate.
Available baud rates are 300, 600, 1200, 2400, 4800,
9600 and 19200 baud. Factory default is 4800 baud.
•
SIOX bus current
drive capability 0, 25, 50, 75 or 100 mA. Factory default is
100 mA.
•
Additional SIOX timeout
(0 - 63 ms), used in conjunction with modems or
radio modules where delays inherent in these units must be considered.
Factory default is 0 ms.

Start configuration by writing SIOX baud rate to parameter with the Write Enable
flag set. Refer to
Parameter Description
below for further details. If using the
ES2setup.dff
, simply check the box
EEPROM Write Enable
before changing any
configuration, otherwise it will not be possible to make any changes.
When finished, move the unit to its intended installation point. The new
configurations will take effect after power is applied. Access to the unit may quickly
be tested by sending a 'ping' to it. Use
Visual Setup
or the intended system
application for further testing including access to the SIOX bus to verify that all
connected modules are responding.
