Communication protocol
TF series power supplies support digital communication interface with a Host PC based on RS 232 communication
protocol. The UART control interface RXD and TXD are TTL signals. These signals must be transformed to communicate
with host PC by CT-2XX Communication Board. This can be acquired from SL Power Electronics. Then, the functions below
can be operated:
1. ON / OFF control and ON / OFF Status Query.
2. Output voltage / current limit setting and Query.
3. Actual output voltage, output current and internal temperature Query.
4. Status of the unit Query.
5. Manufacturing related data Query (Include model name, serial number, MFG date etc ...).
1. Host PC
2. CT-XXX communication board with 24-wire cable mating to C2 connector on TF power supply
3. USB to RS 232 adapter (with cable)
4. TF series power supply
5. Load (recommended, optional)
1. Run setup.exe le from SL-TF Installer and follow the recommended steps in SW installer tool.(Hint: The SW installer
adds NI LabVIEW run-time 2011 and SL-TF_Demo Project to the system.)
2. If USB to RS232 adapter is used for rst time, install drivers according to instructions provided with the hardware.
(Hint: most likely Windows OS will recognize and install default USB drivers which are suitable for required use.)`
Follow the steps listed below to connect CT-XXX communication board to TF series power supply:
1. remove supplied jumper from C2 connector
2. connect rst end of 24-wire cable to C2 connector on TF power supply
3. connect second end of 24-wire cable to CN1 port on CT-XXX communication board
4. connect USB to RS 232 Adapter to host PC.
5. connect USB to RS 232 to CT-XXX communication board (9 pin RS 232)
6. Make sure the address potentiometer is selected correctly. This is important for parallel operation of PS where two
PS are not allowed to have same address.
7. Connect AC power cord to TF power supply
8. Connect load to TF power supply (recommended, optional)
