at a Moore 352Plus or Moore 353 Display Assembly's MMJ-11 connector, or a Moore 354 or 354N Controllers'
DB9 display/configuration port, is RS232 and uses an address of 1.
The Cycle Time of the station can be viewed as a parameter within the STATN block. In addition, a bias can be
added to increase the total cycle time of the station. This may be necessary when significant communications
activities are taking place, causing communication overrun errors. Adding bias will allow the processor more time
during each scan cycle for completing the communication chores.
The station can be configured to time out of the configuration mode after 1 minute of no faceplate operations by
setting the CONFG TO parameter to YES (default). This parameter is in firmware versions 1.30 and higher.

A list of the installed controller hardware and software can be viewed within the STATN block using the HW PRES
read only parameter. As shown in Table 3.3, each board has an ID and a hardware revision, and most also have a
software revision. The controller's operating Kernel and operating code reside on the MPU Controller board and
there is an entry in the table for each. The table lists the hardware and software revisions. For example, in Table
3.3, the MPU Controller board would be shown in the numeric display as '11 1.00'.

Check the NVRAM battery condition by reading the BAT OK parameter. The NVRAM, on the MPU Controller
Board, uses a sealed lithium battery that has a life of up to 40 years.
stores operating data when external power is removed from the controller. When external power is next applied, the
controller will read this data and return to the stored operating conditions. Should the battery fail, the station will
power up in a Cold start using the controller configuration stored in permanent FLASH memory. Battery condition
has no effect on normal operation while external power is applied. The SERV PIN is used when a LonWorks board
is installed to identify this controller to the LonWorks network manager.

With the Real Time Clock jumper properly set, as described in Section 9, up to 40 years for an on-line controller or for a stored MPU
Controller Board or controller.
Up to 4 years for a stored MPU Controller Board or controller with the Real Time Clock jumper improperly set (i.e. clock enabled).
Environmental conditions can affect battery life.

1. No handshaking is used.
2. The station port will turn on the RTS line when it's ready to send data but will
not wait for a responding CTS from the receiving device.
3. The station port will turn on the RTS line when it's ready to send data and will
wait for a responding CTS from the receiving device before transmitting.
