The following paragraphs describe the operating procedures for a CMM5 Injector in standalone mode (Controller not present).

**Note** : When a Controller is present the Injector operations can be run entirely from the Controller GUI interface. (Refer to the CMM5 Controller Operation section for details.)

Perform the following steps to read the current parameter values from the Injector, and modify them if desired:

&nbsp;

| 

**Step**

 | 

**Action**

 |
| 

1

 | 

Run the TeraTerm terminal emulator and start a serial session to the Injector COM port.

 |
| 

2

 | 

Execute the following query command to read the Injector parameters:

**&0p**

 |
| 

3

 | 

The Injector responds with the current parameter settings as shown below:

- There are 20 parameters in total, of which the first 8 are settable by the user
- Three values are shown on each row, representing the current parameter setting, the minimum value, and the maximum value in the range respectively
- Parameters 1 through 4 represent the power states for each of the 4 ODU ports

  - +0001 = enabled
  - +0000 = disabled

- Parameters 5 through 8 represent the sync states for the 4 ODU ports

  - +0001 = enabled
  - +0000 = disabled

To enable power on one of the Injector ports, use the following command format:

**&0p##,0001**

Where ## is in the range 01 through 04, representing ports 1 through 4 respectively

Will these commands work remotely through SSH with Putty?
