Communication Ports
The SF-2110 provides two 9-pin female Positronic 
connector communication ports labeled Port A and 
Port B located at the back of the sensor, as shown in 
Figure 9. Each conforms to the EIA RS232 standard 
with data rates from 4.8 to 115.2Kbps. The connector 
pin-outs are described in Table 4A and 5B. The 
supplied interface data cable (P/N 94-310260-
3006LF) is constructed as described in Figure 8. The 
SF-2110 is configured as a DCE device. Laptop and 
desktop computers are configured as DTE devices, 
therefore a straight-through cable provides proper 
connectivity (PC TXD pin 2 connects to SF-2110 RXD 
pin 2). 
New models of the SF-2110 provide Bluetooth 
wireless connectivity within a range of 10 meters (32 
feet). Only SF-2110 sensors with the Bluetooth icon 
on the front indicator panel are Bluetooth capable 
(see Figure 11). The Bluetooth module contains 
Bluetooth-certified components. The data rate for 
Bluetooth communications is 230.4Kbps.
