The JA-121T BUS RS-485 interface

Model example:
1*1234 SET 1 2
(set sections 1 and 2)
2*4321 PGOFF 5 6
(turn off PG 5 and 6)
When the syntax has been entered correctly and if the sections
were not set before, the returned answer will be:
STATE 1 ARMED
STATE 2 ARMED
OK
According to this example it can be seen that the command has
been done successfully so sections 1 and 2 have been set and
the command was correct (OK).
If at least one section of the defined range has already been
previously set, then it sets the rest of the sections. When section
1 is already set, the returned answer will be:
STATE 2 ARMED
OK
If an entered command is found to be correct, but with invalid
authorisation, the returned answer will be:
ERROR: 3 NO_ACCESS
If the system was not able to execute any of the commands
(for example when all sections are already set) the returned answer
will be:
ERROR: 4 INVALID_VALUE
To an incorrectly entered command, the returned answer will be:
ERROR
Basic statuses of the sections:
STATE <section> <status>
Example:
STATE 1 READY

A status of individual devices is returned after the PRFSTATE
command or automatically every 10 seconds according to the
Passive mode
. A conversion of the numerical sequence from HEX
form to BIN has to be performed. This numerical sequence consists
of 14 characters for the JA-101K control panel, 32 characters for
the JA-106K control panel and 60 characters for the JA-103K and
the JA-107K control panels.
Example:
PRFSTATE 289600000800000800000A0000008000
According to the figure 2 below we can see, after conversion to
the BIN format, which devices are triggered. The active devices are
no. 3, 5, 9, 10, 12, 15, 35, 59, 81, 83 and 119.

U1-A mode – function description
(customer’s settings)
The events are converted to the set U1-A mode code, it is visible
as another ARC – concerning the radio communication module
(F-Link sets up a new way of communication). When no U1-A
device is connected and no data packets are transferred between
the system BUS and the U1-A system, a communication error is
triggered (fault of U1-A communicator).
Setting the module properties
The
Internal settings
option at the module position in
the
Devices
tab in the F-Link software opens a dialogue window
where you can set the following options for each output:
Device basic mode:
Terminal / U1-A – for use with a smart
home choose Terminal.
TMP terminal:
Enabled / Disabled / Inverted – factory default NC
can be changed to NO.
Motherboard button:
Enrolling button / Tamper contact
Period after which a fault is triggered [min]:
When an external
communication fault is triggered it generates a fault in a pre-set
time.
Connection confirmed:
Every 10 s / Disabled – determines if
the communication with the RS-485 serial line is confirmed or not.
Passive mode:
In the passive mode the RS-485 serial line only
receives the data, but sends them only on request (by relevant
commands).
The manufacturer only guarantees correct
functioning of the module. However, they
cannot guarantee the correct functioning
of the connected device on the serial line.
