Before using RS232/485 to control COTEK programmable SMPS (excl. AK Series),
make sure to read the following notes:
1. Make sure the voltage and current setting has been correctly delivered to EUT before setting the
command (Power <type>) to turn on / off the power supply. If OVP, or OLP LED signal has been
activated due to incorrect operation, enter command POWER <type> will allow you to operate the
EUT and setting command.
2. Every RS232/485 command character must be entered within 400ms, the ending point is judged by
CR LF (0D0A), program will disregard the command if the command entering time exceeds 400ms
per character.
3. After shut-down of the power of EUT, command setting will return to default, local mode.
4. After power on the EUT with command execution complete, EUT will switch to remote mode with
orange LED signal status. For detail LED signal info, please refer to the EUT datasheet.
5. Please refer to the CT-xxx user manual (Page 02) for the cable spec. connect in between the CT-xxx
controller board and EUT. Make sure to connect the cable as instructed on the user manual to avoid
CT-xxx damage.
6. CT-xxx boards could support max. 8 units parallel control function (ADDS0-7). Before controlling the
EUT, make sure the address is not in conflict with each other.
7. When controlling multiple EUT’s, make sure to query the Address (ADDS x) first before entering
command to avoid EUT retrieving the incorrect value. If only single EUT, there is no need to query
ADDS before entering command.
