GPS connection

GPS channels are sourced from the GPS connector on the EXRCPU layer. EGPS-200, EGPS-200-Plus and Garmin GPS modules are supported. See GPS channels and www.hbm.com for more information.

The Garmin GPS (model GPS18X-5Hz) module requires the 5 Vdc power option and draws about 0.5 W. EGPS-200 and EGPS-200-Plus modules require the 12 Vdc power option and draw about 2.4 W. On boot up of the SomatXR/eDAQXR data processor, the power is always set to 5 Vdc.

With the power option set to 5 Vdc, the EGPS-200 and EGPS-200-Plus modules operate in a minimal mode that is sufficient to send a message to the processor allowing it to identify the module. When the processor receives this message, it switches to the 12 Vdc power mode.

CAUTION
The Garmin module will be instantly destroyed if it is connected to the GPS connector with the 12 Vdc power option selected! As such, always power off the EXRCPU before connecting a Garmin GPS if an EGPS-200 or EGPS-200-Plus module was previously connected.
