The System ID is the address of the master control unit on the network.
Net Faults is a counter keeping track of the number of times there is a network failure or a control
unit goes off-line. If power is removed from a control unit, it will go off-line and the counter will be
incremented. A high number in this field may indicate a loose wire somewhere in the
communication network.
P/O Self Test Fail is a counter keeping track of the number of times there has been a power-on
RAM check failure. This number should be 0. A high number in this field indicates the control
unit’s RAM is being corrupted. This may be due to electrical events such as sparks or static
charges, or it may be due to magnetic interference.
P/O Count is a counter keeping track of the number of times the system’s power has been cycled
on. A high number in this field indicates the control unit’s power is being cycled off and on. Verify
the control unit’s power connections are secure and that its power source is operating properly.
Net Security identifies if all doors on the network are secured or unsecured per the global secure
command (see the Global Secure command on page 38).
Status of Doors identifies how many and which doors are secured. An eight digit hexadecimal
value is displayed in the status of doors field. To determine which doors are secured, a
conversion process must be applied to each digit in that hexadecimal value.
Each hexadecimal digit in the status of doors field represents four doors. Working from right-to-
left, the first digit represents doors 1 through 4, the second digit represents doors 5 through 8,
and so on to the eighth digit representing doors 29 through 32.
Each hexadecimal digit must be converted to binary to determine specifically which doors are
secured. Again, working from right-to-left, convert the hexadecimal digit to its binary value. The
first digit in the binary value refers to the first door in the group (i.e. a group of doors 5 through 8,
the first digit would refer to door 5), the second digit refers to the second door (6), the third digit to
the third door (7), and the fourth digit to the fourth door (8). Wherever there is a zero in the binary
value, that indicates the corresponding door is secured.
To simplify this process, a table, breaking down this conversion process is provided in Appendix
1. By working the status of doors value through the table in Appendix 1, you can easily determine
which doors are secured.
Responding Nodes identifies how many and which controllers are responding to the network in a
manner similarly to the status of doors value. An eight digit hexadecimal value is displayed in the
responding nodes field. To determine how many and which controllers are responding, a
conversion process must be applied to each digit in that hexadecimal value.
Each hexadecimal digit in the responding nodes field represents four controllers. Working from
right-to-left, the first digit represents controllers 1 through 4, the second digit represents
controllers 5 through 8, and so on to the eighth digit representing controllers 29 through 32.
Each hexadecimal digit must be converted to binary to determine specifically which controllers
are on-line and active. Again, working from right-to-left, convert the hexadecimal digit to its binary
value. The first digit in the binary value refers to the first controller in the group (i.e. a group of
controllers 5 through 8, the first digit would refer to controller 5), the second digit refers to the
second controller (6), the third digit to the third controller (7), and the fourth digit to the fourth
controller(8). Wherever there is a one in the binary value, that indicates the corresponding
controller is responding to the network.
