Notes & Observations
The five-pin LEMO power supply I have did not fit the GRX1200. However the pin sockets of the GRX1200's DC in connector are just slightly larger than 0.1“, Dupont-style header pins will slightly fit. Adding a ~10º bend to the pins provides enough deflection and springiness to hold the pin in place. The top-center pin is +V, and the #3 pin, working around right to left, is ground. The ground pin is common to the ground on the RF connector, so it's easy to verify.
