The equipment template is a single line that is a base64 encoded bit stream as defined in rfc3548 using + and / as the 62nd and 63rd characters respectively. Numbers of varying number of bits are placed into the bitstream. Assuming that the bit stream already has 4 bits of data (the X's) adding a 5 bit number would have its bits placed like this: +-+-+-+-+-+-+ +-+-+-+-+-+-+ |1|0|X|X|X|X| | | | |4|3|2| +-+-+-+-+-+-+ +-+-+-+-+-+-+
