1Product overview
The GYDA System Controller is an advanced control and monitoring card for
the flashlink®system. The card occupies a single slot in a flashlink®frame and
can control and monitor up to 8 flashlink frames, each with up to 10 flashlink
modules, a total of 79 modules.
The controller connects to a standard 10BaseT twisted pair Ethernet with
TCP/IP protocol. The user uses a standard web browser to configure and
monitor the flashlink system (i.e. no special software
is needed on the PC, any PC with a web browser will do). All relevant manuals
are also available via the web interface in adobe PDF format.
For users with large heterogeneous systems, the controller supports SNMP
(Simple Network Management Protocol), a generic TCP/IP based protocol for
management of a wide variety of devices. The controller software is located on
a removable compact flash card (the same card type frequently used on
digital cam-eras), and can be easily upgraded by copying new files to the flash
card. New software can be downloaded from our web site.
The controller module has four GPI inputs and a GPI open collector output.
The output is a “catch all” error output. The inputs are general purpose,
intended for monitoring external equipment like battery backup systems,
climate control and power supplies. Note that all flashlink®power supplies
have GPI outputs, which can be used as inputs to the controller.

GYDA-SC Rev. 4
3Configuration
Each card has a unique identifier called card position, which is assigned
(trough hardware pinning) automatically when a card is inserted into a frame.
The card positions are numbered from 1 to 10 from a user point of view. From
a protocol (or software) point of view, the cards are addressed 0-9, but the
user should always see positions 1-10 in menus, etc.
Each frame (if you use more than one) should have a unique frame id,
numbered 0-7 (user and protocol/software wise).
3.1 Address setting on each sub-rack
Figure 2 shows the power connections of the frame as well as the RS-422
connections and the DIP-switches for address setting of the frame.
Figure 2: Connector module for the power supply.
Each sub-rack can be assigned an address through the DIP-switches on the
rear. Maximum 8 sub-rack addresses are available.
This address setting only applies when the sub-rack is used in combination
with a GYDA-SC Rack System Controller.
If you have more than 8 sub-racks together, you need several GYDA-SC Rack
System Controller cards.
In order to ensure proper operation of the system, it is
important that no sub-racks controlled by the same
GYDA-SC Rack System Controller card have the same
address set.
Reset the sub-rack after reconfiguring the sub-rack system,
by turning the power off and on again.
Remember to terminate the last frame with a 110Ωresistor.
Note!

4Connections
4.1 Connecting several sub-racks together
Several sub-racks can be connected to each other through the RS-422 ports
on the rear of each sub-rack.
One GYDA-SC controller can control maximum 8 sub-racks.
You start with the sub-rack containing the GYDA-SC Rack System Controller,
and use 1 RS-422 port to loop through to the next.
The last sub-rack connected must be terminated with 110Ωin order to ensure
proper operation. The other port of the rack containing the GYDA-SC
controller must be left open, and cannot be connected to other sub-racks.
Figure 5 shows an example of how to connect 8 sub-racks together as seen
from the rear end. By using the RS-422 interface at the GYDA-SC controller
card, we control 8 sub-racks via one RS-422 bus.
Figure 5: Control of 8 sub-racks with GYDA-SC.
The 110Ωtermination plug used is a standard RJ45 plug with the following
internal wiring:
1236
Figure 6: RS-422 termination.
In the figure above, Pin 1 is connected to Pin 2 with a 110Ωresistor, and Pin 3
is connected to Pin 6 with a 110Ωresistor.

4.2 GPI connections
The output can be used for wiring up alarms for third party control systems.
The GPI outputs are open collector outputs, sinking to ground when an alarm
is triggered. The GPI connector is shown in figure 7.
The GPI output will be active, if one or more alarms are active in the system.
This means that each GYDA System Controller can monitor the status of e.g. 4
different power supplies. To monitor more than 4 external devices, these must
be hardwired together as AND logic.

5Connecting GYDA to your local area network
Follow this guide to quickly install your GYDA controller to an Ethernet
network.
This quick guide assumes that you already have a computer connected to your
LAN and have TCP/IP running on that computer. If you are unfamiliar with
TCP/IP, it could be a good help to have assistance from your system administrator
while doing this.
5.1 Ethernet connection
The GYDA System Controller has a 10Base-T connection on RJ-45. This can be
connected to your local area network devices like a switch or a hub with
unshielded twisted pair cable of type cat 3 or higher.
To access the GYDA System Controller directly from a laptop PC you can use a
crossover cable.
5.2 Assigning an IP address to GYDA
Step 1:
Get an IP address for your unit. Your network administrator normally assigns
this. Remember that the IP address must be unique on your LAN. If you use
the same IP address as another device or machine on your network, you will
cause network problems for you and other users of the LAN. Please make sure
that you use a unique IP address.
Write down the IP address here:
The IP Address for the controller is:
Step 2:
Write down the controller MAC address (also called an "Ethernet address" or a
"hardware address") on the controller card. This is printed below the Compact
Flash Card on the GYDA controller, or on a printed sticker on the backside of
the controller.
A typical MAC address looks like: "00-01-C0-00-21-35"
A MAC address can contain the numbers (0-9) and the letters A to F.
Note that the MAC Address can never contain the letter O, only the number 0
(zero).
Write down the MAC address here:
The MAC Address for the controller is:
12

GYDA-SC Rev. 4
Step 3:
Find a machine on the network that has Windows NT/95/98/W2K/XP or Unix
(Linux) installed. Start a command shell (DOS prompt) and type in (You may
have to be logged in as "Administrator" on your machine if you run Windows
NT, or "root" on Unix):
arp -s <ip_address> <mac_address> [ENTER]
ping -t <ip_address> [ENTER] (the -t option is only used on Windows)
The mac address separator is '-' (hyphen) under Windows and ':' (colon) under
Unix or Linux.
Let the ping command run…
Example, setting IP address to 10.10.10.199
arp -s 10.10.10.199 00-01-C0-00-21-35
ping -t 10.10.10.199
Step 4:
Connect the controller to the network, and turn the unit on. Wait until the
unit has booted (typ. 30 sec).
You should see that the ping command is starting to get replies, similar to the
sequence below:
64 bytes from 10.10.10.199: icmp_seq=0 ttl=255 time=1.205 msec
64 bytes from 10.10.10.199: icmp_seq=1 ttl=255 time=1.048 msec
...
Press Ctrl-C to stop the ping command.
Step 5:
Start your web browser. Type in the URL: http://ip_address/ (e.g.
http://10.10.10.199/), and you should see the GYDA start page.
-Go to the CONFIG tab, press IP address setup and log in as described in
Chapter 7.4. When you are granted access, select “STATIC IP ADDRESS”,
and set the IP address and other relevant parameters and press "Change IP
settings".
-Go to the CONFIG tab again, press General setup and press “Restart
system”. You will loose the connection with the controller for ~60 sec,
while the unit is restarting with the static IP settings.
“Step 6”:
Congratulations, you have now successfully connected the GYDA controller to
your LAN.

GYDA-SC Rev. 4
6GYDA Status Monitoring and external alarms
6.1 GPI I/O
The output can be used for wiring up alarms for third party control systems.
The GPI outputs are open collector outputs, sinking to ground when an alarm
is triggered. The GPI connector is described in Chapter 4.2.1.
The GPI output will be active, if one or more alarms are active in the system.
This means that each GYDA System Controller can monitor the status of e.g. 4
different power supplies. To monitor more than 4 external devices, these must
be hardwired together as AND logic.
6.2 Front Panel - Module Status Monitoring
The status of the module can be easily monitored visually by the LEDs at the
front of the module. The LEDs are visible through the front panel as shown in
the figure hereunder.
Figure 8: The LEDs of GYDA-SC (text not printed on the front panel)
The GYDA-SC has 4 LEDs each showing a status corresponding to the GPI
pinning. The position of the different LEDs is shown in the figure above.

7GYDA web interface
7.1 General
GYDA System Controller can control and monitor up to 79 modules, in a total
of 8 frames. Each frame must be configured with a unique frame address, set
by DIP switches at the rear of the frame, as described in Chapter 3.1 of this
manual and in the user manual for the flashlink®frame, FR-2RU-10-2.
Interconnection of several frames is also described in the user manual for the
frame itself, as well as in Chapter 4.1 of this manual.
There are six different + one optional views in the GYDA System Controller
web interface. Each has its own menu-tab at the top, and will be highlighted
when selected.
-HOME (Optional, see Chapter 7.3)
-SYSTEM (An overview of the system connected to GYDA)
-ALARMS (All alarms within the system.)
-LOG (All events after power up of the GYDA System Controller)
-CONFIG (TCP/IP and SNMP Configuration Settings)
-MANUALS (All user manuals in PDF-format)
-ABOUT
Figure 9: The menu-tabs of the GYDA web interface.
GYDA-SC has two different pages for each module (found under the
“SYSTEM” tab).
Module Information Page Module Configuration Page Open user manual
Figure 10: The icons for the different views in the "System" menu.
Each of the different modules in the modular flashlink®range has a dedicated
icon, which will appear in the corresponding position of the frame.
The default user name and password for access to the sub menus under the
CONFIG tab is described in Chapter 7.4.

7.2 GYDA web interface – screen navigation
The web interface with the information view of the GYDA System Controller is
shown in figure 11. To the left we see the detection and indication of the 1-8
frames that are connected to the system. In this case frame 0 is selected of the
3 frames that are connected to GYDA. On the frame itself, we see the
indication of the active card as a grey frame on the red front. By clicking the
different positions or icons of the frame, the different card modules can be
controlled.
Frame
inicator Card indicator
Figure 11: Information view of the GYDA System Controller.
Figure 12: The icon for the GYDA System Controller.
As shown in figure 11, we can get a summary of the alarms in the system.
Each alarm can be in one of three different states:
-Active (Red colour). An alarm is present in the system, and is not
acknowledged.
-Acknowledged (Yellow colour). A present alarm that has been
acknowledged.
The alarm will disappear from the list as soon as the condition that set the
alarm no longer exists.
-Restored (Green colour). The condition that set the alarm does no longer
exist. The alarm must be acknowledged in order to disappear from the list.
The status for the GPI inputs of the GYDA System Controller is shown below
the alarm list. The status can be either active (triggered by an external device)
or inactive.
16

GYDA-SC Rev. 4
The GPI output can also be in one of two states. The GPI output is a catch all
GPI output. If one or more alarms are active in the system, the GPI output will
be active, whereas if all alarms are either acknowledged, restored or there are
no alarms in the system, it will be inactive.
The CONFIG screen of the GYDA System Controller has settings for how
GYDA shall work.
-Search for new cards
Useful if the system configuration changes frequently.
This setting means that all 79 possible addresses are polled each time in
order to search for new modules.
-Collect info from known cards
Default setting, this setting is useful if the system doesn't change
frequently.
This setting will poll the status of known cards and one new empty slot at
a time. New cards will be detected at a rate determined by the number of
cards in the system, the more empty slots the longer it will take to detect
new modules. On the other hand, all cards are now polled once per
second so changes on the known modules will be reported much faster
than before.
Single scan of empty slots
Will scan all empty slots for new modules. Setting is only available when
the 'Collect info from known cards' is chosen. Useful to speed up the
detection of new modules. Will not affect the scanning mode of GYDA.
7.3 Home tab
Generic webserver for static html can now be enabled from the CONFIG
page, under "General setup". This will change the graphics on the tab-menu
(might need a forced reload of the browser to see it properly). This homepage
can also be set as start page if this is needed.
Figure 13. Home tab configuration
Figure 14. Home tab enabled
The static pages can be put on the CF (Compact flash) card in the directory
called "home". To access the “home” directory, you need to remove the
flashcard from the GYDA module and put into a PCMCIA/USB adapter for CF.
The file structure of the CF is shown in figure 15.
17
Make sure that you don’t modify files outside the “home”
directory; this may STOP GYDA from working.
Note!

GYDA-SC Rev. 4
Figure 15. File structure of the CF
Make sure URLs are relative, or reference files on other WEB
servers. References to c:\\xxxxx or similar will not work.
Note!
7.4 Password protection
The built-in password protection uses the htpasswd mechanism of the Apache
web-server. In the default setup, GYDA allows anonymous / open access to
the card information Two extra levels of protection (observer and operator)
can be enabled for situations where anonymous access to the system-, alarm-
and log tabs are not wanted.
To enable “Strict password protection”, go to the CONFIG tab, select User
and access administration.
Figure 16. Default setup of User and access administration.
18

GYDA-SC Rev. 4
The three access levels are defined as follows:
-Observer
Read only account, can’t acknowledge alarms and re-configure modules.
-Operator
Has access to acknowledging alarms and re-configuring modules.
-Administrator
Access to the CONFIG tab.
The levels are not inclusive, so a normal user account needs both observer and
operator access. The default admin account does not have observer and
operator access for security reasons. There is no limit to the number of users.
In factory setting, all passwords are: password with user
names as shown in figure 16.
Note!
Remember to change the admin password to prevent abuse
of GYDA.
Note!
7.5 Icon and labels for passive modules.
Passive optical modules like: WDM, CWDM, DWM and WOC don’t contain
any microcontroller which makes them able to communicate with GYDA.
However, through GYDA it’s possible to assign a graphical icon and a label for
the module to make it visible in the GYDA user interface. The procedure is as
follows:
-Click on the slot were the passive optical device is installed.
-Press the “Tool”button below the frame.
-Select the type of module from the “Card type”pull down menu.
-If needed give the module a name in the “Card label”box.
-Press Apply.
The graphical icon and the name of the module will appear when
returning to the SYSTEM tab, as shown in figure 17.
