april 2012 digital network adapter DNA100 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. 21 ring-master www.datasheet.net/ datasheet pdf - http://www..co.kr/
april 2012 digital network adapter DNA100 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 d ate 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 p riority of the incoming event. status status of each event ( c all , f ault , c onnect , p ark , c ancel , r eset , a larm ). 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 c all 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 h andling a n e vent 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 p ark . a new c onnect 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 c ancel event. alarm a larm 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. 22 ring-master www.datasheet.net/ datasheet pdf - http://www..co.kr/
