    Operation The C52/C53 supports four kinds of operations. They are: • Point-to-point, 4-wire full duplex • Point-to-point, 2-wire half duplex • Multidrop, 4-wire full duplex • Multidrop, 2-wire half duplex Note: If possible, connect the GND of both sides together to gain better signals. For example, you may need one more GND connection in addition to the 4-wire or 2-wire connections.
