Example of an RS-232C Program

V 20.5 <cr>: program 20.5V

A 1.25 <cr>: program 1.25A

V 30 A 2 SEC 20 <cr>: program 30V, 2A, for 20 seconds

OVP 35 <cr>: set 35V for the over voltage protection

SEC 60 <cr>: enter 60 seconds

OCP 0 <cr>: disable OCP (Open circuit protection)

OCP 1 <cr>: enable OCP

STORE 120 <cr>: store current V/A values in memory location 120.

RECALL 100 <cr>: recall V and A values stored in memory location 100.

RECALL 110 <cr>: recall V and A values stored in memory location 110.

Step <cr>: enable ATS function. Starting step is 100 (recalled first in the

previous statement) and the ending step is 110 (recalled after

step 100).

? <cr> (Inquire all data)

V? <cr> (obtain the voltage value)

V 40.000 40.000 CV

A? <cr> (obtain the value of current)

A 01.000 00.999 CV

Note: The first set of data following the character V or A is the programmed value, while the

second set of data is the read back A/D value. The third set of data is the status (CV, CC) of

the unit. If the third set of data shows 0V, the unit is placed in the STBY mode. The unit

sends out a <new line> and <carriage return> after each line of data.
