DigiMaster PRO DATA interface

ALWAYS ENSURE THAT YOUR INTERFACE IS PLUGGED IN
AND TURNED ON BEFORE STARTING YOUR SOFTWARE.

ALWAYS TURN YOUR RADIO AND THE INTERFACE OFF WHILE PLUGGING OR UNPLUGGING CABLES.
DOUBLE CHECK CABLE CONNECTIONS ARE CORRECT AND SECURE, THIS MAY SAVE YOU TIME LATER.

Quick Start

For connections see the first diagram above.
Note: If your radio is a Yaesu and you have a 6 pin DATA socket and an 8 pin CAT socket be careful and ensure you connect the 6 pin plug to the 6 pin soscket and the 8 pin plug to the 8 pin socket otherwise you may damage on or more pins in the 8 pin plug.
Plug the USB cable from the interface into the PC and switch on.
Windows will detect the USB interface and either install the drivers automatically, or ask you for the driver.
If Windows asks you for the driver, you can download the latest driver using the link Click here for latest USB drivers and USB installation guides..
If windows asks you for the driver, you can also decide to allow windows to "search the net", doing this will ensure that you always get the latest driver.
After installation of the driver, the LED will alternate green/red several times, this indicates that the driver has been installed and the the USB section of the interface is working. With the cables connected to the radio (specifically the DATA cable) your radio will also switch between RX and TX several times each time you power up the interface, this is normal Windows operation and Windows does this to test the interface each sees the USB device.
You can check driver installation using Device Manager Click here for help using Windows and Device Manager to identify virtual comports (PDF).
The LED will toggle RX / TX at every time you power up the interface, this is Windows normal procedure as it tests the interface and this action proves the interface is recognise and can be controlled by software.
The LED when green indicates power is on and the interface is in receive. When red, the LED indicates TX, either DATA or CW.
Open device manager and view comports, you will see 2 comports that you did not previously have.
If you are unsure which they are, turn the interface off and the 2 comports will disappear from the comport view.
Switch the interface back on and they will reappear.Windows will also toggle RX / TX again when it sees the interface power up.
Note the comport numbers, you will need these later when configuring your software.
REMEMBER, if you swap the interface between USB ports on your PC, Windows may reassign the virtual comport numbers, if it does so, then your softwares configuration will need changing to reflect this. The virtual comports provided by Windows will almost certainly be different on a different PC.
Windows will assign the 2 comport numbers and there is no way to know in advance what numbers windows will assign.
However, Windows will normally number these consecutively. I will call these comports [x] and [x+1].
Comport [x] is used by the interface to control PTT and CW lines.
Configure your DATA mode software so that comport[x] (the lower numbered of the two new comports) is used for PTT and the "DTR".
Your software needs configuring so that RTS=PTT and DTR=CW. That's all you need to do to configure your DATA mode software and you do not configure comport[x] any further.
REMEMBER, if you swap the interface between USB ports on your PC, Windows may reassign the virtual comport numbers, if it does so, then your softwares configuration will need changing to reflect this. The virtual comports provided by Windows will almost certainly be different on a different PC.
Configure your radio. The radio will also have a setting for the CW key, it should be set as a normal / straight key.
Other radios need more configuration, (the 857 for example) when used in DATA modes needs to be set in "DIG" mode, which you should have previously configured (radios menu system) to be USR-USB. (consult your radios operator manual).
Many radios that use the 6 pin DATA socket also need to be configured so that the 6 pin DATA socket is selected for use.

If you don't configure the radio correctly then things probably won't operate as you would expect.
Advice, DO NOT RELY on using PTT via the CAT system for DATA transmission. This may work with the majority of radios but some, including ALL Kenwood radios open only the microphone socket and not the DATA socket when TXing via the CAT system. Always use the DATA interface (comport[x] RTS line for PTT and you will always have success when transmitting DATA.

To configure the CAT software, you use the second "virtual" comport, which is comport[x+1], (the higher of the 2 virtual comports created by the interface - this is NOT the same virtual comport that you just configured for the DATA interface above).
Some radios like the 817,857,897 have a multifunction CAT socket which can be set for other use than CAT, if you have one of these radios or a radio with a multifunction cat socket then you should use the radios menu system and set the multifunction socket for use as CAT rather than linear or atu.
Whatever radio you are using you may also need to use the radios menu system to configure and enable the radio's CAT system before you can access its CAT capabilities. In all cases where your radio has a menu system, you should use the menu system to obtain several settings from the radio. Baudrate, and in the case of Icom the CIV address, (consult your radios operator manual).
In your software you normally select your radio from a list, then select the appropriate comport, use the baudrate as set on the radio (this can often be changed via the radios menu system and so you should check the setting on the radio), if your using an Icom, then also set the CIV address (again this can often be set via the radio menu system). You should double check baudrate and CIV address.
When you have checked the settings on the radio and have duplicated the settings in the software you then select the comport, this is comport[x+1].
If you specify any paremeter wrongly you not get a CAT connection. You wont hurt anything other than your pride.
If you have the parameters set correctly you will get a CAT connection.

You do NOT need to select DTR or RTS when configuring the second virtual comport for CAT as these settings will make no difference to the DigiMaster PRO's CAT system.
Note: The RED LED will not come on when using CAT - If it does your trying to use the wrong virtual comport for CAT.
There is not a lot of configuration to do, but two virtual comports can be confusing for those who struggle with PC's.
