RollTrack

The RollTrack settings allow information to be sent, by means of the RollCall
network, to other compatible units on the same network.

Use the settings on the RollTrack screen to:

• Enable or disable the RollTrack functions.

• Configure up to 16 RollTrack outputs.

• Specify the conditions that trigger RollTrack data transmission.

• Set RollTrack destinations.

• Specify the RollTrack commands to be sent.

RollTrack Sources

The RollTrack Source specifies the source of the information that triggers the
tr

ansmission of data.

RollTrack Addresses

The full RollTrack Address comprises four sets of numbers. For example,
00

00:10:01*99.
The first set, 0000 in the example, is the network segment code number.
The second set, 10 in the example, identifies the (enclosure/mainframe) unit.
The third set, 01 in the example, identifies the slot number in the unit.
The fourth set, 99 in the example, is the RollCall ID of the destination unit - a user-

configured number that uniquely identifies the destination unit in a multi-unit
system. If it is set to anything other than 00 the unit will respond to RollTrack
commands. If left at 00, an incorrectly fitted unit may respond inappropriately.

RollTrack Commands

Each RollTrack command co mprises two sets of n

umbers, for example, 33039:3.

The first set, 33039 in the example, is the RollTrack command number, which
identifies the command.

The second set, 3 in the example, is the value that is sent with the command.

Using RollTracks

To enable or disable RollTrack functions:

•

To enable the RollTrack functions, clear the Disable All check box.

Version 1 Issue 1 www.snellgroup.com IQOTR30

Page 18

• To disable RollTrack functions, select the Disable All check box.
To configure a RollTrack action:

1. Select the Index number. This identifies the RollTrack action being config-

ured. Up to 16 RollTrack actions can be created.

2. From the Source list, select the source of the information that will trigger Roll-

Track transmission.

3. Enter the RollTrack Address and click S. To return the address to its default

value, click the preset button (P).

4. Enter the RollTrack Command and click S. To return the value to its default,

click the preset button (P).

Viewing RollTrack Information
RollTrack Sending and RollTrack Status display information about the status

of RollTracks.
RollTrack Sending displays the information when the unit is actively sending a

RollTrack command:

• No: The command is not being sent.

• Yes: The command is being sent.
RollTrack Status displays the status of the currently selected RollTrack Index:

• OK: RollTrack message sent and received OK.

• Unknown: RollTrack message has been sent but has not yet completed.

• Timeout: RollTrack message sent, but acknowledgement not received. This

could be because the destination unit is not at the specified location.

• Bad: RollTrack message has not been sent correctly, acknowledged at the

destination unit. This could be because the destina tio n unit is not of the type
specified.

• Disabled: RollTrack sending is disabled.

Operation from an Active Control Panel

The module can be operated from an active control panel via the RollCall™
network.

All operational parameters and selections described in the previous section are
made using a system of menus displayed in the two LCD windows – the
Information window and the Control window.

Information Window

The information window contains four lines of text indicating the current state of
the unit.

Control Window

The Control window displays all selection menus and sub-menus.
The main or top level menu allows various sub-menu s to be selected by pressing

the button adjacent to the required text line.
Note that where a menu item is followed by three dots (...) this indicates that a

further sub-menu may be selected.
Whenever a menu item is selected the parameters of that selection will be

displayed in the Information window of the front panel. Where the selection is
purely a mode selection and does not enable a sub-menu, the text will become
reversed (white-on-black) indicating that the mode is active. If the mode is not
available for selection the text will remain normal.
