TDK 750W HALF RACK Rear Panel RS232/RS485 Connector, 6 RS232/RS485 port in Local mode

Page 59

2. There are two Remote modes:

1. Remote:

In this mode, return to local can be made by the front panel REM/LOC or

 

via serial port command RMT 0. Set the unit into Remote mode via serial

 

port RMT 1 command.

2.Local Lockout: In this mode the unit can be returned to Remote mode via the serial port RMT 1 command or by turning off the AC power until the display turns off, and then turn it to on again. In local Lockout mode, the front panel REM/LOC button is not active. Set the unit into Local Lockout mode via se- rial port RMT 2 command.

7.2.6RS232/RS485 port in Local mode

When the power supply is in Local mode, it can receive queries or commands. If a query is re- ceived, the power supply will reply and remain in Local mode. If a command that affects the out- put is received, the power supply will perform the command and change to Remote mode.

Serial commands may be sent to set the status registers and read them while the unit is in Local mode. If the Enable registers are set (refer to Section 7.11) the power supply will transmit SRQ’s while in Local.

7.2.7Front panel in Remote mode

Front panel control in Remote mode is Disabled except for:

1.PREV: use to preview the Voltage and Current setting.

2.OVP/UVL: use to preview the OVP/UVL setting.

3.LOC/REM: use to set the unit into Local mode.

In Local Lockout mode, only the PREV and OVP/UVL pushbuttons are active.

7.3 REAR PANEL RS232/RS485 CONNECTOR

The RS232/RS485 interface is accessible through the rear panel RS232/RS485 IN and RS485 OUT connectors. The connectors are 8 contact RJ-45. The IN and OUT connectors are used to connect power supplies in a RS232 or RS485 chain to a controller. Refer to Fig. 7-1 for IN/OUT connectors.
