[ 3 ] Remote wakeup program
■ File name
The BHT may handle the file named "BHTRMT.PD3" as a remote wakeup program.
Upon receipt of data containing a “WAKE” character string, the BHT checks whether the
BHTRMT.PD3 file exists. If the file exists, the BHT will start the remote wakeup operation
described in [ 2 ].
■ Settings for remote wakeup
To use the remote wakeup function, make the following I/O port settings with the OUT or WAIT
statement or INP function beforehand (refer to Appendix D, "I/O Ports"):
(1) Activate the remote wakeup function
You may activate/deactivate the remote wakeup function as listed below. The default is 0
(Deactivate).
(2) Set the transmission speed to be applied for remote wakeup
Set the transmission speed to be applied when activating the remote wakeup as listed
below. The default is 1 (9600 bps).
(3) Set the timeout for ready-to-receive state
Set the timeout length during which the BHT will wait for a “WAKE” character string after
receiving any data via the CU and becoming ready to receive. The default is 3 (seconds).
(4) Set the BHT station ID to be used in the BHT response message
Set a 6-byte numeric string referring to the lower 6 digits of the BHT serial number as a
station ID which will be used in the response message to the host. To write and read the
setting, use the extended function SYSTEM.FN3 (Functions #3 and #4). For details, refer
to Chapter 16, "Extended Functions."
