Telex / Vega IP-223 with a CDM-1250 programming issues

[jetskibum]

Is anyone familar with the IP-223? I have it installed and I can get it to receive from the CDM-1250, however, it wont TX.

I am not sure what pins 4,6,8,12 & 14 should be programmed too. Since the CDM allows you to change the pin functions.

The IP-223 says that
4 - COR
6 - Digital 0
8 - Digital 1
12 - Digital 2
14 - Digital 3

Checking all the options for the CDM there is nothing that reflects those options choices.

All the jumpers on the ip-223 are set correctly.

You have to go into the options on the IP-223 and set it to use the PTT relay on key.

here's a chart for wiring:

CDM___IP-223___FUNCTION
2______25______TX AUDIO
3______14______PTT
6______20______PL/CSQ DETECT (IN CDM PROGRAMMING)
7______12,13,7,2_GROUND
11_____24______RX AUDIO

-You only need PL/CSQ detect if you are requring the IP-223 to use it in the options. if you dont use it the IP-223 will run in VOX, which is generally reliable, but I generally use COR if I have it available as it's even more reliable than VOX.

-set all of your jumpers for TX and RX audio to high impedance, unbalanced.

-This setup is using the PTT relay in the IP-223 to key the CDM radio. one of the pins on the IP-223 (pin 2) is the common on the PTT relay. the output is the N.O. (normally open, pin 14)

You could also use the digital PTT (Digital out 5, pin 23) but I always use the PTT relay. You may have an issue with the line not pulled low enough to actually key the radio. I go with the relay for PTT because I know I am dealing with a good ground, and not a digital output potentially sitting just above the trip point for the PTT line on the radio.

This should get the radio running at least on one channel. If you're looking to do channel steering (you may be because of using the other digital outputs) PM me and I'll walk you through how to set the radio up to do it.

I've set up quite a few on wireline (2W and 4W) and local control with channel steering.

on the CDM #6, I think that is supposed to be #4 as I do not see the PL CSQ option for #6.

I can get the radio to RX however, it will not TX through the IP223. The IP223 says it is TX'ing, though nothing happens with the radio.

The jumpers for the IP-223 are set for a mobile radio and it is configured for a radio also. The cable was purchased from the Factory for a CDM-1250.

I have tried several different options in the CDM accessory pins, however, I still cannot get it to TX.

The radio does TX normally.

Are you using the cable that was supplied with the IP-223? If so can you tells us what colours are going to what pins on the 16pin option plug?

If I remember correctly I used light green for ground, red/white for PTT, green/white for COR, gray/black for RX audio, black/white for TX audio.

IP-223.................CDM-1250

light green.........................Pin 7
red/white...........................pin 3
green/white.......................pin 4 (pin 8 for non-CDM's)
gray/black..........................pin 11
black/white........................pin 2

Be sure to program the CDM's accessory configuration for RX filtered audio, TX Ext MIC audio, and Pin 4 CSQ/PL/Talkgroup Detect active low or high and choose the same in the IP-223 configuration page under Per line set up.

[jetskibum]

I am using a cable from the factory for the IP-223 and CDM1250, so it was pre-made by the factory. It was not the half a cable that comes with the IP223.

I have both configured as you state, however, I only get RX and though the IP-223 says it is TX, the radio is not.

[ve3nsv]

Maybe try connecting pin 3 & pin 7 on the acc connector together with a test plug and see if the CDM will transmit, if not you have radio issues.

Also test between the light green and red/white wire with an ohm metre to see if it is going low when transmitting through the IP-223 (I'm assuming through C-Soft?)

Are you sure you are transmitting on the proper port on the IP-223? Are you using C-Soft to transmit with? Are you sure you have the proper ports set and aren't accidently transmitting on Port 2 on the IP-223?

We did have an IP-223 that didn't recognise COR on port 2 a few weeks back, but for the most part they are pretty reliable.

[jetskibum]

Yes I am using C-soft to TX, though I also have a handset to TX from the front of the IP-223.

I tested the 3 and 7 pin and it made the radio TX.

I noticed in some paperwork from telex is says that jumper R377 "Solder bridge the pads together" Does that need to be done? as I dont remember in the training class that it was needed.

[jetskibum]

we tested the light green and red & white with the ohm meter and ther was no change

[ve3nsv]

Yes both 377 and 381 (If you plan on using Port 2) will need to be bridged together. Do you have the page in the manual that shows all the jumper settings for the CDM radios? I have always set my IP-223's according to jumper settings on that page and never had any problems.

According to the manual, this wil be your problem.

3.2.6 PTT Connection
Connect the radio PTT circuit to the PTT relay contact terminals of the panel. This can be done on the
rear DB25. Usually the common of the relay contact switch is grounded and the normally open contact
connects to the PTT input. It is also possible to ground the common of the relay internal to the unit by
bridging R377 (line 1) and R381 (Line 2) with a piece of wire and soldered closed. Note: Rev A boards
must have the common lead grounded at the DB25 connector.

[jetskibum]

Right now I am just using Port 1 (radio 1) connector.

All the jumpers are set correctly according to the manual for the CDM Radios.

I also bridged the R377, though there is still no TX

[ve3nsv]

Did you bridge 381 also, given 381's location on the circuit board it may very well control port 1 (radio 1), they are easy enough to unbridge if you need to for another application.

I've never had to bridge them before and I've put quite a few of these in at this point.

IP-223 setup is schooling me.................I am using several different PM400 and CM300 radios. The IP-223 is always showing RX mode (unless I change is to COR Active High in the 223). The issue seems to be that the PM400 and CM300 seem to have problems on thier pin 4 for COR. I am getting 7.75vdc in "low" and 11.45vdc in "high". This is measured in reference to pin 7 "grnd". This is happening with several radios including ones straight out of the box. WTF, over? (you know you are frusterated when you start to question your equipment, using different service monitors, VOMs, power supplies, etc!!!). Thank you, FatBoy.

The above 223 rollout is due to ripping out a bunch of Critical RF Sitecast VOIP devices due to poor reliability and poor performance. It is really biting me in the butt for using Critical RF's products. If anyone is reading this, their stuff is not ready for prime time. We have several systems that will need to replaced. FatBoy

Setting up one of the IP223 boxes software wise is a learning experience. There are a number of issues that you need to keep track of. One of them is the IP address of the box. This is needed so the C Soft running on the computer can talk with it. i am good with radios and it kicked my butt the first time I played with it. I will say that unless you use the boxes and the software all the time, you will forget it. Better take notes and write allot of them down.

If the IP223 never shows transmit when you try to key it, it will never key the radio. You might just want to call the tech service number and have them walk you through the setup. Once you get it working, don't forget that you will have to set the transmit audio levels. If your doing paging, it is even more important to get the audio levels correct. It will probably take a service monitor and a couple of people to play with the system to get the adjustments where they need to be. Make sure the paging tones are not into compression.

I'll see if I can find a PM400 or CM300 to play with to see where mine land with their COR. That's not good if they won't go close to ground. Your IP223 will not correctly detect a hardware receive condition. VOX is a possibility, but VOX always a second best choice no matter who makes it. In the mean time, check your J8 (line 1) or J30 (line 2) to see if they are set for 5V, 12V, or null.

[Bill_G]

I don't have a radio to play with, but I think I know where one is. Will be in touch.

[FatBoy]

1 pm400 and 3 cm300's had the following on their COR pin (pin 4).
In "low" mode
COR active 11.45vdc
COR inactive 7.25 vdc

In "high" mode
COR active 7.25vdc
COR inactive 11.45vdc
voltage referenced to both pin 7 (ground) and actual chassis ground

wierd, maybe I need a firmware update or a call to Moto tech support. By the way, the 223's seem to work very well in VOX mode. FatBoy

[Bill_G]

Okay. That's horrible COR line performance. I wonder what's going on in the radio. If VOX is satisfactory, then you're good to go. It always falsed too often for my tastes. If you have any troubles with the config, let us know.

[FatBoy]

VOX or "LAM" as Telex calls it, is very sensitive. One unit is ok at -40 on one channel at one site, but needs -35/-30 at another. Was able to overcome with changing between filered or flat audio, then adjusting the LAM sensitivity, then adjusting audio level going from radio. Going to spec CDMs only moving forward.............. It greatly concerns me that there areso few people in this geographical area that seem to want to deal with these problems. Why do these people think I have all of the answers? FatBoy
