Specifications are subject to change without notice
power off command via RS-232 ports of both THB-350 and RHB-350 with a set delay time (1 to 60
minutes) after the last input signal disappears; and will send a display power on command as soon as
the first input signal detected, and will automatically select that input. The switcher uses one RS-232
port to connect both external host (optional; only required for setup) and display in parallel with the
display in “listening” mode only (only display’s Rx pin connected). Here’s the wiring diagram:

Use the “2{xxx}R” and “1{yyy}R” commands listed in next page to setup the display power on and off
commands respectively, then use the “1*zR” command to enable the display power control feature
while setting the power off delay time at “z” minutes. Use “0R” command to disable the display power
control feature. Once setup finished, the external host is not needed for daily operations. The system
reset command “r” will not erase the stored display power on and off commands, but will disable the
display power control feature (factory default).
