7.1.6 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM
Function: Only the power for the low voltage lines (16 V, 12 V, and 6.5 V) is on, and the power for the high voltage lines (VSUS, VADR) is off.
A
Usage:
1. Use when only an operational check for the low voltage lines is required, such as when making repairs. 2. Use when rewriting of a program for each microcomputer is required.
Methods: 1 Set the slide switch (S5201) on the DIGITAL VIDEO Assy to its upper position (See Fig. below). 2. Send the "DRF" RS232C command to turn the large-signal system off. 3. Send the "DRN" RS232C command to turn the large-signal system on.
Notes: � As the unit enters Power-Down and Muting On mode when Methods 1 and 2 are performed, and power-downs other than those caused by the power (PS_PD) and DC-DC-converter (DIGITAL_DC-DC) circuits are not activated. � If the slide switch is set from OFF to ON while the power is on, a power-down will occur. Be sure to turn the power off before switching the slide switch. � When using the RS232C commands, as with the slide switch, do not use the "DRN" command (DRIVE ON) while the power is on, although doing so will not cause a power-down. � Although the "DRF" RS232C command is enabled during Standby, if the power is turned on then turned off, the unit will return to "DRN" mode.
