Replacing Software
Electronic Download Method
In order to help upgrade to the latest features available, we are pleased to offer software
updates over the internet. This process downloads the new software into a secondary bank of
your TWOx12’s memory, leaving the original software intact. You then have the option of
running the new software or the old software. Once you have verified that the new software is
more suitable to your needs, you may make it your default.
If you do not have the proper connectivity to handle the electronic download method, contact
Technical Support to request a flash SIMM be shipped with the desired software. Then follow
the steps in the next section to replace the SIMM module. This method is not as convenient as
it requires opening the unit.
To upgrade your unit using the electronic download method you will need the following:
• Ethernet connection to the TWOx12 from a LAN connected to the internet.
• The Remote Cntrl selection of the TCP/IP Setup menu (accessed from System menu)
must be set to All or Trusted.
• The TWOx12 must be programmed with the following information (see Section 7.3.3
for details):
IP Addr
This is the IP address for this TWOx12. As with any computer on an IP network the
TWOx12 must have an IP address before it can be used over the network.
Subnet
This is your subnet mask. The subnet mask is to determine the size of your “local”
network. All packets addressed to a destination outside this “local” area are sent to
the gateway node entered in the next selection.
Gateway
This is the IP address of a gateway router connecting you to the internet.
DNS IP
This is the IP address of the DNS (Domain Name Server) you will be using.
The complete software download process is explained in section 7.3.3.
Manual Replacement Method
The system’s software is contained within a flash memory SIMM module, similar in size and
form to those used for PC memory. If you need to change this module, follow the procedure
below:
1) Power the TWOx12 off and remove the AC mains power connector.
2) Remove top cover. Remove all 7 Philips-head screws from the top cover.
3) Remove right old software SIMM
• Turn the right side of the unit towards you (the power supply will be away from you).
