4. H. S. CAENET OPERATION 

 
The Model N568B/LC is provided with an H. S. CAENET node through which it can be controlled by 
the following H. S. CAENET Controllers: 

 

Mod. A250

  

- H. S. CAENET Manual Controller; 

Mod. V288

  

- H. S. CAENET VME Controller; 

Mod. C117B 

- H. S. CAENET CAMAC Controller; 

Mod. A303

  

- H. S. CAENET PC Controller. 

 

NOTE: the address number of the N568B/LC (Station #) must be the 
only one in the line in which you wish to insert the module. Due to high 
transmission speed of the data in line it is necessary to terminate this 
line on a 50 

Ω

 impedance at the end to avoid reflections. 

 

Via H. S. CAENET it is possible to select the desired output channel, that will thus provide the same 
input signal. 

4.1  USING THE H. S. CAENET MANUAL CONTROLLER 

 
The Mod. N568B/LC can be controlled remotely via VME through the Mod. A250 H. S. CAENET 
Manual Controller. The Mod. A250 has been designed to control a H. S. CAENET node via 50 

Ω

 

coaxial cable. 
 
The sequence of display pages in the Manual Controller is not exactly as in the suggested first-
settings procedure (see § 3.2), but after a first setting is performed, the first page appearing in the 
Display is the Gain setting page, which is the most frequently accessed page. 
 
In order to use the Manual Controller, the User must connect it to the N568B/LC, using a 50 Ohm 
coaxial cable into the "H. S. CAENET IN/OUT" connectors of the N568B/LC; the supply of the Manual 
Controller is provided from the N568B/LC front panel via suitable cable (RCA connectors) supplied by 
CAEN with the Manual Controller. Once supplied, the Manual Controller's display will appear as 
follows: 
 

CAEN A250  1.0  

Select Cr.  **    

 

 
where 1.0 is the Firmware release version of the Controller itself. 
 
Type the address number of the module, previously set via thumb-wheel switch on the front panel, 
and confirm the choice with the key "#". The display will show: 
 

AA   Software    

N568 Version x.x

 

 
where AA is the selected address number. The version number is the N568B/LC Firmware version. 
By pressing the "PAGE" key, the display will appear as follows:
