    H31.0.31.6C-06 User’s Manual GMH3150 page 9 5 The Serial Interface By means of the serial interface and a suitable electrically isolated interface adapter (GRS3100, GRS3105 or USB3100) the device can be connected to a computer for data transfer. With the GRS3105 up to 5 devices of the GMH3xxx- series can be connected to one interface (see also manual of GRS3100, GRS3105 or USB3100) To avoid transmission errors, there are several security checks implemented e.g.
