Section 3: Operation- Bypass Modes and Switch Location
NOTE! Before depressing the BYPASS switch, the gain settings on all amplifiers connected to the CM16a must be reduced to a safe level. This is because the CM16a’s “Level Control” will be reset to 0 dB with the BYPASS. Amplifiers could be at maximum output level if the amplifier gain controls are not turned down.
BYPASS MODE #1
HOW TO put the CM16a into BYPASS MODE #1:
1- Turn the CM16a on and wait 5 to 10 seconds for the
2- Depress the BYPASS switch (use a paperclip or similar item) and keep it depressed for at least 5 seconds.
3- The two steps above must be completed within 60 seconds from
BYPASS MODE #2 (SAFE MODE): Use if the CM16a becomes inoperable (or behaves in completely unexpected ways)
after uploading a new application file (TFTP file transfer).
If the CM16a operates in an unexpected way or is not responding to any communications after a new application file is uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the CM16a that will enable you to communicate with it.
HOW TO put the CM16a into BYPASS MODE #2:
1- Turn off the power to the CM16a using the front panel power switch.
2- Depress the BYPASS switch (use a paperclip or similar item) and keep it depressed while turning the power on again.
3- The CM16a is now in “safe mode”. You may release the BYPASS switch.
You will now be able to
Location of BYPASS switch: The front panel has a small access hole on the right side about 12mm (1/2”) to the right from the PORT H LED. It is NOT LABELED to help prevent accidental use. This is the BYPASS mode switch. To return to normal operation, simply reestablish computer communications via the network or
