1- STATUS DISPLAY
The upper half of the STATUS DISPLAY shows the status of up to 50 supervised subscriber positions
simultaneously. When a system has more than 50 supervised subscribers the ← and → (LEFT and RIGHT)
arrows are used to scroll the screen left and right one column at a time. The bottom half of the screen, used for
event handling, does not move. The upper half of the display will view the 50 subscribers in five columns of 10
rows. The station dial numbers will be on the left-hand side of each column while it’s status (OK, CALL, FAULT,
BUSY, etc.) will be on the right-hand side. Figure C6 shows an example of a status display with different
statuses for 10 different stations in the left-most column. All stations will be displayed in ascending numerical
order starting from the left, working down the column, and then moving to the next column to the right, etc.
Unused areas of the upper display area will show ellipses ( .... ) in place of station numbers and statuses.
If the DXC901, SUBSCRIBER ADDRESS $FF, is programmed as a SUBSCRIBER TYPE 1, with a text description and a
dial number code, the number will be displayed in the first column on the left. All reset activity from this stage
then can be printed to the defined printer. This is useful when a system is installed with many networks and/or
stages. Figure C5 & Figure C6 show what the DXC901 status would look like on the STATUS DISPLAY. It is the “01
OK” on the top line of the leftmost column. Figure C12 shows what the NETWORK CONFIGURATION should look like
to get this result on the STATUS DISPLAY. (See NETWORK CONFIGURATION - SUBSCRIBER ADDRESS later in this chapter
for more details).
The lower half of the status display screen indicates status of five incoming annunciated events. If more than five
annunciated events are in queue (QUE), use the ↑ and ↓ (UP and DOWN) arrows to scroll to your choice. There
is room in the queue for up to 60 annunciated events.

Additional Status For Master Display Line :
IDLE - Indicates no DNA100 activity present at the master station.
DIAL - Indicates the DNA100 sent a request to dial. It sends a request to dial when an attempt is made to
answer an incoming event.
WAIT - Indicates status change for master. No keyboard entries will be accepted during WAIT state. WAIT
status occurs after the master cancels an event that was handled.
TALK - Master station is in conversation initiated by the DNA100. The DNA100 must be used to cancel the
conversation to remove the TALK status from the display line.
Operation :
IDLE -
When there are no annunciations (ALARMS, FAULTS or CALLS) to display, QUE will display 00, the TIME will always
be visible and the event display lines will be off. The real-time status display will show all stations programmed to
report to this annunciator as OK unless FAULTS are present in the system. In IDLE mode the Intercom master
station assigned to the CRT will also be idle and may be used in normal intercom mode by using the dial pad on
that station. Unused slots on the screen are filled with ellipses (...dots....).
INCOMING EVENT -
When the CRT DISPLAY receives an event a display line will appear and an audible tone will be heard from the
terminal. There is room to display five events in the queue. The middle line will be highlighted as the current line
that can be activated. See HANDLING MULTIPLE INCOMING ANNUNCIATIONS later in this chapter. The QUE will show the
number of display lines in use. The user should always note the status of the event (ALARM, CALL, FAULT, PARK)
before responding since the incoming status of the line will not be apparent when answered. The event lines will
be placed in queue in the order they are received if they all have equal priority. When an event with greater
priority is received it is placed ahead of existing events with lower priority level. Priority ( PRI) level is
programmable from 1 through 9, 1 being top priority (see NETWORK CONFIGURATION for programming).
HANDLING AN EVENT - The SPACE BAR
Once the status has been observed, the current highlighted display line can be answered by pressing the SPACE
BAR on the CRT keyboard. When the SPACE BAR is pressed, the audible annunciation tone will stop, and the
DXC901 will connect the intercom master station at the CRT DISPLAY with the substation that initiated the event.
A warning tone will sound at both stations, and you may begin speaking after the tone. The intercom will
normally switch your voice hands free, although it may be necessary to use the 'T' button on the intercom station
for simplex operation (push to talk) to overcome background noise at either location. The 'T' may also be used
whenever you want to continue monitoring a station for information or security reasons.
11

PRIORITY OVERRIDE - Intercom Privilege Feature
The master station at the CRT DISPLAY should be programmed with the "Priority override" privilege by SVT. If a
busy or privacy signal is encountered, you may then press the 0 (zero) key on the intercom to override the signal
and obtain voice contact before the intercom times out (default is 15 seconds for time out). If the intercom times
out, you must dial the EXTENSION number shown on the DISPLAY line manually on the intercom ignoring leading
zeros, and then use the priority override privilege. All substations reporting to an annunciator may also be
programmed with "Privacy Category, Never" through SVT to avoid having to use the Priority feature on a station
that appears in privacy.
REMOTE CONTROL - The O key
This key is used for Door Lock Control of the connected Substation.
EX901 sends DTMF digit 5 to Substation
EX500 sends DTMF digit 5 to Substation
DXC901 sends DTMF digit 5 to Substation
DXC910 sends DTMF digit 5 to Substation
DXA100 sends out event REMCON
CANCEL A CONNECTION - The X key
When the intercom call is completed, press the X key on the CRT DISPLAY keyboard, this will cancel both the
intercom connection and the current DISPLAY line.
A FAULT will return within two seconds after being canceled if it is a solid fault. FAULTS can occur intermittently
during the scanning of the system due to electrical interference or disturbance at, or near, the station or its cable.
Each substation is scanned for faults 80 times per second. Hard faults can be removed from the system
temporarily by setting their device type to 0 in NETWORK CONFIGURATION and then reprogramming when the fault is
corrected.
PARK - The P key
PARK is used to temporarily hold events that you need to get back to after handling other events or obtaining
information.
HANDLING MULTIPLE INCOMING EVENTS -
If the QUE indicator displays a number greater than five, you can use the ↑ or ↓ (UP or DOWN) arrow keys to
view the additional events and decide which lines should be handled first based on location of event or PRIORITY
level. If the scrolling feature is not used, events can be handled on a first in first out basis by starting at the
current line. When each event is canceled each DISPLAY line will automatically move into the middle highlighted
line, and the middle DISPLAY line will be used each time until all lines are handled.
12
June 2017 Digital Network Adapter DNA100
Ring-Master
SILENCING THE AUDIBLE ANNUNCIATOR TONE -
When an incoming event is received and cannot be handled immediately, the tone can be temporarily silenced
by pressing the X key on the terminal keyboard. If any additional activity occurs, the audible annunciation tone
will sound again.
The audible tone will also sound if another event is received while you are presently handling one. Two options
are available to handle an event while in conversation: One is to complete the present event, press cancel, then
proceed to handle the additional events. The second option is to place the present event in PARK, then answer
the additional events to assess the priority of the event handling using Park or “X” (cancel) as needed.

NIGHT TRANSFER MODE -
The DNA100 is placed in Night Transfer mode by placing the associated intercom station in privacy. Calls to this
DNA100 will now be sent to the next Annunciator device in the Annunciator address chain (for the sub station)
without the programmed delay. The delay is used in normal Day mode to delay calls before they transfer (Max
delay 9.9 minutes). When the DNA100 is in transfer mode the time display will flash the word “TRANSFER” .
Calls are still qued in the DNA100 but the beeper is silenced. The beeper will beep once every 60 seconds as a
reminder that the we are in transfer mode. The DNA100 may answer calls in the Que while in transfer mode.

NETWORK MONITOR
The NETWORK MONITOR is activated by selecting option five on the MAIN MENU screen. The NETWORK MONITOR
allows real time viewing of all networks and nodes presently operating in a Crisis System. This screen should be
used by technical personnel to verify network operation during installation and trouble shooting. The NODES
shown are as seen by the master of that network. FREE, RETR, and RXERR are master information as well. To
return to the MAIN MENU at any time press ESC.
When a node number is displayed steady (not flashing on and off) and the error columns are zero and/or not
incrementing then those nodes are 'on-line' and working. Node numbers that are flashing may also increase the
RETR and RXERR counters and indicate a trouble on that network. This could be due to an internal failure in a
node or a poor data connection in the network.
If the network has excessive traffic, the FREE pool of elements will become depleted. This could lead to loss of
communication with this node or network. Excessive traffic can be caused by one defective node, poor quality or
damaged data pairs.

NET - Network number. Networks 01-30 are for standard nodes, 00 is not used, and 31 is reserved for a
DIGITAL EXCHANGE MASTER bridge.
NODES - Node number. The master of that network is receiving messages from the nodes displayed. Node
numbers are from 0-7 listed from right to left.
FREE - The number of free queue elements for transmission. In each node, there is a free pool of message
locations that can contain queued up messages generated for the node’s internal housekeeping. When queued
messages are handled, the queue element is placed back into the pool. This number is the remaining queue
elements that can be used by the master node. This number is usually HEX 28 but will decrease depending on
data traffic.
RETR - The number of retransmissions logged by the master of this network. To reset the counter the
master must be reset. Some retransmissions may exist on a good network due to data disturbance when
installing or removing a node, or if transmissions are sent to a node that is not present on the system.
RXERR - Number of receive errors logged by the master of this network. To reset the counter the master
must be reset.

NETWORK INFORMATION
NETWORK INFORMATION is activated by selecting option five on the MAIN MENU screen. Then enter a network
number or * to view all networks. This screen can be used if there is a question about how the network is
operating or if you want to see details about individual nodes on the system. While NETWORK MONITOR shows
information based on the master’s point of view, NETWORK INFORMATION shows information from the individual
node’s point of view. The information here is based on each node as opposed to the entire network. It’s very
useful for finding that errant node or for general information about each node in the system. Each line represents
one node in the system and displays information described on the next page.
Unlike NETWORK MONITOR, NETWORK INFORMATION is not a real time display. The information displayed is not
updated while in NETWORK INFORMATION, to update the information you must exit and then re-enter.
To exit and return to the MAIN MENU at any time, press ESC.

ADDR - Network address. The network address of the node on that display line.
NET - Network number. The network the device on the display line is a member of.
NODE - Node number. The node number of the device on the display line.
TYPE - Type of device. The device type (DXC901, DNA100, DAD104, etc.) of the node on that
display line.
VERSION - Version date. The version date of the device on this display line. The date is in the format of
YYYY/MM/DD (year, month, day). To be compatible with the NETWORK INFORMATION screen the version date of the
firmware has to be dated 960105 or later. If the firmware in the device is older, it will display asterisks (***) in
place of TYPE and nothing else to the right of TYPE for that display line.
FREE - The number of free queue elements for transmission. In each node, there is a free pool of
message locations that can contain queued up messages generated for the node’s internal housekeeping. When
queued messages are handled, the queue element is placed back into the pool. This number is the remaining
queue elements that can be used by the device on this display line. This number is usually HEX 28 but will
decrease depending on data traffic.
RETR - The actual number of retransmitted messages logged from the device on this display line. To
reset the counter this device must be reset. Some retransmissions may exist on a good network due to data
disturbance when installing or removing a node, or if transmissions are sent to a node that is not present on the
system.
RXERR - Number of receive errors logged by the device on this display line. To reset the counter the
device on this display line must be reset.
HOURS - Time since reset. Number of hours in hexadecimal format.

PACKET MONITOR
Option eight on the main menu is PACKET MONITOR. This feature allows a technical person to actually view the
data packets on the network. This monitor is a powerful debugging tool used primarily for software development
and testing although it also can be utilized for trouble shooting.
To exit and return to the MAIN MENU, press Esc. This will reset the DNA100.
Each lettered item in the example indicated by an arrow is described on the following page. These descriptions
are intended to assist field personnel to explain PACKET MONITOR listings to a Ring Communications technician.
They are not intended for a complete understanding of the data packets on the network.

A = Error counter. Maintains total number of errors on network. This number is stored in the network master and
can be reset by resetting the network master. A secure network will have no errors but some are possible if
nodes are installed or disconnected and cause data disturbance.
Possible errors are:
- checksum error
- network error
- receiver overrun error
- noise error
- framing error
- number of retransmits
B = To node. In this example FF indicates a broadcast to all nodes. Other numbers indicate a node address.
C = From node. The example shows node 0C sending to FF (broadcast).
D = Event definition CALL, CONNECT, CLEAR, PARK, TALK, BUSY, etc.
E = Total number of bytes in this packet, 09.
F = Device to/from. The node may represent a device such as a master station. The example shows device 01
(line equipment 01 is the second subscriber port in the CB901) sending to FF (broadcast)
G = Checksum. The total of all data in the packet. This is recalculated when received and checked for accuracy.
If the calculated checksum does not match the received checksum then a request to retransmit the packet
occurs.
H = Time. Time is transmitted by the network master as a broadcast and the time may also be part of a packet
indicating when an event occurred. The format is SS:MM:HH (45:40:19).
I = Date. Date is transmitted by the network master as a broadcast and the date may also be part of a packet
indicating when an event occurred. The format is DD:MM:YY (08:01:03).
J = ASCII text field. The 30 character description for this device.

ACTIVITY LOG PRINTER
A serial RS232C printer can be attached to a DNA100 to provide a complete activity log of system. All stations to
be logged must have the printer defined in their SAR. The DNA100 must be configured to drive a printer by
setting SW3-7 off and SW3-8 on. The printer must have a RS232C serial interface. The standard print format is
80 columns, 66 lines per page.
Figure C16 shows a sample printed page of the Crisis Alert Activity Log Printer.
Description of Status Headings :
DATE The DATE this page was printed. If the date changes before the page is full a new page is printed
with events for the new date.
TIME The actual time the event on each line occurred.
PRI PRIORITY of the incoming event.
STATUS Status of each event (CALL, FAULT, CONNECT, PARK, CANCEL, RESET, ALARM).
EXT The dial number of the station generating the event.
LOCATION DESCRIPTION Written description of the location or device stated under the EXT heading.
CONNECTED TO Indicates the station connected to the device generating the event.
Description of Status :
CALL CALL to annunciator. This only indicates a call condition was placed from type 1 sub station or
type 3 sub-master station.
CONNECT Indicates an event being handled in accordance with the annunciator display through Crisis
Alert. (See HANDLING AN EVENT earlier in this Chapter or in Chapter D - DAD104)
FAULT Indicates a hardware problem for the location printed and sent to the annunciator five seconds after the
fault occurs. The time delay is due to a noise filter in the DXC901 that only records solid faults.
PARK An event that was placed in PARK. A new CONNECT message will be generated when this event is
retrieved again.
CANCEL Indicates a disconnection of two devices that were previously connected. For example, a
master station that presses the ‘X’ key on the terminal keyboard using a DNA100 will generate a CANCEL event.
ALARM ALARM to annunciator. This indicates that an alarm condition was placed from a type 3 sub-master
station.
PWRFAIL The CB901 has detected loss of Power. It is now running on battery backup.
ACKNOWL An event has been acknowledged by a DAD104 (such as PWRFAIL).
CLEAR The Power has been restored to normal for the CB901 central exchange.

Additional Status For Devices :
RESET Indicates when a device has been RESET. This message is only printed if the device has a Printer
Address defined during NETWORK CONFIGURATION. To enter a description for the DXC901 Digital Exchange
Controller use Subscriber address $FF and enter it as a SUBSCRIBER TYPE 0 station with the description needed.
The dial number if inserted can be displayed on a CRT status display. Generally a two digit number is used to
indicate a building or stage number in a multi stage configuration. Do not enter a priority or program channel for
the DXC901.
