board.  Do not pull on the flex circuit to remove the flex connector from 
TS4000 because this will damage the flex circuit. 

„ 

Lift the body of the serial port 2 connector up and on top of the radio module 
circuit board to move the flex circuit away from the jumper block.  With the 
radio flex connector on the right side of the jumper block, the jumper block 
will be oriented as shown above with pin 1 located at the bottom right corner.   

 
To enable power on pin 9 (RI - Ring Indicator) of serial port 1, locate the jumpers 
across pins 17 and 18, and pins 19 and 20.  Remove these two jumpers using 
the small needle-nose pliers or tweezers and reinstall the jumpers across pins 17 
and 19, and pins 18 and 20, as shown below. 

 

 

To enable power on pin 4 (DTR – Data Terminal Ready) of serial port 1, locate 
the jumpers across pins 13 and 15, and pins 17 and 18.  Remove these two 
jumpers using the small needle-nose pliers or tweezers and reinstall the jumpers 
across pins 15 and 17, and pins 16 and 18, as shown below.        
        
Caution: The use of the DTR pin for a DC power input connection is non-
standard.  Therefore the TS4000 serial port must not be connected to a 
standard serial host device that drives the DTR pin (i.e. a PC).  This could 
result in the power supply voltage of the TS4000 being shorted to the DTR output 
of the host serial port, which could damage the host device.  Therefore, when 
connecting the TS4000 to a PC for configuration, make sure that the cable does 
not have the DTR (pin 4) line connected.
