Register 11:9 = Setpoint ID Register 8 = Access Level needed to modify Register 7:6 = Value Register 5:4 = Minimum Register 3:2 = Maximum Register 1:0 = Resolution

Setpoint Write $03F9 (1017) - 5 registers (10 bytes) long - Write

Writes a specific Setpoint ID and value to change a setpoint. (Register numbers listed below are offsets from the starting register number of this parameter, given above.)

Register 4:2 = Setpoint ID Register 1:0 = New Value

Setpoint Data Value $03FE (1022) - 2 registers (4 bytes) long - Read

Reads the value of the setpoint specified by the Setpoint ID for Read Modbus register.

Miscellaneous

Battery Voltage $00CA (202) - 1 register (2 bytes) long - Read

Measured electrical potential of the battery voltage at the control. The EMCP 3 can report the voltage of the supply that is powering it over the data link by means of the Battery Voltage parameter. This is usually the cranking battery or batteries. Note that the voltage is read at the EMCP, not at the battery terminals. For high power draw cases, this voltage may be noticeably lower than the voltage at the battery terminals.

Resolution Offset Data Range

0.05 V / bit 0 V 0 to 3212.75 V

Lamp Test Command $012F (303) - 1 register (2 bytes) long - Write

Commands the control to conduct a lamp/display test of the EMCP 3 control panel. Writing TRUE turns on all of the LEDs, but does not darken the LCD display on the control panel, as the Lamp Test button on the control panel does. To end the lamp test, a FALSE must be written to this register.

Resolution Offset Data Range

1 / bit 0 0 to 1

Bit Definitions: 00 = FALSE 01 = TRUE
