PHOTTIX Odin 1.5 TTL Trigger for Canon Firmware 2.03 for MAC

Fixes:
- Improved compatibility with EOS M cameras.
- Test Button and Light Meters: Pressing the Test button on the transmitter will cause the flashes in A, B and C groups to fire simultaneously. Group(s) turned off will not fire. When the flashes in A, B and C groups are set to Manual (M) mode, pressing the Test button on the transmitter will cause the flashes to fire an initial low-power pre-flash. The flashes will fire simultaneously at their set manual power levels 2.5s later. This feature allows for light meters to be used correctly.
- Second Curtain Sync: The Second Curtain Sync (SCS) function will work correctly with all cameras (except 1Dx) supporting “radio wireless system” in the camera flash menu. To use SCS the “radio wireless system” in the camera flash menu must be set to “OFF.”
- 1Dx Mode: A menu has been added to turn 1Dx compatibility on and off. Press and hold the “+” and “HS” buttons to access the 1Dx function menu. Pressing and holding the “+” and “HS” buttons (with TCU turned on) for approximately 2 seconds will access to the “1d-” function menu. If using a 1Dx, set to “ON” for best compatibility. For other camera models, use the default setting of “OFF”.
- Improve Odin 1 compatibility: Odin 1.5 (v2.03) is completely compatible with the Odin 1 (v1.24).
