What is the max baud rate for the spare RS-232 port?

Hi

I have not used more than 38400 bits/s in real life on the extra serial port.  But I will check ASAP.
The serialport for the radio is often used at 57600 (TS-480 and TS-2000) so 57600 should not be any problem for the extra serial port either, but I don't know about 115200 ?

How can I know if the 2nd RS232 'bridge' is UP?

Hi

If the second serial port (uart 0) its activated in both end, it will be up at the same time as the rest of the communication is up, it's sent over the same UDP port default 12000 as the other data between the boxes. There is no separate status indication for it.

My idea is to use hamradio deluxe to control the radio (and then sync the frequency with my local radio) but is not possible to connect the radio, even @9600 bps.
Now I have simplified my test with a simple kantronics TNC: both RRC are configured 19200,8,1,0 (uart0 = 1 - enabled), traditional modem cable (25pin to 9 pin female) + male/male 1-1 gender (RXD TXD GND).

On 'local' RRC (display) there is a female/male rs232 (1-1) cable to the com1 of my PC.
I open an hyper terminal session on com1 / 19200 bps and... nothing.

If I start one RRC in a debug mode (telnet window), all TTL display traffic is 'slowed' but on my hyper terminal window I receive the kantronics welcome message. I restart all in normal mode and newly nothing on my screen.
Now I have tested also hamradio deluxe with a RRC in a debug mode but always not connected.

What's wrong?

HI

I don't now about the Kantronics. But lot of people using RRC with HamRadio De Luxe.
The most common problem people have is that they have forgot to connect  pin 7-8 together in the d-sub at radioend if they use Yaesu or Kenwood.

Hey Mike! On your page (http://www.remoterig.com/en/tekniskbeskr.htm) you write:

RS232 Interface (9-pol D-sub female)
 
1
2 TXD (Out)
3 RXD (in)
4
5 GND
6
7
8
 
So in my cable I used only RXD/TXD and GND. Now tested with an icom CAT and hamradio deluxe and it works. Please add some info on your website.
Now I check with pin 7+8...

Hi

Yes but the 7-8 loop has nothing to do with the RRC it's needed by the radio, so it's described on the radio cable drawings.

for example

http://www.remoterig.com/en/kenwood_gen.htm

so it's in the radio end it should be a connection between 7-8 against the radio

Ok thanks, now the second RS232 works also with my TS480, so for other users my solution is:

RRC (Display side)
===================
PC with hamradio deluxe @38400 bps (@57600 it doesn't connect) and 'commercial' rs232 1-1 male/female


Settings on both sides
======================
Redirect Uart 0  -> 1
Uart 0 baudrate  -> 38400
Uart 0 data bits -> 8 
Uart 0 stop bits -> 1
Uart 0 parity -> 0


RRC (remote side / TS-480)
==========================

RS232 male / female
2 -> 3
3 -> 2
5 -> 5
7 -> 8
8 -> 7


How to synch 2 radio with hamradio deluxe
=========================================
Open HRD and connect to your first radio (in my case local radio)
Open another HRD window and connect your second radio (in my case remote TS-480)
Press Synch button on the toolbar
Click scan and start. That's all

Now you have 2 radio in a diversity reception; turn the vfo or band on your master radio and the second radio turn also...
