Tendzone TYCHO T 1212/CA - Manual (Page 19)

When Scene 4 of the matrix is loaded, PIN-11 (i.e. RO 8) outputs low level, there is current running through the relay, and
the relay is switched; and when the matrix is switched to other scenes (such as Scene 3), PIN-11 (i.e. RO 8) outputs no
level, there is no current running through the relay, and the relay is not switched.
The actions are opposite if “output high, no output low” is selected.
If RO 8 has other biding parameters, such as level display, channel mute display, system mute display, etc., the working
conditions of the relay will be switched according to the changes of the matrix parameters.
1.2 Wiring Method of Output RO 1~4
Notes: outputs of RO 1~4 are ordinary 5 V outputs. Working modes of RO 1~4 and those of RO 5~8 are consistent, but the
output high voltage of RO 1~4 is 5 V. The maximum output current is 0.4 mA when it outputs the high level and -30 mA
when outputs at low level.
Example 1: Direct Electrical Output
Settings of RO 1 on the PC interface are as follows:
