General Step to set up your CS750 for PRN communication in the Carolinas area

  • You need at least a Technical level license in Amateur Radio.
  • After buying the CS750 radio, let is fully charge for several hours in the charger
  • Confirm that you have all necessary hardware and software for the firmware update. The programming software works only on a Windows-based computer at this time. (See CHECK YOUR FIRMWARE VERSION below). For example, my firmware version was S3.00.07 and Bootloader version was D2.01.
  • 3rd Install the programming software on a PC
  • Follow the manufacturer instructions to connect the radio with the provided USB cable.
  • To upgrade the Firmware you will need the FlashBurn Software and you will need to get the latest version from the connectsystems.com software area. You will also need to download the latest “Firmware Version” and/or “Bootloader Version” if your radio does not have the latest. The files are labeled the versions. For example, my CS750 said that my latest of the Bootloader is D2.01 and the latest on the company website was “Bootloader Version 2.01” so I don’t need to update it but my radio said the firmware version was s3.00.07 and the latest on the website was “Firmware Version 3.00.10” so I want to update that.  It can be a bit confusing for you just need to scroll down from the top and see the latest version. For example at the time I got my cs750 the latest version was “FlashBurn Version 2.00”. It is a zipped file, then open that and look for FlashBurn (latest number) Application to open. Then run FlashBurn (latest version) that appears after that. This will open the FlashBurn software with instruction on how to add the latest Fashware which you also need to download from the same page looking the latest version. For example at the time I bought my CS750 the latest firmware version on the website was “Firmware Version 3.00.10”.
    •  You will need to connect the radio to the computer with the cable (turned off) then press and hold down the PTT key and the Top key (orange) key while turning on the CS750. Next click Select(*.bin) and find the download update (eg. Firmware Version 3.00.10 is CS75X_S3.00.10.bin). Finally, select Flash and wait for the screen to say it is complete and the radio is finished. Now follow the menu instructions on the radio to check the latest version and one mine it now reads “Firmware Ver. S3.00.10″ and it had showed Firmware Ver. S3.00.07” before.
    • Photo of the FlashBurn Software and how it looks when completed:

      flashburn2
  • Next you need to register your callsign for digital use by going to:
    •  Registration page for Digital Voice Services – http://register.ham-digital.net/
    • Next select “Register services for an individual callsign (no repeater!).”, enter your call sign.
    • Next select “Request a DMR-ID to use a DMR-network.”, click OK
    • digital reg
    • Scroll to the bottom and select “User Registration”
    • Enter your call sign and select “validate”.
    • Check that the call sign info is correct and enter the “Nickname” you want to show up. Mine is just my 1st name “Martin”. Enter your City (eg. Raleigh), select your state (eg. North Carolina), Radio type should be set to “DMR”, enter your email and a comment if you want to let them know something. I just added that I just bought at CS750 and setting it up, Type in the “reCAPTCHA” to prove your are human. Last you should see a compelte screen with a message like “Thank you, You will be contacted by email and provided with the ID you requested shortly. **NOTE: Please check the database for your ID before contacting the ID Team if you do not receive an email within 48hrs, We get blocked by mail servers as SPAM a lot because our emails are template driven and always the same. Also check your own SPAM folders.”
    • digital reg 2
  • Next, you need to get the latest “Code Plug” with all your local repeaters in it and install it using the software. For the Southern code plug go here:
    http://ncprn.net/?page_id=36  Read this “Getting Started” page: http://ncprn.net/?page_id=28
  • After you install the code plug with the software you should be ready to go!

 

** Quotes from the manual and connect systems webpage related to the CS750d that I thought were worth posting here **

“Programming software for the radio can be downloaded from the Connect Systems Site.

Etiquette 

  • When calling out say the channel name then your call sign. For example: “KI4CFS on Cary PRN, monitoring, and mobile.

Terms to understand:

  • DMR: DMR Programming for Amateur Radio – “Digital Mobile Radio (DMR) is an international digital radio standard developed by the European Telecommunications Standards Institute (ETSI), and first ratified in 2005.” http://www.taitradioacademy.com/topic/what-is-dmr/ – Another Video explaining DMR https://youtu.be/0t-cyOQbGxc
  • Code Plug – A unique table with information read by the CPS programming software to add repeaters and setting to your radio. It also tells it what frequencies to transmit and receive, RF power output, carrier squelch/coded squelch, signaling modes, and whatever other features the specific radio might have you want enabled.
    “Back in the good old days, radios used crystals to control the frequencies, and sometimes had internal jumpers that were set for the various options. Some time later on, they moved the internal jumpers to a jack on the back of the radio. They configured plugs with wire jumpers in them that plugged into the jack to enable certain options. These became the original code plugs. Later on, more things were controlled by these code plugs, such as tone encode/decode selection.
    As radios became microprocessor controlled, the external code plugs moved inside the radio as programming information. The term has, unfortunately, remained with us, although there’s not much that still plugs in. The code plug contains the operating frequencies, tone selections, timeout values, system IDs, etc. In some instances, there’s even some parts of the program itself in the code plug which defines a radio’s personality. These days, the code plug is just a relatively small binary file that’s managed by the RSS program and transferred to or from the radio via several proprietary means. – Bob M.”
  • Talk Group “A talkgroup (TG) on the PRN system is like a channel on an analog radio. If you have your radio on one talkgroup, you will not hear a user on another talkgroup, even if they are on the same repeater.” – NCPRN.org
  • Channels
  • zone – A zone is a group of channels. Your radio supports up to 250 zones, with a maximum of 16 channels per zone.
  • Software Version – This refers to the version of the computer software that you use to update the radio from your computer (CPS programming software).
  • CPS programming software – the CS750 is really not programmable by keypad or is at least painful if you can. You need the CPS software that works on PC only systems.
  • RadiolD – “MY Radio ID” – The unique number you get signing up for digital. This identifies you on your digital system from the registration page for Digital Voice Services – http://register.ham-digital.net/
  • PTT ( PUSH-TO-TALK) Button
  • Firmware Updates
  • Firmware Version:
  • Boot Loader Version:

Understanding Talkgroups and Channels by example

It is important to understand that a DMR Repeater works differently from aAnalogge Repeaters:
“Your repeater has two channels, time slot 1 and time slot 2. They switch back and forth about 60 times a second. Time slot 2 is generally reserved for PRN. TS1 is shared among the talk groups your repeater is programmed for. If you want to talk on TAC310, key it up and your repeater carries that talk group for 10 minutes. If you want to clear that TG earlier, there’s a Clear Timeslot TG that will release the repeater. You can use Monitor All to listen to all the TGs that your repeater carries, whether they’re activated or not. Terminology can be confusing. With two TSs, your repeater can carry two conversations, one on TS1 and one on TS2” – Rob Schonk

For a number of the channels like TAC 310 on below you “key the channel and wait to hear someone talking. It won’t open the channel until the person talking unkeys. It is an on demand channel. After you wait there may be no one there you can talk. Come on DCI and I will talk to you.” WO3F.

“Some of the talk groups. Basically, they access different geographical areas. Southeast is no longer supported because of a dispute about whether it should be full time or user activated.

http://ncprn.net/?page_id=32

When you switch to a different channel, you won’t hear someone talking until their signal drops, and the other person starts talking. If you start talking immediately, it tells you the channel is busy. You should see a green led to indicate a busy channel.”

“There are LOTS of talk groups, but your local repeater can only handle 16, but in practice, generally handle 10 or less.” – Rob Schonk
An example of a series of Channels.  Look at the radios “Channels” on the CS750 with a club made “code plug”

  • Cary PRN (On all the time. Just push, wait for the tone and talk).
  • Cary Local (locally connected channel, this one is connected to Raleigh Local and a few others. Just push, wait for the tone and talk).
  • TAC 310 CA (North America, you will press the talk to activate the repeater, then wait and listen for activity then state your call sign. Eg. KI$CFS on TAC 310 Cary Repeater in N. Raleigh NC, mobile and monitoring. The repeater will time out after 10 min of no activity and that initial 1st press is required to start talking again).
  • TAC1 CA
  • DCI Bridge CA (World wide use. Activate in the same way at TAC 310 CA)
  • Southeast CA (Southeast USA, Activate in the same way at TAC 310 CA)
  • Echotest CA (Lets you hear yourself and the quality of your own signal quality).
  • Clr Timeslot CA
  • Monitor All CA (lets you monitor all of them is your radio is in scan mode to see if anyone is talking. You can’t talk on this channel).

    Great post, Martin! Thanks for sharing this info on DMR. I think it’s an area where more hams are fairly uninformed.

  3. KO4L Lloyd says:

    Thanks Martin, Great Site and info. My CS700 will be upgraded in July. Connect Systems is swamped with upgrade requests..
