This setpoint can be used to add extra AT commands at the end of the 
initialization sequence of the modem connected to the COM2 port. The 
command can be entered with as well as without the "AT" prefix, are 
separated with semicolon and maximal length is 31 characters. 
The setpoint can't be modified via the IG-NT built-in terminal. 
Using a modem at the COM2 port is not supported since the hardware 
version 2.0. For modem use the COM1 port instead. 
 
12.2.3.10  Setpoint: RS485(1) conv. 
This setpoint selects function of the built-in RS485(1) converter. 
 
The communication port COM1 is redirected to the 
integrated RS485(1) converter. The RS232(1) connector 
has no function and the external display interface is not 
available.  
The communication port COM1 is present at the RS232(1) 
connector and the RS485(1) connector is used for the 
external display interface.  
 
NOTE:  
The redirection is applied only for DIRECT, MODBUS and ECU-LINK modes. 
See the setpoint RS232(1) mode.  
 
NOTE:  
This setpoint must be set to DISABLED at controllers that do not have 
internal display. i.e. InteliVision-5 or InteliVision-8 is connected to the 
RS485(1) terminals.
