Appendix A Serial Port Settings
The serial port COM5 on TPC-1260H is adjustable. It can be set to RS-
232, RS-422 or RS-485. This port is designed with auto data flow control
capability. In other words, the TPC-1260H can automatically detect the
data flow direction at this port when the two-wired RS-485 communica-
tion is activated.
A.1 Jumper Settings

Panel”->”System”->”Device Manager”->”PCI Communication Port
(COM5)”->”Settings” as the Figure A.2.
