Users Manual & Installation Guide

PV- 5127: Power supply module with UPS

b (STATUS bit 3): Battery present.

b=0: Battery not present (empty or disconnected)

b=1: Battery present

BAT_STATUS (port 252h, read only): nn0cctvv

This port contains the following read-only battery status information bits.

vv(BAT_STATUS bit 1-0): Battery voltage. See the section Battery monitor and charger. vv=00: Empty or low

vv=01: Medium

vv=10: Full

vv=11: Disconnected

t (BAT_STATUS bit 2): Battery temperature, according to the battery temperature sensor input. When using the PV-1075 NiMH battery module, the sensor should be disconnected, and this bit always reports battery too hot.

t=0: Battery temperature OK, charger enabled

t=1: Battery too hot, charger disabled

cc(BAT_STATUS bit 4-3): Charger status.

cc=00: Charger off. When using the PV-1075, the charger is always off.

cc=01: Reserved

cc=10: Charger on, trickle charging

cc=11: Charger on, fast charging

nn(BAT_STATUS bit 7-6): Battery type. With the current firmware, the only possible value is 01.

nn=00: Reserved

nn=01: Lead-Acid, or PV-1075 NiMH battery module

nn=10: Reserved

nn=11: Reserved

RS232_STATUS (port 253h, read only): uuuu0000

This port contains the following read-only status bits. They reflect the status of the pins in the RS232 connector, whether input from the CPU, or output by the PV-5127. All four signals are active high, i.e. 1=signal active, 0=signal inactive. Note that RTS (UPS_active) has no function, apart from being readable in this port.

RS232_STATUS bit 4: CD (Lobat). Output from the PV-5127.

RS232_STATUS bit 5: CTS (Mainsfail). Output from the PV-5127.

RS232_STATUS bit 6: RTS (UPS_active). Input into the PV-5127.

RS232_STATUS bit 7: DTR (Shutdown). Input into the PV-5127.

SHUTDOWN (port 254h, read/write):

This port holds the current state of the Softoff state machine. Please see the section ATX and Softoff state machines. Possible values are:
