DRF-SW-B
(TEST PIN)
Function:
It is an operational mode where the digital signal processing performs circuit operation but the power is not supplied to the
panel driving system (Vsus, VAddress) in order to avoid a power down (PD).
Application:
1. When it is necessary to check whether the signal output is correctly reaching the drive system in a repairing activity etc.
2. In the case of a PD, to determine whether the problem is with the panel drive-power supply or with the other system power
supply.
Method:
1. Short-circuit between the specified location of the POWER SUPPLY Unit and GND (Multi base section recommended),
using a jumper with alligator clips (refer to the photos below).
2. Execute [DRV S00] by RS-232C command. ([DRV S01] for release)
Supplemental explanation:
• When the panel drive-power is in OFF state, there will be no PD, except PS_PD, as the PD signal has been muted.
• If the clip is removed in the OFF state of the panel drive-power, PD will take place at the instance of clip removal.
Therefore, be sure to remove the clip after turning the power OFF.
• Under RS-232C command control, [DRV S01] (release) is possible during power ON. However, there is a possibility of
damaging the set. Therefore, make this operation only after turning the power OFF.
• Command [DRV S00/S01] is effective even during standby.
• When the main power switch is set to OFF, no command is accepted.
• When the AC power cord is unplugged, the panel drive-power OFF state established by the [DRV S00] command is
canceled. (The panel drive-power OFF state remains in effect even if the main power switch is set to OFF after that
command is sent.)
