CHAPTER 7 RS232 & RS485 REMOTE CONTROL

7.1 INTRODUCTION

This Chapter describes the operation of the GenesysTM 3300W power supplies via the serial commu- nication port. Details of the initial set-up, operation via RS232 or RS485, the command set and the communication protocol are described in this Chapter.

7.2 CONFIGURATION

7.2.1 Default setting

The power supply is shipped with the following settings:

-Address	6	-Output	Off
-Baud-rate	9600	-Start up mode	Safe-start
-RS232/485	RS232	-OVP	Maximum
-Vout setting	0	-UVL	0
-Iout setting	Maximum	-Foldback	Off
-Master/Slave	H1 (Master)	-Front panel:	Unlocked (UFP)

7.2.2Address setting

The power supply address can be set to any address between 0 and 30. Follow the instructions de- scribed below to set the unit address.

1.If the unit is in Remote mode (front panel REM/LOC LED illuminated), press the REM/LOC button to put the unit into Local mode.

2.Press and hold for the REM/LOC button for approximately 3 sec. The VOLTAGE display will indi- cate the unit address.

3.Using the VOLTAGE adjust encoder, select the unit address.

To preview the power supply address at any time, press and hold the REM/LOC button for approx. 3 sec. The VOLTAGE display will indicate the power supply address.

7.2.3RS232 or RS485 selection

To select between RS232 or RS485 set the rear panel setup switch SW1-6 position to: -DOWN for RS232

-UP for RS485

7.2.4Baud Rate setting

Five optional Baud rates are possible: 1200, 2400, 4800, 9600 and 19200. To select the desired rate, the following steps should be taken:

1.If the unit is in Remote mode (front panel REM/LOC LED illuminates), press REM/LOC button to put the unit into Local mode.

2.Press and hold the REM/LOC button for approximately 3 sec. The CURRENT display will show the unit Baud Rate.

3.Using the CURRENT adjust encoder, select the desired Baud Rate.

7.2.5Setting the unit into Remote or Local mode

1.The unit will be put into Remote mode only via serial communication command. Commands that will put the unit into Remote mode are:

RST	PV n
OUT n	PC n
RMT n

(for n values see Tables 7-4, 7-5 and 7-6)
