Last Update: 4/5/89
Greetings!
Thank you for your interest in the RATS Open System Environment!
The following hardware [uggh] changes must be made to run the code:
If you are running on a TNC-2 [or Clone (ie. Z80 w/SIO)]
Then you MUST 1) Insert ROM and have fun
It would be nice if you added more memory, but it will run
with 16K-32K, with more users being supported with more memory.
If you are running a Pac-Comm DR-200
Then you MUST add the following jumpers:
Jumper U14/25 to U15/19
Jumper U16/25 to U15/21
U14 = 7910 Port A
U15 = 8530 SCC
U16 = 7910 Port B
This connects the DCD outputs of the 7910's to the SCC.
The clocks for the TX and RX of each port are now independent, to
set up the correct clocks use the following table:
U12 Pin RXClock TXClock
7 9600
5 4800
4 2400
6 1200
13 600
12 300 9600
14 4800
15 2400
1 1200
2 600
3 300
The SCC Pins are defined as follows:
Port # RXClock TXClock
0 U15 28 U15 26
1 U15 14 U15 12
For Dual port with both running at 1200 Baud
U15 28 and U15 14 to U12 6 (Set RXClock for each)
U15 26 and U14 12 to U12 1 (Set TXClock for each)
For 1200 Baud User port (Port 0) and 300 Baud trunk (HF)
U15 28 to U12 6 (RXC)
U15 26 to U12 1 (TXC)
U15 14 to U12 12 (RXC)
U15 12 to U12 3 (TXC)
I have not recently tested 9600 baud but will soon.
Pull the Watchdog timer out (U19), it doesn't seem to do anything.
Remove the RX Audio filtering (U17 and U20), the modem will work
better on it's own. I removed U17, R21, R23, Diodes at C24 and
installed a 0.1 uf at C24 and JP-FA. And the same for the other
port (Remove U20, R34, R33, Diodes at C45 and installed 0.1 uf at
C45 and JP-FB). If you use the modem on HF remember the tones are
425 hz higher (.5 khz on dial should be ok) and you need to reduce
the RF Gain so the background static is below 10mv (audio).
Might want to use the R33/R30 voltage divider and add jumper from
their junction to the other side of JP-FB and remove C41 and leave
JP-FB uninstalled.
NOTE: ***************************************************
The SAME ROM will work in both machine models, put
what-ever you want in the way of RAM, the INIT code
checks it all out and configures the Level 1 parms.
DR-200 Note:
The port that is next to the RESET pin is SCC Port B,
and is called port 0 to my code. Right now if you call
a user out of the switch it Always calls on port 0.
Unless you configure a User for another port, it's defined
like a Node with a path and MaxVC 0.
The Daughter board is not currently supported. (Very soon,
it has a TNC-2 style modem disconnect so it's the simplest
way to attach the NB-9600 High Speed modem)
The TNC-220 is not currently supported (soon, it's easy)
******************************************************************
Burn the ROM (27256), there is Intel Hex (ROSEZSW.HEX) and
binary (ROSEZSW.BIN).
Insert into your TNC-2 [or Clone]/DR-200
You will see the LEDs (if a TNC) flash about once a sec.
If they don't flash check for bent pins, etc, if still no good
then please call me (201) 478-7919 as the archive you got was
corrupted and I would like to fix it ASAP!
Install at site (well... connect a radio to it.)
Use the .CNF files as examples and modify one of them to model your
network. If you only have one switch then you will not have any
nodes other than "This Node" and there will be no "Route to nodes..."
The last line of the file is a WRITE statement specifing the output
file name (usually .TBL)
Run the Configuration program (CONFIGUR.EXE), it will create a file
(you specified the input filename). This will create the hex .TBL that
needs to be uploaded to the switch.
Connect to the switch with the following command:
C CONFIG VIA ROSE-3,000000
You will get a connect message that includes the Version number
Upload the configure data file(.TBL).
(You should get upto 12 "OK"'s and NO "Error"'s
When all the data is ack'ed, disconnect
The Switch is now configured, if you configured it with the call KJ4HP-3
and the address 502826 then to re-configure it you need to issue:
C CONFIG VIA KJ4HP-3,502826
I have included the MAP file so you can modify the default parms in the ROM
the switch call is at the address "mycall"
the switch digipeater call at address "mydigi"
the switch x.121 network address at "myadr"
The calls are in AX.25 format, ie. shifted ascii, 6 char followed by the SSID
The x.121 address is best shown by example:
myadr: db 10 ;Length of address in NIBBLES! (aka 4 bit chunks)
db 31h,00h ;Data Network Id Code for USA
db 20h,17h,79h ;Area Code 201, Exchange 779
db 0,0 ;a couple extra zero's for good measure
-----------------------------------------------------------------------
New Features:
DNIC support, the switch supports up to 8 different DNICS.
ex:
C VE7APU V N2DSY-3,3020,617385
and if you get a call from a different DNIC than the switch you use it will
also insert it in the out-bound call.
Routing:
You now can specify sets of addresses that a node will accept as it's own,
I have a switch here in Clifton, my phone number is (201) 478-7919, so I
use node address of 201478; Clifton also has exchanges 470, 772, 777, 778,
and 779. I can now configure W2VY-3 (201478) to handle 201470, 201772... as
local calls [as if the call had specified 201478].
Coming attractions:
I'd like to get 19.2 KB running, 9.6KB is shaky right now.
Coming very soon an interactive configuration program that will
allow traffic/stats monitoring.
And with the interactive configuration we will have authentication
of the configuration commands.
