*OPT? - Optional Identification Query
This command does an optional identification query, which means it displays the software version.
Example:
*OPT? Query of version number
08.06.2012 V42 Unit answers: Version 42 vom 08.06.2012
OVP[,<U
ovp
>] - Over Voltage Protection
This command adjusts the over voltage protection. Entering the command without parameter displays the present set
point. If the set point is higher than a maximum of 1.2 x voltage of the unit, the range error bit within the ESR register
of the interface is set. The present set point remains unchanged.
Example:
GTR
Remote operation mode
OVP,200 Over voltage protection 200 V
UA,100 Output voltage 100 V
IA,10 Output current 10 A
SB,R Output open
PCx[,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>,<timeout>] - Program Communication
This command adjusts the interfaces. The LAB/SMS/E has a maximum of 3 digital interfaces (x = 1, 2 or 3). The corre-
sponding commands are
PC1
,
PC2
or
PC3
. Type and number of parameters depend on the type of interface. Cur-
rently there are no settings available for GPIB and LAN. Entering the command without parameter displays present
interface parameters.
Parameter Function
<baud> Baud rate in bps
<parity>
Data parity
O = Odd = Uneven parity
E = Even = Even parity
N = None = No parity bit
<data bits> Number of data bits
<stop bits> Number of stop bits
<handshake>
Handshake
H = Hardware
S = Software
N = None (no handshake)
<echo>
Character echo
E = Echo = echo on
N = None = echo off
<timeout> Timeout in ms when switching between sending and receiving (RS485 only)
Allowed parameters for RS232 interface:
PCx,<baud>,<parity>,<data bits>,<stop bits>,<handshake>,<echo>
