Connection Setting
The RS232 connection must use the following settings:
Baud Rate
38400
The display's RS232 connector is wired in the straight through configuration, with the pinout as
follows:
● Pin 2: Tx out
● Pin 3: Rx in
● Pin 5: Ground
● Shell: Ground
● All other pins: No connect
By default, RS232 functionality is disabled in the display. To enable RS232 functionality, change the
display's RS232C Control setting to On. For details, refer to the More Features menu in the Planar
HB Series Huddle Board User Manual.
Note: RS232 commands over LAN can be achieved by opening a TCP connection on Port 4660 to
the display.
Note: The Power Management setting in the OSD controls the behavior of LAN commands in
standby. Reference the Planar HB Series Huddle Board User Manual for more details.
● If Power Management is set to Standby Mode, LAN support is disabled in standby.
● If Power Management is set to Networked Standby Mode, the display will only recognize a
Wake-on-LAN packet in standby. Use the Wake-on-LAN packet to power on the display,
instead of the regular Power On serial command.
● If Power Management is set to Fast Startup, full LAN support is available in standby.
