User manual for regulated current source SZP-73

”bAud”

  - this parameter determines RS-485 interface baud rate. It can be set to one of 8 

possible values:  

”1.2”

,  

”2.4”

,  

”4.8”,

 

”9.6”

,  

”19.2”

,  

”38.4”

,

”57.6”

,

”115.2”

, which 

respond to the baud rates of 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 

115200 bit/s respectively.

”mbAc”

- this parameter sets the access to the configuration registers of the device. 

Possible values:

”on”

- configuration registers can be set via  RS-485 interface,

”oFF”

- configuration registers can not be set via  RS-485 interface.

”rESP”

-  this parameter defines minimal (additional) delay between the Modbus message 

and   the   answer   of   the   device   (received   and   sent   via   RS-485   interface).   This 

additional delay allows the device to work with poor RS-converters which do not 

works properly on baud rates higher than 19200. This parameter can be set to one 

of values:

”Std”

- answer as quick as possible, no additional delay

” 10c”
” 20c”
” 50c”
”100c”
”200c”

- answer delayed of 10, 20,   50, 100 of 200 chars respectively, where 

one character time depends on selected baud rate

In the most cases parameter  

”rESP”

  should be set to  

”Std”  

(no additional delay). 

Unfortunately   for   some   third   party   RS-converters  

”rESP”

  should   be   adjusted 

experimentally. Table 7.1 contains most frequently used values.

”Edit”

  

 paramet

  

er

  

This parameter allows to change the edition mode of numerical parameters:

”dig”

- the change to “by digit” mode,

”Slid”

- slide change mode.

7.3.11. 

  

”dEFS”

  

 parameter

  

 This setting allows to restore the factory settings of the device. To get the access  to this 

option special password is required: „5465”, next the device displays acknowledge question 

„SEt?”

. Press

 

 

[ENTER] 

to acknowledge the restoring of factory settings or 

[ESC]

 to cancel.

7.3.12. 

  

”SErv” menu

  

This   menu   contains   the   parameters   for   authorized   service   only.   To   enter   this   menu 

proper service password must be entered. Improper settings can causes of damage of the 

device.
