You can't. The DX-1G only has fiber optic connection options. Ike's have only Sync Cord connections. I would get the YS- 110 in case you want to switch to DSLR later like I did. My DX-1G is now my backup camera. Another option for you is Inon which has fiber optic connection AND sync cord connection like the YS-110. the 2000 model is almost the equivalent of the YS-110. the Z240 has more output but costs a bit more.
Either way, you will need to use manual mode. The only way you could get proper exposure is if you switched the camera to Auto mode. In manual, TTL will not work. It really surprised me too when I found out. TTL works when the flash output is controlled by the camera. On the 1G, the flash output CANNOT be controlled. On auto, the camera will compensate by adjusting other in camera modes but the flash output is ALWAYS the same. This means TTL via optical connection will just dump as much light as the onboard flash. No compensation.
This is not too big an issue anyway. You will learn pretty quick what setting to use each time for Macro and adjust as such......WA and CFWA (Close focus Wide angle) is a little more difficult. Practice and multiple shots help. Use RAW and even slightly underexposed shots can be recovered.
