Commands and Parameters 

 

INI Command

 

Description

 

ltm-setup-rev=x 

This keyword is set by the configuration manager to indicate the last time the file was updated. 

 

 

product-family=x 

The “product-family=2” must be set for eSynC products supporting battery modulation. 

 
The permitted range is 1 to 2. The value 1 is used for SimulCharge products (such as eSTS). 
The default is 2. 
 

btty-protection-type=x 

The “btty-protection-type” keyword selects the battery protection mechanism to be used. The options 
are 1 or 2 based on the mobile device being used. 
 
The selection used must match the mobile device capabilities. Mobile devices may only implement a 
sub-set of the USB-C PD specification, which requires LAVA test each model to verify the level of 
compatibility.  
 
eSynC Mk1 products only the “btty-protection-type=1”. 
eSynC Mk2 products support both “btty-protection-type=1” and “btty-protection-type=2”. 
 
Using “btty-protection-type=2” with an eSynC Mk1 results in the device charging to 100%. 

board-type=x

 

 

The “board-type” keyword 

is not used with eSynC

 products. 

With “product-type=1” set, the “board-type” keyword is ignored and the “btty-protection-type” 
keyword is used to define the battery protection type.  

 

 

btty-upper-threshold=x

 

 

The standard upper limit for battery charging as a percentage. 
The permitted range is 20 to 100. 
The default is 75.

 

btty-lower-threshold=x

 

 

The standard lower limit for battery charging as a percentage. 
The permitted range is 1 to 100. 
The default is 45.

 

btty-cycle-limit-on-start=x

 

 

The number of charge cycles after startup before a "full" charge cycle is forced. 
For a "full" charge cycle the btty-cycle-lower-threshold and btty-cycle-upper-threshold are used. 
The permitted range is 0 to 100. A value of 1 is treated as 2. 
The default is 2.

 

btty-cycle-limit=x

 

 

The number of charge cycles before a "full" charge cycle is used. 
For a "full" charge cycle the btty-cycle-lower-threshold and btty-cycle-upper-threshold are used. 
The permitted range is 1 to 9999. Values less than 4 are treated as 4. 
The default is 50.

 

no-btty-modulation=x

 

 

This command can be used to disable the battery modulation. The LTM application continues to run 
and provide other extended features such as network recover and screen brightness management. 
A “1” results in: no battery modulation and all battery thresholds are internally set to 100. 
A “0” permits battery modulation. 
Disabling battery modulation is not recommended. The ability is present for internal testing. 
The permitted range is 0 to 1. 
The default is 0. Sorry for the use of reverse logic.

 

 

 

permit-ethernet=x

 

This command is used to enable the Ethernet related features of LTM. 
The permitted range is 0 to 1. A 1 permits the Ethernet features. A 0 disables the Ethernet features. 
The default is 1.

 

dhcp-recovery=x

 

 

A dhcp-recovery value of 1 or 2 enables the Network/DHCP Recovery mechanism. 
When the network connection is lacking for approximately 1 minute, a network reset is attempted. 
A value of 0 disables the mechanism. 
The permitted range is 0 to 2. The default is 1. 
 
A dhcp-recovery value of 1 results in subsequent recovery attempts taking place after 2, 3, 5, and then 8 
minutes. After the first four recovery attempts, then subsequent attempts are every 8 minutes.  
 
A dhcp-recovery value of 2 results in subsequent recovery attempts taking place every 2 minutes.
