Home E38/E39/E52/E53 E46 DC DRIVER
10 channel PWM driver  
Driver includes 10 autonomous power outputs with a total carrying capacity up to 48A. Each channel can deliver up to 8A. The maximum voltage is 30V - recommended 24V (Ideally 48A x 30V = 1440 W. Pulse-width output offers three frequency options (1.5kHz, 5.8kHz a 23.5kHz), further slight possibility tuning in ten steps (to eliminate any interference when using more modules and one power supply). Module works with 256 (8bit) input values of power and 1024 (10bit) output. There are three gamma correction table (1.0, 1.6 a 2.2). PWM frequency, tuning and gamma correction are set along the entire module. Input is a standard RS232 (impedance > 10kOhms) and offers six possible communication speeds (600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600 baud).
Configurations commands (Accepted by module with SETUP button hold)
Default values are underlined
           
VHL H – gamma correction <0 - 2> 0 = 1.0 1 = 1.6 2 = 2.2
  L – comm speed <0 - 9> 0 = 600 1 = 1200 2 = 2400
      3 = 4800 4 = 9600 5 = 14400
      6 = 19200 7 = 28800 8=38400
      9 = 57600    
If comm speed value is unknown, you can send V14 command at all speeds. After this operation, the module will definitely set at 9600 baud and gamma correction 1.6.

If SETUP is hold when powering on, module will be communicating on 9600 baud (This speed will be NOT stored). Only command stores comm speed and gamma correction.

address FF is broadcast (Common to all modules)

WHL H – tuning <0 - 9> 0 = basic 1 = -0.05% 9= -0.45%
  L – frequency <0 - 2> 0 = 1.5 kHz 1 = 5.8 kHz 2 = 23.5 kHz
           
XHL HL – address <00 - FE>      
           
Example (for default settings) V14 … W00 … X00 Each command must be sent separately!

Saving to flash takes 4ms followed by automatically reset. Then the module is ready for the next command.
