Communications Support Forums
Hi guys,
I'd like to ask for help from you. I have an Astro Spectra Plus with the Astro Packet Data FLASHport option enabled. I can select the Data menus in the CPS, I can enter IP addresses and select the communication method too (FNE or Direct).
I began to do some research on the Internet regarding the data communication between ASTRO25 mobile units, using Direct communication. Now I am confused because it is not really clear how to do this. Some Internet topics mention that I will have to install the radio in Windows and other don't mention this anywhere. So I don't know how to proceed, because I have found no windows driver for these radios.
I have read that I may success if I install the radio as a regular 2400 bps modem. But what about setting up the IP addresses? I've found 4 instances of IP address in the CPS. My PC uses a static IP address on the network.
What I already know (correct me if I am wrong):
- W947 Packet Data option is required to set up the radio to transfer packet data
- a direct connection can be used from the PC to the radio, no level converter needed (because there is an RS232/TTL converter inside the radio)
- I must select Direct communication in the CPS instead of FNE
- data communication only works on P25 digital channels, if this feature is enabled
- the radio will take care of controlling the PTT when data stream is sent to it, it will use the RS232 data lines, no external PTT switch is needed
- the connection speed will be slow, yes I am aware of that
- transfer type must be set to half-duplex, since the radio is not full-duplex (but I don't know where can I set this in Windows)
- communication type should be set to 'communication cable between two computers' like this:
https://powerlink.emc.com/nsepn/web...ts/configure_PPP_on_your_windows_computer.htm
My questions are:
- how to set up the IP address fields in the CPS?
- how to set up Windows to communicate with the radio using an RS232 cable connected to the COM port? (I have Win2000/XP and Win 7 too)
- is there a Windows driver for the radio to act as a default modem?
- what applications can be used to communicate over the radio, like if it was a modem (are there any HAM radio applications?)
I think that's all for now
Any help is welcome!
