Power on and power off a 5V LED with SSC-32 and Lynxterm

Hello all,

For the moment, I have only one question :

  • Can I power on and power off a 5V LED connected directly to the SSC-32 ?
    With Lynxterm and serial commands, off course.

In advance, many thanks for your reponse… and sorry for my bad english.

Sure, there is a command to drive the output pin to 0 or 1. You may have to connect the LED such that a 0 turns it ON as I am not certain the SSC-32 can source more than a few mA. If you connect the +Anode to +VS and the -Kathode to signal then when you set the port to 0 it will turn the LED on.

Edit: page 6 of ssc-32 user’s manual shows the discrete output command.

Many thanks for your answer, EddieB.

If I use many LED, it’s preferable to use another battery (external battery) to power only my LED ? Control one or more LED, it’s only a test for me because I want finally control cold cathode and maybe El Strip with my SSC-32…

If you are just swiching a logic level on/off input then no problem. An LED is not much current to operate. Be careful of how much current you need to run CCFL and EL drivers… If you are switching the actual power to run the driver it is possibly a problem.

If you’re looking to drive more than just a few milliamps, you’ll be wanting to use some sort of switching circuit between the SSC-32 and the lighting circuit.

There’s a thread] in the “General Electronics” section of the forum, where we’ve provided a number of examples of how to drive higher currents with logic-level inputs.
