Pete, I would like to hear more about this. Consider me an infant in 'network' and use really simple terms.
I have an old Dell computer that runs Win2KPro with two serial ports built in that was discarded by my office. I use it to communicate with a TBolt and a Z3816A. The ability to communicate with several other serial ports would be beneficial but the thought of getting several PCI/Serial cards for the computer seemed like the only option. I would love to hear of other options, particularly for 'pennies'.

Like many time-nuts I have quite a few devices that communicate to the outside world with a serial port. And like many I have more then one. In a past life I use to have to connect to sometimes a 100 RS232 in one location. A popular device is called a terminal server or concentrator. They would take from 1 to 48 RS232 ports on one side and let you talk to them via an Ethernet interface. I so far have twelve RS232 ports in use. Now that the need for such devices has diminished, these terminal servers are showing up, sometimes for pennies. One brand and model Digi's TS family of models I and have verified they work with Lady Heather and Trimble Studio on a Windows XP PC. Digi offers for free a program that makes each RS232 Port look like a COM port, and after configuring the terminal server, and this driver, you just just fire up Lady Heather pointing to the correct "COM Port". Other RS232 ports on the terminal server can either be COM ports, or one can be connected to via Telnet of for security SSH. For example I have an Odetics on one port and I just enter telnet ts4a (the DNS name I gave one of the terminal servers) 2003 (the IP port associated with the third RS232 port). So if this is of interest to anyone I'll go into more detail, models, setup etc. -pete -pete _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
