Manual WM-IIRO-8
Example:
Assuming that the last comm and was "I", ask pod to resend last response
SEND: n
RECEIVE: FF[CR];or whatever the data was
Note: This command may not be used for the FASTDATA command, as they exceed the 255
character limit. Use the "D" comm and to perform the same task for these three commands.
Hello Message
H* Hello message
Any string of characters starting with "H " will be interpreted as this command. ("H[CR]" along is also
acceptable.) The return from this command takes the form (without the quotes):
"=Pod aa, W M-IIRO-8 Rev 1.01 Firmware Ver:x.xx ACCES I/O Products, Inc."
aa is the pod address
rr is the hardware revision, such as "B2"
x.xx is the software revision, such as "1.01"
Example:
Read the greeting message
SEND: Hello?
RECEIVE: =Pod 00, WM-IIRO-8 Rev B2 Firmware Ver:1.01 ACCES I/O Products,
Inc.[cr]
Programming Pod Address
A=xx Program the currently selected pod to respond at address xx
This com mand changes the pod's address to xx. If the new address is 00, the pod will be placed into
non-addressed mode. If the new address is not 00, the pod will not respond to further
communications until a valid address com mand is issued. Hex numbers 00-FF are considered 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 EEPROM and will be used even after power-down until the next
"A=xx" command is issued. Note that, it the new address 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.
Example:
Set the pod address to 01
SEND: A=01
RECEIVE: =:Pod#01[CR]
Set the pod address to F3
SEND: A=F3
RECEIVE: =:Pod#F3[CR]
Take the pod out of addressed mode
SEND: A=00
RECEIVE: =:Pod#00[CR]
