5.1.1 Syntax
The commands are transmitted in ASCII. All commands are terminated by the sequence <CR> <LF>
(0x0D 0x0A , 13 10 respectively). Leading zeros can be omitted on input, output is in fixed format.

Read module identifier
# *
# * nnnnnn ; n.nn ; U ; I *
(unit number ; software rel. ; V
nom
; I
nom
)
Read break time W * W * nnn * (break time 2 ... 255 ms)
Write break time W=nnn * W=nnn * * (break time = 2 - 255 ms)
Read actual voltage channel 1 U1 * U1 * { polarity / mantisse / exp. with sign } * (in V)
Read actual current channel 1 I1 * I1 * { mantisse / exp. with sign } * (in A)
Read voltage limit channel 1 M1 * M1 * nnn * (in % of V
nom
)
Read current limit channel 1 N1 * N1 * nnn * (in % of I
nom
)
Read set voltage channel 1 D1 * D1 * { mantisse / exp. with sign } * (in V)
Write set voltage channel 1 D1=nnnn.nn * D1=nnnn.nn * * (voltage corresponding resolution in V; <M1)
Read ramp speed channel 1 V1 * V1 * nnn * (2 ... 255 V/s)
Write ramp speed channel 1 V1=nnn * V1=nnn * * (ramp speed = 2 - 255 V/s)
Start voltage change channel 1 G1 *
G1 * S1=xxx * (S1 , ⇒ Status information)
Write current trip L1=nnnnn * L1=nnnnn * * (trip corresponding resolution range mA > 0)
Cannel 1 Range “mA” LB1=nnnnn * LB1=nnnnn * * (trip corresponding resolution range mA > 0)
Range “µA” LS1=nnnnn * LS1=nnnnn * * (trip corresponding resolution range µA > 0)
Read current trip L1 *
L1=nnnnn * * (see above, for nnnnn=0 ⇒ no current trip)
Cannel 1 Range “mA” LB1 *
LB1=nnnnn * * (see above, for nnnnn=0 ⇒ no current trip)
Range “µA” LS1 *
LS1=nnnnn * * (see above, for nnnnn=0 ⇒ no current trip)
Read current trip channel 1 L1 * L1 * { mantisse / exp. with sign } * (s.a., current trip in A)
Read status word channel 1 S1 *
S1 * xxx * (S1 , ⇒ Status information)
Read module status channel 1 T1 *
T1 * nnn * (code 0...255, ⇒ Module status)
Write auto start channel 1 A1=nn *
A1=nn * * (conditions ⇒ Auto start)
Read auto start channel 1 A1 *
A1 * nnn * (8 ⇒ auto start is active; 0 ⇒ inactive)
* = <CR><LF>
The second channel of the supply is addressed by replacing 1 with 2 !
Status information: ON Output voltage according to set voltage
