PROTOCOL SERIAL COMMANDS
‘wg’ Command — Write Setpoint State
This command is sent by the master to set the setpoint state of an STXplus. This can only be
accomplished if setpoint test is enabled (see command “GB/PB“). Acceptable values for setpoint
number is 1 and 2. The range of acceptable values is 0-1 where 0 is setpoint off or 1 is setpoint
on. For this example, the master sets setpoint 1’s state for an STXplus at address 01 to 1
(setpoint on). Any of the 6 leading zeros may be omitted.

‘GB’ Command — Read Setpoint Test Mode
This command is sent by the master to request the STXplus to send the setpoint test mode.
Acceptable values for setpoint number is 1 and 2. The range of acceptable values is 0-1 where
0 is test mode disabled or 1 is test mode enabled. The default value is 1 (test mode enabled).
For this example, the master requests setpoint 2’s test mode for an STXplus at address 01 which
returns 0 (test mode disabled) and a checksum of 50.

Acceptable values for setpoint number is 1 and 2. The range of this value can be ±2,147,483,647.
The default value is 0. For this example, the master requests setpoint 1’s value for an STXplus at
address 01 assuming it is using a format of 4(X.XX), which returns 347.51 engineering units and
a checksum of 32.
