Table 4-6.Host Port Commands for RS-232 with AE Bus (Continued)

Command		Number of	Number of
	Description	Host Data	Response
		Bytes	Data Bytes
8	Specifies the output setpoint level for	2 data bytes	1
setpoint	whatever method of output regulation has	16-bit value
	been selected. Accepts a value of 0 to 8000
	W (for the 8 kW option) or 0 to 10000 W (for
	the 10 kW option) when forward or load
	power regulation is selected. Regular units
	report in units of watts. HALO units report in
	units of tenths of watts.
9	Specifies the external feedback value that	3 data bytes
max ext	corresponds to 10 V on the User port;	16-bit value
feedback	requires data bytes arranged as follows:	8-bit value
	• First/second byte = a 16-bit value in the
	range of 500 to 5000.
	• Third byte = the number of decimal
	places (0 to 4) used to display the
	external feedback signal on the operator
	panel.
11	Specifies which target is active; accepts a	1 data byte	1
select	value of 1 to 4. (Readback command is 156.)	8-bit value
active
target
12	Sets the life (in kWh) of the target you	5 data bytes	1
set target	specify. Requires five data bytes arranged as	8-bit value
life	follows:	32-bit value
	• First byte = the target number
	• Second, third, fourth, fifth bytes = target
	life in kWh
	Note: A decimal is implied—to get 1 kWh,
	send a value of 100.
	(Readback command is 157.)
14	Sets the active control mode of the generator;	1 data byte	1
control	possible choices are: 2 = host, 4 = User port	8-bit value
transfer	(analog).
15	Specifies how long the generator can produce	2 data bytes	1
out-of-	output that is not equal to the programmed	16-bit value
setpoint	setpoint level. Accepts a value of 0 to 599 s.
timer	(Readback command is 184.)
