245
RS-232C
D-SUB 9-pin connector (conforms to EIA-232-D)
Sets panel functions except the power switch and reads measured
values
Supports the SCPI and IEEE std. 488.2-1992 command set
Baud rate: 2400, 4800, 9600, 19200, 38400 bps
Data length: 8-bit, Stop bit: 1, 2-bit, Parity bit: None, Odd, Even.
USB
Conforms to USB 2.0 Specifications and USB-CDC ACM
Sets panel functions except the power switch and reads measured
values
Communication speed 12 Mbps (Full speed)
Analog External Control
Load on/off Control Input
Turn on the load with low (or high) TTL level signal
Load on Status Output
On when the load is on (open collector output by a photocoupler)
Range Switch Input
Switch ranges L, M, and H using a 2-bit signal
Range Status Output
Outputs range L, M, or H using 2-bit signal (open collector output
by a photocoupler)
Trigger Input
Clear the sequence operation pause with a high TTL level signal
for 10 μs or more.
Alarm Input
Activate alarm with low TTL level signal input
Alarm Status Output
On when OVP, OCP, OPP, OTP, UVP, RVP, or when an external
alarm input is applied (open collector output by a photocoupler)
Short Signal Output
Relay contact output (30 VDC/1 A)
External Voltage Control
Operates in CC, CR, CV, CP, or Cx+CV mode
0 V to 10 V correspond to 0 % to 100 % of the rated current (CC
mode), rated voltage (CV, Cx+CV mode), or rated power (CP
mode).
0 V to 10 V correspond to maximum resistance to minimum
resistance (CR mode)
External Resistance Control
Operates in CC, CR, CP, or CV mode
0 Ω to 10 kΩ correspond to 0 % to 100 % or 100 % to 0 % of the
rated current (CC mode), rated voltage (CV mode), or rated power
