4.4 Digital Input / Output
As of firmware v2.27, the digital input functions as the ‘Global Forced Off’ signal. This is a
normally-closed, volt-free signal.
Upon detecting an ‘Open’ input, all available fancoils will be switched off and their remote-
controllers will be inhibited. These settings are refreshed every 10 seconds while the input
is ‘Open’.
When the input is subsequently ‘Closed’, the remote-controller inhibits are removed, but
the fancoils remain off.
The digital output currently has no functionality.
4.5USB
The USB interface is used for configuration via a PC and for upgrading the firmware.
Ensure that the correct USB driver has been installed prior to
connecting the Black Pear to a PC.
4.6 Ethernet
The Black Pear is a 10/100Base-T half/full duplex device. It supports auto-negotiation and
also features auto-crossover (Auto-MDIX), allowing the use of either a straight-through or
crossover cable.
It does not currently support DHCP and will therefore require the IP address, gateway
address and subnet-mask configuring to match the host network it is attached to.
If the unit is only being accessed via the local network then set the gateway address to be
the same as the IP address, otherwise enter the address of the appropriate gateway or
router.
