Installing the Configuration Program
The following steps provide information on how to install the Configuration
Program onto your computer. The configuration program is used to create a
configuration file.
1. The Configuration program is available on the JBM website
www.jbmelectronics.com. This program is a self-extracting file.
2. Using the root drive of a DOS compatible PC, execute the zip file that
comes on this CDROM under the ‘Programs’ section. Contact JBM
Electronics customer support to determine if there is an upgrade for the
application.
Important Information: Unless otherwise instructed, use only the default
path and filenames at the root directory of the PC that will be used to
develope and load configurations onto the Gateway Unit. In order to retain
the integrity of all JBM programs, and ensure the proper functioning of the
Gateway Unit(s), default folders and filenames will automatically be
extracted from the configuration program executable as JBMGATEW.

Type SETUP at the \JBMGATEW prompt to initialize the self-extraction of
the sub-directories and associated files.
3. Enter the default User ID and Password, gateway, to enter the
configuration program. This default password must be entered in
lowercase
4. You can find additional information and support on our website:
www.jbmelectronics.com
Gathering Information
Determine what protocols will be used in this config. Select the corresponding
worksheet located on the software CD or at www.jbmelectronics.com. Use this
worksheet as an information-gathering tool. Complete and accurate information
on these sheets is essential to a successful installation.
For the IP interface(s) configuration you will need to have an IP address, default
gateway, and subnet mask assigned by your network staff for the new unit.

Using the Gwlnx Configuration Utility
The JBM Electronics Gateways are used to convert Legacy serial data to IP
protocols. Because of the wide range of parameters that can be selected, JBM
has prepared a walk through to illustrate how the Gateway can be configured.
JBM supplies an offline configuration program that is used to build the
configuration file. The file is then transferred to the Gateway where it is used to
customize the unit to the specific environment.
The following information provides the proper steps and examples of how to build
a configuration converting Bisync 3270 (Host) to TCP (Client) using the
Configuration Utility.
Note: All setup worksheets should be filled out accordingly before configuring
the Gateway!!
You must navigate through all RED FIELDS!!!
At the login screen the default user logon ID and password are “gateway” (please
note that these fields are case sensitive). Press <Enter> after you have
completed these fields. For security purposes the user ID and password can be
changed in the ‘Define Remote Access Information’ section.

You are now at the ‘Main Menu’ screen. Tab the cursor down and select ‘Unit
Configuration’ by pressing <Enter>.
When the selection box appears, select ‘New’ by pressing <Enter> on the field.
This will allow you to begin creating a new configuration to load into the Gateway.

Assign a unique name to describe your configuration. Once you have entered a
name press <Enter> to advance to the next screen.
At this screen select the unit model you will be configuring by tabbing the cursor
to the appropriate field and pressing <Enter>. For example, if you are
configuring a G1000, tab your cursor to ‘Gateway 1000’ and press <Enter>.

At the ‘Unit Parameters’ screen, highlight the ‘Define Remote Access Information’
field and press <Enter>. This will allow you to customize the LAN properties of
the Gateway.
Note: The Define Remote Access Information Field configures the LAN
properties for the Gateway 50 through 80 units only. The Gateway 100 through
900 series and the Gateway 1000’s LAN information is configured at the Linux
prompt by issuing the command niccfg eth0. Once the command has been
issued, you will be prompted to enter the correct IP information. If you are using a
G100-G1000 series unit, simply navigate into the Define Remote Access screen
and then press F12 to return to the Unit Paramters screen leaving the fields on
the Remote Access Information screen blank.

Once returned to the ‘Unit Parameters’ screen, tab down to the ‘Define Port IDs’
field and press <Enter>. This allows you to customize the characteristics
performed by the port controllers of the Gateway.
Assign an identity to each port that you will be configuring. Complete the name
for the port and press <Enter> to continue to the ‘Port Parameters’ screen.

Tab down to the ‘Protocol’ field and press <Enter> to choose the appropriate
protocol for the port controller.
Choose from a list of protocols that are supported by the Gateway. Use the
arrow keys to navigate to the appropriate protocol and press <Enter>. For this
example, select the Bisync 3270 (Host) protocol by highlighting its name and
pressing <Enter> on Bisync 3270 (Host).
The selected protocol determines how the Gateway port will behave. For
example, when Bisync 3270 (Host) is selected, the Gateway port will poll
attached Bisync 3270 protocol terminals.

Complete the ‘Bisync 3270 (Host)’ Setup Worksheet that has been provided on
this CD-ROM before modifying any parameters of the Gateway!
*REMINDER, you must navigate through all RED FIELDS.
The CU Address specifies the address used by the host to poll a specific device.

The Device Address is assigned to a specific device that is to be polled by the
host.
After modifying all the parameters to fit your environment, press <F12> to save
your progress and return to the ‘Port Parameters’ screen.

Tab down and highlight the ‘Define Hardware Information’ field and press
<Enter>.
At this screen enter the appropriate hardware address and press <Enter>, this
number reflects the labeled port number on the Gateway faceplate. After you
have entered this information press <F12> to save your progress and return to
the ‘List of Port IDs’ screen where you will choose the next Port ID and Protocol
for the remote side of your configuration
Note: For ports labeled ttyS* you need to add “1” to the ttyS* numbers for COM
port mapping.

Assign a name for the remote port that will be routed to the previously configured
port controller and press <Enter>.
Choose from a list of protocols that the Gateway will support by navigating down
to the appropriate protocol and pressing <Enter>. For example, select TCP
(Client) protocol by tabbing down and pressing <Enter> on TCP (Client).

Tab the cursor down to ‘Edit Current Port Configuration’ and press <Enter>.
Complete the ‘TCP (Client)’ Setup Worksheet from our website before modifying any
parameters of the Gateway!
*REMINDER, you must navigate through all RED FIELDS.

After you have modified all the parameters to fit your environment, press <F12>
to save your progress and return to the ‘Port Parameters’ screen.
Tab the cursor down to ‘Define Routing Table’ and press <Enter>. This option
allows you to route data from one port to another.

The ‘List of Port IDs’ screen will list the different Port IDs that you have assigned
for the Gateway. In this example we will be routing the ‘Bisync 3270 (Host)’ port
to the ‘TCP (Client)’ port. The ports must be routed “back to back.”. Start by
highlighting a Port ID and pressing <Enter>.
Confirm the sub address that you will be routing by highlighting the selection and
pressing <Enter>.
Note: A route is a data source not destination.

Gateway C102/C112 Reference Guide Page 18

Select the route for the specific Port ID. Highlight TCP (Client) and press
<Enter>. This step is an example of the Bisync port receiving data from the TCP
(Client) port.
This screen will verify the source that the Bisync 3270 (Host) port will be
receiving data from. Verify the address and press <F12> to save your progress
and return to the ‘List of Port IDs’ screen.

Gateway C102/C112 Reference Guide Page 19

Select the remote Port ID you are routing and repeat the same steps you just
performed for the ‘Bisync 3270 (Host)’ Port ID.
Confirm the sub address by highlighting the selection and pressing <Enter>.

Gateway C102/C112 Reference Guide Page 20

Highlight the route for the specific Port ID and press <Enter>. Remember that
you must route the IDs “back to back.” For example, route the ‘TCP (Client)’ port
with the ‘Bisync 3270 (Host)’ port.
Verify the destination that the ‘TCP (Client)’ port will receive data from. If
configuring numerous port IDs and sub addresses route them accordingly based
on the steps provided above. After routing all sub-addresses within the
configuration, press <F12> to save your progress and return to the ‘Configuration
Menu’ screen.
