*
The charging operation can be determined by the setup over D0, position 4 on the DIP switch. When D0 is “ON”, RCB-1600 follows a built charging curve
to charge the batteries; when D0 is “OFF”, the charging operation is completely defined by the control over PMBus, PV/PC or SVR. Please refer to Table 3-7
(right).

Each RCB 1600 unit should have their unique and own device address to communicate over the PMbus 7 bit address setting pins are used
-
. -
to assign a device address for a RCB 1600 unit as shown in the below description
-
,
.
A0-A2 allow users to designate the address for each RCB-1600 unit; these three bits are defined through a 4-pole DIP switch on the rear
panel of the rack shelf. There are up to 8 different addresses are available to be assigned. Please refer to Table 3-7(left) for the detailed
setup advice.
When it is opted for charging curve, D0 set to ON, charging curve function is enabled with additional PMBus commands.
There are 4 built-in charging curves, “default” curve, one pre-defined curve for “gel battery”, one pre-defined curve for
“flooded battery” and one pre-defined curve for “AGM battery”. Each curve can be selected by Command B4h
CURVE_CONFIG. Please refer to Table 3-8.
In addition users are able to customize their own charge curves which will be

,
stored to “default” after modification Vboost can be set by Command B1h CURVE VBST VFloat can be set by Command

Charge current level of stage1 can be set by Command B0h CURVE ICHG Taper current level

NOTE: 1.The updated charging parameters is saved into EEPROM. The updated charging curve takes effect after RCB-1600 is restarted.
2.When charging curve is enabled, the following commands will be invalid while other PMBus commands are effective: Command 01h
OPERATION (regarding Remote ON-OFF function), Command 22h VOUT_TRIM (regarding Output voltage programming function) and
Command 46h IOUT_OC_FAULT_LIMIT (regarding Output current programming function).
