bicker_ser -a UPS_NAME [OPTIONS]

bicker_ser supports all Bicker UPSes shipped with the PSZ-1053 extension module such as UPSIC-1205, UPSIC-2403, DC2412-UPS and DC2412-UPS-LD.

The needed cable is a standard pin-to-pin serial cable with pins 2, 3 and 5 (on DB9 connector) connected.

This driver supports no extra arguments from ups.conf(5).

Depending on the type of your UPS unit, some of the following variables may be changed with upsrw(8). If the driver can’t read a variable from the UPS, it will not be made available. Whenever not explicitly stated, any variable can be disabled, in which case the action it performs will not be executed. To disable a variable, set it to an empty value.

ups.delay.shutdown (in seconds, default disabled)

If activated and the UPS is in battery mode and the set time has expired, the output will be disabled, and the UPS and energy storage will be disconnected.

ups.delay.start (in seconds, default disabled)

If activated and a restart condition switches the UPS output off and on again, the set time is the delay between switching on and off. The time should cause a defined off time so that capacities in the application can be discharged.

battery.charge.restart (in percent, default disabled)

If activated and the UPS is off or restarts, the UPS output will not be released until the energy storage device has the set charge state. The energy storage device is charged in the meantime.

battery.charge.low (in percent, default 20)

If activated and the UPS is in battery mode and the battery level drops below the set value, a shutdown command via relay event is signaled.

experimental.output.current.low (in mA, default 200)

If activated and the UPS is in battery mode and the current drops below the set value, the output of the UPS will shut down and disconnect the energy storage to prevent self-discharge.

experimental.ups.delay.shutdown.signal (in seconds, default disabled)

If activated and the UPS is in battery mode and the set time has elapsed, a shutdown command via relay event is signaled.

experimental.ups.delay.shutdown.signal.masked (in seconds, default disabled)

If activated and the UPS is in battery mode and the signal at the IN-1 input is high and the set time has expired, a shutdown command via relay event is signaled.

experimental.battery.charge.low.empty (in percent, default 20)

This parameter stores the threshold value for the "Battery Empty" signal. Currently this setting is only valid for relay signaling. Cannot be disabled.

experimental.ups.relay.mode (default 0x01)

This parameter controls the behavior of the relay in case of different events. Cannot be disabled.

Available relay modes:

0x01	On power fail (normally closed)
0x02	On power fail (normally opened)
0x03	Shutdown impulse (1 second)
0x04	Battery low signal (normally closed)
0x05	Battery defect signal (normally closed)

shutdown.return

Turn off the load and return when power is back.

ups.delay.shutdown is not honored
