Figure 4-14 Serial communication type and DIP switch configuration. (PS110/410)
For more information about pin out of serial port and wiring diagram, please refer to Appendix 1
Connections section.
NOTE :
1. Please turn off the power of the Pro Series device before changing the position of DIP
switch in case of PS110/410. Changing the position of DIP switch while the power is on
may cause damage to the device.
(If the DIP switches are set incorrectly the PS110/410 will display "Invalid"for the UART
type on the UI as shown on Figure 4-15, which will hinder communications to the serial
port.)
2. In case of PS810, UART type can be changed by software through configuration only. So
PS810 does not have a DIP switch for changing UART type.
