PAC ARChive <on | off> – This setting is for Wireless Matrix configuration only. The
default is ON and it should be left ON.
PAC POW <0…> – Pause on wake-up. This setting delays the PAC from polling for a set
amount of time in seconds. This is used to provide transmitters time to stabilize when using
the PAC on-board I/O. This setting is also used when the communication device needs a
delay to "key up" after receiving DTR.
WRite – Save the current settings in non-volatile memory so they are available the next time
the PAC powers up.
Version – Display the current PAC firmware version and list the drivers that are available.
Note that each driver has a separate version number.
RTU <open | close> – Open or close the RTU driver.
ZAP – This command will erase the PAC configuration and I/O point list from non-volatile
memory. The PAC will boot with a default configuration unless a WRITE command is
issued before the PAC is powered down.
ZAP cfg – This command only erases the configuration of the PAC.
ZAP gdn – This command only erases the I/O point database list in the PAC.
Poll <pid> – PAC will poll the specified poll-set <pid>.
REPort <pid> – PAC will send report for the specified poll-set <pid>.
DOWNLOAD – This command is used to upgrade the PAC firmware. Do not use this
command unless you have the tools to upgrade the PAC firmware. Cancel by command by
cycling power to the PAC prior the starting the code download.
3.3 I/O Point Database
The PAC maintains a list of all the I/O points it needs to access. Each point can have alarms
associated with it. See the sections on alarms. PAC version 2.1x and later can access up to
340 I/O points. I/O points are usually added remotely through the GDN but points can be
added locally. Each I/O point has a list of parameters associated with it. The parameters
define the context the PAC needs to access the I/O point correctly. Two parameters, poll-set
ID (PID) and index are common to all I/O points. The remaining parameters are specific to
the driver. Some I/O points are internal to the PAC.
The poll-set ID is a reference number used to group I/O points. Poll and report events are
based on the poll-set ID. For example, all I/O points with poll-set id 1 are a group and will
be polled and reported together. Valid poll-set ID numbers are 1-254 (255 is reserved for
internal points).
