443B101/443B102 40
Manual 19854 Rev. D
ECN 50523
Command: WRAR
Purpose: Writes 8 bytes to the application register scratchpad of the TEDS chip (DS2430).
Response: The module responds with a “0” to tell the calling process the command has
been received.
Command String: XYC0ZWRAR
Description: X—Rack number of the target module (Range: ASCII printable characters, 0
through 3)
Y— Slot number of the target module. (Range: ASCII printable characters, 0
through 7)
C0Z— Module type for the target. Specifying "C01" in this argument addresses
a 443B101, specifying “C02” addresses a 443B102.
WRAR— tells the module to write 8 bytes to the application register of a TEDS
device.
Response String: “0”
Example: Command String: “06C02WRARAABBCCDDEEFFAABB”
Response String: “0”
The 443B102 in rack 0 and slot 6 is commanded to write 8 bytes of hex data
(“06C02WRARAABBCCDDEEFFAABB”) to the application register of a TEDS
device.
Note:
1) If the application register is locked, this command will have no effect on its
contents. See STAT command description for information regarding how to
determine the status of the application register.
2) After receiving the RDAR or WRAR command, the 443B will be left in TEDS
mode and will not be able to power an ICP
®
sensor. This is because the
application register memory is non-volatile when not locked so that whatever
was written would be lost if the unit was returned to "analog" mode. This
feature allows the host to check the data in the application register before
locking it. The 'TOFF' command must be issued to return the unit to analog
mode.
