When sent in the broadcast mode, it can be used to collect the replies from all locally attached Device Servers. But why this command doesn't return the IP-address of the DS100/EM100 as well? So, how do I find out which IP-addresses correspond to the MAC-addresses of the Device Servers that have replied to my broadcast? text/html 2008-09-09T14:15:04+04:00 http://tibbo.com/kb/fixed/usecase/hypertrm_file_xfer?rev=1220955304&do=diff Question: I am trying to do the following: Connect a DS100 to COM1 and to the network. I open Hyperterminal from com1 and another terminal with TCP/IP (to the IP address of the DS). The DS is in slave mode. I open the connection from the TCP terminal first and when I type something everything works fine and I see it on the other terminal (connected to the COM port). text/html 2008-09-09T14:31:28+04:00 http://tibbo.com/kb/fixed/usecase/multi_dest?rev=1220956288&do=diff Question: Can I make a Device Server send data to several other DS100s, all at the same time? Answer: Yes -- this is possible. As an example you can imagine a system of several network-enabled clocks that are kept synchronized by a single timekeeping source. This source sends updating messages and it is important that those messages reach the clocks at exactly the same time (or with minimum time deviations). text/html 2008-09-09T14:31:42+04:00 http://tibbo.com/kb/fixed/usecase/multi_dest_modem?rev=1220956302&do=diff Question: Can I use serial commands to change the Destination Address of the DS so that it would send to a different destination, or even a series of destinations one after the other? Answer: There is a special type of command, called modem commands which can be used to accomplish this. text/html 2008-09-09T14:31:54+04:00 http://tibbo.com/kb/fixed/usecase/multi_dest_no_prefix?rev=1220956314&do=diff Question: We want to use multi-destination mode of your VSP but we don't have a prefix character in our serial communications protocol. Our protocol is like this: address (1 byte) + packet content + ODH Anything we can do to make multi-destination work? text/html 2008-09-09T14:38:35+04:00 http://tibbo.com/kb/fixed/usecase/one_ds_many_comp?rev=1220956715&do=diff Question: I have one Device Server, and I want to receive data from it on several different computers on the network, all at the same time. How do I do this? Answer: This can be done using UDP Broadcast. Perform the following steps: Device Server Settings * Disable any and all firewalls you may have running, including Norton, Windows Firewall, etc. Firewalls often block broadcast traffic. * Go into DS Manager, and open the properties for the Device Server you want to configure. * Und… text/html 2008-09-09T14:38:50+04:00 http://tibbo.com/kb/fixed/usecase/one_ds_many_data_sources?rev=1220956730&do=diff Question: I want one DS to get data from several different sources. Can I do this? Answer: This is possible, but has some limitations. Read on to find out. An example of such an installation is a temperature monitoring system in which several temperature measurement nodes constantly send their information to a single destination. text/html 2008-09-09T14:46:01+04:00 http://tibbo.com/kb/fixed/usecase/rts_manual?rev=1220957161&do=diff Question: I would like to control the RTS line of the DS independently of the data sent over the port. I set the DS to: * SERIAL INTERFACE FULL DUPLEX * FLOW CONTROL DISABLED/REMOTE This way I can control the RTS line by RTS of virtual serial port - it works fine until I send data over serial port. At that time the RTS line goes ACTIVE. Why is that? How can I set the DS to independently control the RTS line?
