Installation and Operating Instructions
TERMINATING/BIASING THE BAXNET NETWORK
The keyboard has built in network termination and/or biasing. For most small to medium sized installations, it should not
be necessary to change the switches from their default settings. Only for large installations should your network require
biasing and/or terminating. Contact Baxall Security Limited for advice. The switches are shown below for your reference.
The default setting for switches 1, 2 and 3 is OFF. Switch 4 is not used.
BAXNET - UNIT IDs AND KEYBOARD PRIORITIES
The Unit ID is a number between 1 and 32. It is used to select a ZMX.. or ZTX6/.. for control from your keyboard and also
to decide the priority of one keyboard over another (lower numbers take precedence).
UNIT IDs - KEYBOARD PRIORITIES
The priority of keyboards over each other is determined by the value of the Unit ID. Keyboards with a lower value Unit ID
take precedence over keyboards with a higher Unit ID. A higher priority keyboard can take control of a ZMX.. or ZTX6/..
immediately and at any time from a lower priority keyboard. A lower priority keyboard must wait for 30 seconds from the
last command by the higher priority unit before it can take control. If another command from the higher priority keyboard
is sent in this time then it must wait another 30 seconds. The following control messages are displayed on on the ZKX
keyboard:
CONTROL LOST
Indicated when a higher priority keyboard on BaxNet has taken control or when the current keyboard
has timed out.
CONTROL UNIT #n Indicated when the current keyboard has control over all other keyboards on the BaxNet connection.
To re-activate control of a keyboard that has timed-out (CONTROL LOST), operate the pan or tilt keys.
