Did your JJC TM-PK1 come with instructions? I tried to find the manual online, but came up empty. On most similar devices you have the ability to set delay, duration, interval, and count. For a single 2' exposure the setting would be:
TM-PK1- Self - 00:00:00 (starts now)
- Bulb - 00:02:00 (holds shutter button for 2')
- INTV - 00:00:00 (none, we are only doing this once)
- No - 1
KP Camera- Mode : "B" (untimed)
- AF : OFF
- Slow Shutter Speed NR : OFF*
I hope this is applicable and helps.

* If the slow speed NR is left on, the camera will be unresponsive for at least 2' additional after the exposure is finished to allow for creation of a dark frame to be subtracted from the image.
