Error #1687 - Mototrbo CPS 12.1 and Windows 10

Error #1687 - Mototrbo CPS 12.1 and Windows 10

I know this is a common topic, but I have not been able to get anything to work in my weeks of searching, and I could really use some help. I am not a network or computer wizard.

I have a new to me Windows 10 Laptop with CPS 12.1 installed. CPS installed fine, drivers appeared to install fine, laptop recognizes my radios when I plug them in. I am using a known good OEM programming cable.

I get Error #1687 every time I try to read any portables or mobiles. I can see my XPR7550 under my devices as "MotoTRBO Radio", and I can see it under the device manager under Network Devices, and it says it is working properly.

No matter what I do, the radios will not read. Understand I am not trying to be spoon-fed, but I have exhausted all of my knowledge and nothing from the extensive searching I have done seems to work.

VE3WZW Answer :: 

Try disabling any firewalls and antivirus you have installed, Then try to read the radio. I find this a common cause for not being able to communicate with a radio. Also verify all the network settings are correct in windows for the radio. Below is what the help file says.

Unable to Communicate with the Radio



If the user is unable to communicate with the radios (example: error messages 595, 1687, etc.), do the following:

Verify that the MOTOTRBO device is powered-up properly. For a repeater, the Power light should be solid green, and either the Digital light or the Analog light should be solid (not blinking). For a portable radio, verify that the battery level is not low (for non-display portable radios, the LED blinks red when you press PTT if the battery is low).

Verify that the cable is in working order and that the ADS image is okay. On mobiles and portables, the 1-wire connect tone is heard through the speaker Additionally, display models will also show a momentary message.

Launch the CPS and then connect the USB cable to the PC. Verify that the cable is securely connected to both the device and the PC. Ensure that only one MOTOTRBO device is connected to the PC.

Verify the MOTOTRBO driver installation.

Exit ALL MOTOTRBO applications.

Right-click on My Computer and go to Properties. Go to the Hardware tab and click on the Device Manager button.

Expand the Network Adapters node.

Right-click on the MOTOTRBO Radio #X node and open up the Properties.

Verify that the Device status says “This device is working properly”. If it does not, then follow these steps:

Uninstall the driver.

Power-down the device.

Disconnect the cable from the PC.

Power-up the device.

Connect the cable to the PC.

Re-install the driver.

Verify the Network Connection settings.

Open up the Network Connections from the Control Panel.

Find the LAN connection associated with the Device Name “MOTOTRBO Radio #X.”

Right-click on the connection and open up the Properties.

Select the check box “Show icon in notification area when connected”.

Verify that the box “This connection uses the following items” has everything unchecked except for “Internet Protocol (TCP/IP).”.

Highlight “Internet Protocol (TCP/IP” and click on the Properties button.

Click on the Advanced button

Select the DNS tab.

Make sure that “Register this connection’s address in DNS” is not checked.

Power-down the device.

Disconnect the device.

Power-up the device.

Reconnect it to the PC and try again.

Check if the radio's IP address is detected. Launch a command window by selecting Windows -> Start -> Run... and type "cmd" in the dialog box. Then, type "ipconfg" in the command window.

Verify that the connection for the LAN connection associated with your MOTOTRBO device appears in the list.

Verify that this connection has valid values for IP Address and Default Gateway. By default this will be 192.168.10.2 and 192.168.10.1.

In the command prompt, try to ping the device IP Address. For example, type “ping 192.168.10.1”.

Right-click on the LAN connection notification icon associated with the device and select status.

Verify that the Packets Sent and Received are not zero.

Verify that the connection is Enabled. Press the button to toggle the device from disabled to enabled. (The button next to the Properties button should read “Disable”. If this button says “Enable”, click it.)

Ensure there are no conflicts in the route table.

In the command prompt, type “route print”.

A table with Active Routes: should come up.

Ensure that there is no conflict in the Network Destination column.

Disable any firewalls or anti-virus software installed on your PC, and try again.

Try connecting to the device using a different USB port.

If you are going directly through a PC USB port:

Try a different PC USB port.

Try connecting the MOTOTRBO device through a USB hub.

If you are going through a USB hub, try going directly through a PC port

Remove any LAN cables and other USB devices connected to the PC, disconnect the device, reset the device, and try again.

Disconnect the cable from both the device and the PC, reconnect using a different programming cable, and try again.

Try to reboot the PC and try again.

If all of the above fails, try to re-connecting to the device via a different PC.

Ensure that the non-signed driver installs is not blocked.

all TRBO radios work as a network adapter.

Caution with Windows 10 and MotoTRBO CPS (CPsoftware) .

The APX and MotoTRBO lines use IP over USB emulating ethernet, not serial over USB like the ASTRO25 line, but either way you didn't have to specify a COM port if you were using true USB cables. You're thinking of a USB to serial adapter.


SHOCKED MY SOLUTION:: 
Check and make sure your network and the admin network for the radios are not the same -- 

The radios by default are 192.168.1 / .2 an many off the shelf solutions for networks and routers also default to the 192.168.1.0/24 subnet.  

If both the radio and your LAN/WAN/VPN (any one of the three) are on the same subnet then you have a conflict and CPS does not work - 

You might also check your firewall settings an permissions for the program, there are many "security" setting in 10 that can affect CPS. 

One of the many good reasons for staying with 7.
