4.1.2 USB Connection 

(6EP1931-2DC42,.-2EC42, -2FC42 and 6EP1933-2EC41, -2EC51, -2NC01, -2NC11) 
 
The prerequisite for communication via USB is a properly installed driver. Installation instructions can be found 
here:

. 

 

- 

Output of the signal states every 75ms 

 20%, 29ms 

 20% data output, 46ms 

 20% break 

- 

The USB interface corresponds to Specification 2.0, but communication takes place only at full speed, i.e. 
12Mbps. 

- 

The optional USB module is supplied with +5V from the DC USP ("self-powered"). 

 

It is connected to the PC by means of a four-wire, screened USB cable with a USB Series "A" plug on the PC 
side and a USB Series "B" plug on the SITOP DC UPS module side with a maximum length of 5m. 
 
Pin 1: VBUS (+4.40V to +5.25V DC), transmit data to Pin2 (D-) and Pin 3 (D+), Pin 4: GND 
 
 

4.2 Transmit Data of the SITOP DC UPS Module

In case of a defective battery, the "Alarm/Buffer Ready" signal changes at a frequency of 0.25Hz and a 
keying ratio of 0.5. 
 

Table 10: Transmit Data of SITOP DC UPS Module 

 
 

4.3 Receive Data of the SITOP DC UPS Module 
 

The SITOP DC UPS module can react to a remote signal transmitted by the PC. Prerequisite: DIP Switch 1 of 
the lower switch panel is at Off (right). 

 

4.3.1 Serial Connection 

(6EP1931-2DC31 and 6EP1931-2EC31) 

 

A bit pattern is sent from the PC to Pin 7 (Pin 4 in case of a 25-pole plug/socket) according to Diagram 1. When 
this signal is received and the interface is closed by the operating system (last edge from high to low), the 
buffering time set using DIP Switches 2 through 7 of the lower switch panel is started and the output voltage is 
shut off when the buffering time is up. 
 
Note: If DIP Switch 8 of the lower switch panel is set to On (left), the output voltage will be disconnected for 
approximately 5s according to the set buffering time even if the network returns in the meantime. (This enables 
an automatic restart of the industrial PC).
