My manual (MC2500 but MC2000 is the same) lists the cable part # as DDN6367. The pinout should be RJ11 to DB9: RJ11 pin 1 to DB9 pin 3 RJ11 pin 2 to DB9 pin 2 RJ11 pin 4 to DB 9 pin 5 The ones that I have built, I just get a DB9 female to RJ11 female adapter body, plug it appropriately internally an...

Turn the radio off, press the radio's PTT button, turn the radio on again while holding PTT, release PTT

Since the GM / Maxreac / 1225 radios only use Ground and Bus + from programming, it connects the unused Bus - line to a bias voltage in the RIB.

It has been a while since I looked at the RIB circuit in enough detail to worry about the why.

Take a look at the batlabs.com site.

You don't need a resistor. Just a jumper between pins 11 and 4 of the DB25.

I have not set up a CDM to channel steer in a long time, and I cannot find the reference material at the moment, but I seem to recall that the input logic is actually BCD, not HEX, hence the need for five pins.

Correct. With the Waris series, V1 firmware needs to initially be stepped up to V2. From V2 it can be jumped to any later version. You do not need a Smart RIB to upgrade firmware on the Waris series, just the dongle to ground the bootstrap line. It is nothing more than an adapter that allows you to ...

If it's an LS, did you look at the default repeaters under LS Trunking \ SIte?

Most carriers host SMS gateways that will let you send a text via email. For example, you can text a Verizon phone by emailing {10 digit cell number}@vtext.com, Sprint at: {10 digit cell number}@messaging.sprintpcs.com, AT&T at {10 digit cell number}@txt.att.com, T-Mobile at {10digit cell numer]...

Actually, the problem was that a channel with MDC and TPL actually used the DPL offset value, frequently resulting in the hum problem. The same thing applies to CSQ- If your baseband offset frequency is within about 20 Hz of the TPL tone, you will tend to get an RX audio hum. Since the default CSQ b...

The current iterations of XP and OS X are actually pretty good at managing multi-adapter configurations without the need for any manual routing configuration, with a few caveats: 1) The LAN connection(s) should have static IP addresses, with the gateway field left empty. 2) The LAN interface(s) can ...

As of the 3/11/2010 NPRM in 10-36 ( http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-10-36A1.pdf ), the FCC has removed the requirement for frequency coordination when the only change to a license is the addition of a narrow band emission designator. You can simply open an application in ULS, a...

You may also want to check the voltage to the radio. I have seen problems with CDMs where, when the supply voltage is on the low side, they decide to stay on, even when the ignition sense line loses power.

It covers the vent hole in the casing.

The X9000 probably has the most versatile and flexible scan function of any Motorola product. As usual, that can get you into trouble as well. When in scan, the X9000 will only receive modes that are in the list. If the current mode is not in the list, it will not be received during scan. Each mode ...

You are probably absolutely correct about pin 4 being active low only (I'm working without CPS in front of me at the moment), which does mean that it pulls to ground when it goes active. Connecting a speaker to pin 4 will not get you anything, except a reminder of what running DC through a speaker c...

External Alarm will work for QCII systems, as well as MDC. The Auxiliary Control outputs are MDC only. You can use the output to drive just about anything you want, with the proper interfacing. It is just a pin that can be programmed to either go to +12V (or 13.8V, etc.) or ground when activated. Ti...

Forgive my asking an obvious question but, if you are using a cable with a RIB, you are putting the flashing adapter between the RIB and the radio cable, not between the RIB and computer, correct?

The accessory connector function are defined in the Radio Configuration section of the CPS. There are a couple of ways to do it. The first is to configure a pin for External Alarm under the Accessory Pins tab. That pin will respond to calls to the radio's MDC ID. The specifics of the External Alarm ...

- If you are trying to flash the radio through the mic jack using the RIBless cable, are you using the "B" position on the flashing adapter switch, and hitting the power button twice in quick succession? - On the radio side of the flashing adapter, the B switch position should short pins 1...

Are you trying to flash the radio through the microphone jack, or the rear accessory connector?

Is the radio a one piece, or remote mount configuration?

Most ambulances have a park / neutral sense line easily available in the electrical panel. I always just use that. When the vehicle is in park, the repeater is on, what it is rolling it is off.

I will second that.

You can do what you want using the MRTI connector rather than the system connector. When setting the TX priority, the MRTI connector is treated as part of the local mic path. I am currently on the road without my programming computer, but the MRTI connector pin out is available in the backplane sect...

Are you able to reach the machines on the other subnet by IP address instead of machine name? Do you know what protocol is being used to resolve the computer names? (NetBOIS, WINS, DNS, etc.?) I have managed to pretty thoroughly avoid Vista, but some name resolution schemes, like NetBIOS, will not n...

You did not specify if you are trying to convert a mid or high power unit. For the mid power unit, the correct interconnect board is HLN6459. For the high power, it is HLN6574, and is considerably more expensive. There is also a "Y" cable, HKN6096, that breaks out the accessory connector f...

If you are looking for a free hex editor, you could also try XVI32.

RKG- You are absolutely correct. That's what I get for dashing off a reply on a quick pass through the office. The inputs are straight binary, not BCD. I'm sorry that I couldn't make the dinner in Boston. I'm still getting free drinks out of knowing which bodies of water make Manhattan an island...

The channel select pins on most /\/\ radios are, in fact, BCD. Most of my experience has been with CDMs, and they do it just fine.

Well, considering most Mac's don't have a serial port - you won't be programming any of the "old" stuff without USB adapters or some other solution. Thanks guys. Alex: There are ExpressCard serial cards available that are essentially the same as the PCMCIA serial cards- A real serial port...

OK- I now have almost enough laptops to make a new coffee table, and I will soon be adding a MacBook Pro to the pile. That does not, however, mean that I like having to drag around more than one at a time. What are people's experiences and recommendations regarding using Windows on a MacBook Pro for...

It appears that you are confusing the switched contact circuit with the coil circuit on the relay. Neither of the normally open contacts would be used in this application. The basic idea of the relay is that it is an electromechanical device in which a coil of wire acts as an electromagnet and pulls...

Here's another good option for you:

For better or for worse, our IT department has a knee-jerk aversion to anything that says Linksys on it. When I get back on my normal side of the globe, I should have a new box waiting for me which I am going to try loading with Debian and Safe Squid when I have some spare time. (Sorry Terry, I'm al...

Thank you guys. I think we are all pretty much on the same page. I had uninstalled all of my /\/\ titles, run CCleaner and reinstalled the CPS. I was still getting the same error. If I copy all of the .dll files that ProRadio.exe is looking for from "Program Files\Common Files\Motorola\RKD"...

OK- I have an uncooperative computer on my hands. I do not remember if the Professional Series CPS had worked previously on this particular machine, or if I had installed it and never used it. At any rate, when I install and try to run the Professional Series CPS I get an error message informing me ...

Have you looked at the purpose-built vehicular repeaters like the Pyramid SVRs or the Vertex VXR-1000? All of the "PAC-RT compatible" units have an automatic priority resolution scheme that will automatically activate another repeater if the primary unit leaves the scene or goes off the ai...

Correct, the RLN4781 will only work for the UHF and VHF radios. If you cut the back strap off, you can slip a low band in for a fixed installation, but it woud never stand up to mobile use. The DIN mount only fits the smaller portion of the actual radio chasis. The enlarged control head portion sits...

Thanks Terry. Here's the basic (simplified) story of the application: The network runs audio devices in a number of performance venues. The devices on the network are a mixture of standard Windows workstations running control and playback applications, and dedicated audio hardware running embedded p...

To all of the networking gurus: I am currently looking for a reasonably priced (under $1K) hardware or software solution for establishing strict controls on internet access from within a network. The goal is to keep the devices on the network generally isolated from the internet while still allowing...

Give this a try: 1- Unplug the front shield 2- In RSS, create a new Model 1 codeplug for the radio (correct band, secure, etc.) Do not change anything in the default codeplug. 3- Program the new Model 1 codeplug into the radio. 4- If the radio accepts the Model 1 codeplug, reconnect the front shield...

They have a product for just about any application, and their custom rack shelves for equipment mounting are absolutely first rate.

From Motorola your portable choices will be either the HT750 or HT1250, and the available splits will be either 29.7-42MHz or 35-50MHz.

With the battery back-up kit installed, the fan runs continuously. Without the revert kit, it operates as needed. It is, indeed the way of the beast.

It sounds like something got pretty well corrupted on your drive and / or registry I have the CPS installed in D:\Program Files\Motorola\1225 Series RSS and it runs like a champ. I can also routinely pull archives from project folders all over the place, so I don't think that the CPS is that inflexi...

What speed is the COM port on your computer running at? I have had some problems with CDMs bricking during firmware upgrades due to high serial port speeds. If you are using a RIB, you absolutely should not run above 19.2k. In theory a RIB-less cable can run at higher speeds, however, as a member of...

My thought would be to go for a Zetron Model 38A with the auxiliary relay option (don't forget the special MTR2000 interface kit). Interface the CDM750 to the MRTI connector, as Will suggested. Set the Zetron 38 up for two tone sets- one "normal" i.e. "A" in "A" out, an...

FWIW, there is a DIN mounting sleeve for the CDM mobiles. However, it only recesses the slimmer body of the radio chasis. The larger control head portion remains forward of the mounting surface.
