5.0 Wire, ground, and power
Use a copper wire of sufficient size to ensure the voltage across the transmitter
power terminals does not drop below 9 Vdc. Power supply voltage can be
variable, especially under abnormal conditions such as when operating on battery
backup. A minimum of 12 Vdc under normal operating conditions is
recommended. Shielded twisted pair Type A cable is recommended.
