Is it possible to change the IP port used by the system e g if 4001 and 4002 are occu pied by another application Only port 4002 is used in communication to the PC and may be in conflict with other application is the same PC In version 4 you cannot change the port The risk for a conflict is seen as minimal If this should be a problem we will of course solve it There are no applications known so far that uses this port How is the traffic affected Use of sniffers We have during the development phase off course have been using sniffers three commercial and one of our own We have also bursted 10096 bandwidth to the SR34i to see the effects of the information quantity Both UDP and TCP This is however not quite so dramatic relative to a 100 Mbit LAN Bewator Entro Project Design Manual 45 Why not use VLAN VLAN is a good alternative to create a more secure network It is however difficult for Bewator to state general recommendations how to build the users own LAN There is no reason for using VLAN due to network load in an Entro TCP IP environment In general we recommend IT managers to use LAN switches rather than an Entro recommendation Is it possible to run Entro via Citrix VTS Mainframe v 1 8 We do not really support a configuration with Citrix and or PC Anywhere VNC etc However we cannot see why it should not work Remote programming can also beside modems be done via TCP IP Can database files

5. If an IOR6 is included in a Reservation object there are possibilities to fine tune how the reservation object is the used In many cases you may want to spread the wear of a group of machines E g that a machine is not used more than any else The relay in the IOR6 is activated the whole reserved time interval At the same time another relay in the same object can be activated by the same user but only a specified time E g opening time for a door Bewator Entro Project Design Manual 31 Lift Control Example In Bewator Entro there is an easy way of controlling the access to different floors in a building You can install readers on each lift door on every flat preventing access to the lift itself However this is a round about way of solving the problem By placing card readers inside the lift and forcing the users to use their card Bewator Entro and Lift control system will decide which button s the user will press Bewator Entro allows 32 IOR6 in a system with a total of 192 relays It is possible to split these into several lifts equipped with their own master reader or just one for 192 floors This function is true global which means that the IOR6 and the Master reader can be placed anywhere on the system It is advisable to use the Relay controller Bewator Entro IOR6 to interface the Lift Control and then use one reader on the system as a Master for this IOR6 This is to get the identity of the user Depending on the

Design Manual Example 3 LAN in same property This example is based on the earlier example 2 but will use local area network for communication between SR34i and PC The door environments do not have to be changed Suggestion It is very important that the IT manager of the company is involved at an early stage to define which IP addresses to use as well as the overall structure of the LAN routers firewalls etc In addition the LAN must be able to use 10 100 Mbit s Ethernet SR34i controllers have to be set up with the correct IP address The Installer program will supply this if the PC is inside the same logical subnet as the SR34is 3rd floor m 1 1 1 1 1 1 1 1 1 1 1 1 1 4 1 1 1 HF500 M43 i PR500 1 1 Entrance 3 Conf Room 2 Esas a ia iia ja i i i f i 2nd floor i di i i 4 i i i i HF500 M43 5 Prox i DTo5 Prox i PR500 Entrance 2 Computer Room i Accounts A Confroomi AAA IS et leale PSU i DC22 i AME 1 DC22 i 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1st floor 1 1 1 T 1 1 F L 1 1 1 i mg 1 1 1 1 1 1 1 1 1 1 1 HF500 M43 i HF500 M43 i 1 i Entrance 1 i 1 Warehouse

Readers with a keypad have a red LED which can indicate if the alarm is on Depending on which signal is connected the LED can be lit all the time go off after some time or flash It depends on the character of the output signal from the intruder alarms control units For example it is possible to have the ASF signal to control the LED in the way that it is initially ON but goes OFF after a software controlled time Bewator Entro Project Design Manual 23 Intelligent Alarm status feedback ASF There is a feature in the Bewator Entro which is called ASF Alarm Status Feedback it is a way of controlling the status of the alarm zone ON or OFF It also allows for the intruder alarm to completely control and disable the doors in the access control system E g a timer function automatically triggers an activation of the alarm while it is free to deactivate through a card reader or a control panel in the intruder alarm There is an option in the software for how to light the red LED Either it is controlled in parallel with the status signal or a separate signal If the DC22 is used there is a separate rely output pre warning for optionally connecting any sirens or similar to copy amp amplify the buzzer sound in the reader During this time an Exit Button request can still be used to unlock the door Intruder Alarm Controller ADDRESS i Alarm status feedback 17 32 m 501 lm 17 Sla 19 i

54. th machine control Bewator Entro Project Design Manual 43 Example 6 two PC in the same network In a larger Entro application there may be a need for allowing more system users to programme the system Different to earlier versions of Entro several users can be on line at the same time The prerequisites for this are that we know the names of the PCs to connect Every System user must specify which PC which event filter and where to store events on the PC When a system user logs on the system knows if events can be retrieved from the actual user The illustration below shows how two System users connect to Entro Manager PC TCP IP Connection to Entro system Receptionist PC TCP IP Figure 28 Several System Users 44 Bewator Entro Project Design Manual Advanced information about LAN The following chapter contains questions and answers regarding Bewator Entro when used in local area networks and is primarily aimed at IT managers What does the traffic load look like when it is using Entro in TCP IP LAN As Entro TCP is evolved with RS485 the traffic is relatively moderate providing that the database is hard packed The traffic SR34i will have a socket open to every other SR34i This socket is alive and is tested for failures with a special ping message every eight second in version 4 This is not an ICMP ping rather a common TCP IP package with some information only a few bytes in size Beside this
