Routing TTL pulses out of the STP100C BNC connector
2 x JUMP100
The STP100C receives a digital pulse coming from a stimulus presentation program, either through the 37 pin connector or the 25 pin connector.
To route a digital pulse from a presentation program, for example to drive another device outside of the MP system, take a JUMP100 and insert into the Digital I/O port on the back of the UIM100C (note, the UIM100C is separated and the port strip has a screw to secure the JUMP100C).
Route the other end of the jumper cable into digital channels 0 – 3 on the UIM100C, this corresponds to the Coaxial outputs on the front of the STP100C 1-4 respectively.
Next route a JUMP100 from GRND D on the UIM100C to channel 4 digital I/O on the UIM100C. This completes the circuit and activates the front relays.
In the software, go to MP150>SHOW MANUAL CONTROL.
In the MANUAL CONTROL dialog box, set the DIGITAL I/O for Channels 0 -7 to INPUT. Set the DIGITAL I/O for channels 8 – 15 to read INPUT as well.
As an example, you have a digital TTL pulse coming into the back of the STP100C for channel 8. This channel will be enabled in AcqKnowledge and every time a pulse comes through to that channel, it will route to channel 0. A pulse will be seen coming out of BNC output #1 on the STP100C.
