Quick Start Guide for TWR-SER2
Serial Settings
Refer to these settings to configure the
multiple serial connections.
?  Serial-to-USB —The TWR-SER2
will be connected to a host PC using 
J5 (mini B). Use driver included on 
DVD to install the virtual COM port on 
the host PC. 
  J7 pins 1-2, 3-4 should be shunted
?  RS232 DB9 —The TWR-SER2 will be
connected to a host PC using the 
onboard DB9 connector.
  J1 pins 2-3 should be shunted
  J2 pins 2-3 should be shunted
  J13 pins 1-2 should be shunted
?  RS485 DB9 —The TWR-SER2 will be
connected to a host PC using the 
onboard DB9 connector.
  J1 pins 1-2 should be shunted
  J2 pins 1-2 should be shunted
  J13 pins 2-3 should be shunted
  Loopback settings can be 
configured using J11
TOWER SYSTEM
?  RS232 Headers —The TWR-SER2
will be connected a host PC using 
the required adapter cable(s) 
connected to J19 and/or J20.
  J22 pins 1-2, 3-4 should be 
shunted to UART2 (J19) 
  J22 pins 5-6, 7-8 should be 
shunted if using RTS/CTS flow 
control on UART2 (J19)
  J23 pins 1-2, 3-4 should be 
shunted to UART3 (J20)
  J23 pins 5-6, 7-8 should be 
shunted if using RTS/CTS flow 
control on UART3 (J20)
CAN Settings
Refer to these settings to enable the
connection to the CAN Transceiver.  
The TWR-SER2 will be connected to
a CAN device using J3. Refer to the 
TWR-SER2 User Manual for header 
pinout details.
?  J4 pins 3-4, 5-6 should be connected
?  J4 pins 1-2 can be connected to 
enable control of “Silent Mode”
