Programming Pod Address
A=xx
Program the currently selected pod to respond at address xx
This com m and cha nge s the pod 's addres s to xx. If the new a ddre ss is 00, the pod will be plac ed into
non-add ressed mod e. If the new address is not 00, the pod will not respond to further
comm unications until a valid address com m and is issued. Hex num bers 00-FF a re cons idered valid
addresses. The RS485 specification allows only 32 drops on the line, so many addresses will be
unused.
The new pod address is saved in EEPRO M and will be used even after power-down until the next
"A=xx" com m an d is issue d. N ote tha t, it the new addres s is not 00 (i.e., the pod is configured to be
in addressed mode), it is necessary to issue an address command to the pod at the new address
before it will respond.
The pod returns a message containing the pod number as confirmation.
