23. Use assist cable for bulb ramp / bulb HDR

Default: Yes

By default Promote Control will expect an optional Bulb Ramp / Bulb HDR Assist cable connected in Bulb Ramping / Bulb HDR mode. If your camera is incompatible with Bulb Ramping assist cable, change this setting to No. Please note that without a Bulb Assist cable, Promote Control will be unable to achieve as fast a shutter speed in Bulb mode as with that cable connected and enabled via this setting.
