Default M7300 Conversion to Remote Mount Problem

I have a CS7000 with an M7300 that I use to monitor a local Phase II system. It works great, but I decided to convert the "dash-mount" radio inside the CS7000 to a remote version so I could mount it in my truck. I've done this several times with XG100M mobiles and I've never had a problem. This time however, the radio comes on, works for about 5 seconds, then displays the firmware, then reboots. It does this is continuously until power is removed. I suspect the CAN cable may be bad. Does anyone have any suggestions before I tear everything apart? I did check to make sure that the 3 flex cables were fully seated inside the control head. Power is good to the red & white wires on the control head and the MRU has power to the red wire only, per the install manual.

What would make the radio constantly reboot?

Have you tried to reprogram?

Not a personality programming issue. Ran into this issue several years ago. You need to plug in the CH to hyperterminal and essentially tell it, that is is now a remote head. The easiest way I've found to do it, is assemble the head onto the remote housing, power it up by itself and plug into it via the serial port. From my notes here are the instructions:

Use this procedure to change the control head’s model information character.
The model information character is the sixth (6th) character in the head’s
12-character EID:
1. If a CAN cable is connected to the control head, disconnect it. The head
cannot be communicating with a radio.

2. Turn the control head off by rotating its on/off/volume control fully
counterclockwise to the off (detent) position.

3. Set a regulated-output DC power supply to 13.6 Vdc and connect it to the
control head’s DC power input connector using DC Power Cable
CA-012365-001 or CA-012616-001.

4. While holding the control head’s “C” preset button fully depressed, turn
the head on by rotating its on/off/volume control clockwise out of the
detent position. When it powers-up, it will indicate “NO MRU” in the
display. Disregard this indication. The head’s test command mode is now
enabled.

5. Using CH-721 Serial Programming Cable CA-104861 (or equivalent),
connect the Personal Computer’s (PC’s) serial port to the DB-9 serial port
connector on the rear panel of the CH-721. If the PC is not equipped with
a DB-9 serial port connector, the use of a suitable adapter is required,
such as USB-to-RS-232 Adapter Cable CN24741-0001.

6. At the PC, start the terminal emulation software such as Windows
HyperTerminal.

7. Configure the terminal emulation software for the respective serial
communication port (e.g., COM1) at 19200 bps, 8 data bits, 1 stop bit, no
parity, and no flow control.

8. Set the terminal emulation software’s function, arrow, and control keys to
act as terminal keys. For HyperTerminal, this is accomplished via the
respective serial port’s Properties dialog box (Settings tab), as illustrated
in Figure 5-3.

9. Set the terminal emulation software for TTY (teletype) emulation. For
HyperTerminal, this is accomplished via the respective serial port’s
Properties dialog box (Settings tab), as illustrated by the left-most dialog
box in Figure 5-3

10. Set the terminal emulation software to echo typed characters locally. For
HyperTerminal, this is accomplished via the respective serial port’s
Properties dialog box (and Settings tab), and ASCII Setup… button, as
illustrated by the right-most dialog box in Figure 5-3.
Figure 5-3: Configuring the Terminal Emulation Software
(e.g., HyperTerminal)

11. While in the terminal emulation software, enable “Caps Lock” by
pressing the respective key on the PC’s keyboard. The control head’s test
command mode only recognizes capital (upper-case) letters.

12. Type the following command to send it to the control head. This is the
“shown EID” command. <Ctrl B> means to hold the keyboard’s “Ctrl”
key down while typing the "B" key. Likewise, <Ctrl C> means to hold the
keyboard’s “Ctrl” key down while typing the "C" key. The space between
the “W” and the “E” must be included, and all letters must be in upper
case.
<Ctrl B>CH-SHW EID<Ctrl C>
The control head will respond with its 12-character EID string, as illustrated in
Figure 5-4. The sixth character in this EID string is the control head’s model
information character that must be changed in a subsequent step. The other
characters within this string cannot be changed.
Quote:
Table 5-1: Control Head’s Model Information Character
Definitions (6th Character in the 12-Character EID String)
6th
CHARACTER CONTROL HEAD MODEL
5 Front-Mount System Model Control Head
6 Remote-Mount System Model Control Head
7 Front-Mount Scan Model Control Head
8 Remote-Mount Scan Model Control Head

13. Select only the twelve reported EID characters and copy them to the
Windows clipboard.

14. Open a Windows Notepad session and paste the 12-character EID string
into Notepad.

15. Using Table 5-1 as a guide, determine the proper new character for the
control head conversion, for example, if converting a System model
control head from a remote-mount to a front-mount, the correct new
character is 5.

16. In Notepad, change the sixth character of the 12-character EID string to
the proper character. The other characters within this string cannot be
changed!

17. Copy only the 12-character EID string to the Windows clipboard (with
the new 6th character).

18. Within the terminal emulation software, type the following command to
send it to the control head. The space between the “D” and the “S” must
be included, and all letters must be in upper case.
<Ctrl B>CH-LOD SFM<Ctrl C>
<Ctrl B> means to hold the keyboard’s “Ctrl”
key down while pressing the "B" key. Likewise,
<Ctrl C> means to hold the keyboard’s “Ctrl”
key down while pressing the "C" key, then
release both keys before pressing the key for the
next character.

19. Within the terminal emulation software, type the following command to
send it to the control head. This is the “clear EID” command. The space
between the “R” and the “E” must be included, and all letters must be in
upper case.
<Ctrl B>CH-CLR EID<Ctrl C>
The control head will respond with a cleared EID (all 12 characters set to
“F”), as illustrated in Figure 5-5.
Figure 5-5: Clearing the Control Head’s EID (Example)

20. Send the revised EID to the control head by sending it the following
command. Spaces are significant, and “Revised_EID_Characters” is
use a paste function within the terminal emulation software to enter the
EID, before typing the <Ctrl C>:
<Ctrl B>CH-SET EID Revised_EID_Characters<Ctrl C>
CAUTION
Verify the entered string is correct before sending the
<Ctrl C> to the control head. If the string is not correct, press
the Backspace key until the string is erased, type or paste in
the correct string, and then press <Ctrl C>.
An example is shown in the following figure:
Figure 5-6: Sending the Revised EID to the Control Head (Example)
The control head’s EID is now revised to match the new
mounting configuration.

21. Disconnect DC power from the control head, and then disconnect the
serial cable.

22. If performing a front-mount to a remote-mount conversion, connect the radio
to the control head via the CAN link, power-up both units, and verify basic
control head operation. Be sure to terminate the radio’s antenna port with
an appropriate antenna or 50-ohm load.
If performing a remote-mount to a front-mount conversion, continue with the
hardware conversion procedure presented in Section 5.1.2.

Worked like a champ. Changed it from a 5 to a 6 and all is well. Thank you very much!
