How to control HV LeCroy 1442

(last update on 9/6/1999 by K.Kawagoe)

LeCroy 1442 is currently controlled from an ASCII terminal attached to it. The simple commands that I know are the following:

Select the HV Unit;
```
M01(CR)
```
Turn on HV
```
ON(CR)
```
Turn off HV
```
OFF(CR)
```
Read the current setting of channel 25;
```
R E C25(CR)
```
Read the current setting of 10 channels, starting from 15;
```
R E C25DO10(CR)
```
Set (write) channel 25 to be -1400V;
```
W -1400 C25(CR)
```
Set (write) 10 channels starting from 25 to be -1400V;
```
W -1400 C25DO10(CR)
```
Copy "DEMAND" into "BACKUP" buffers;
```
CO C25(CR)
```
Swap "DEMAND" and "BACKUP" buffers;
```
SW C25(CR)
```

NOTE: HV channel starts from 0 (zero), not from 1 (one) !!
