SECTION 6 - OPERATION
BAS COMMUNICATIONS
YORK Talk 2 Communications
Received Data (Control Data)
The unit receives eight data values from the E-Link
Gateway as shown in
. The
first four are analog values and the last four are digi-
tal values. These eight data values are used as control
parameters when in REMOTE mode. When the unit is
in LOCAL mode, these eight values are ignored. If the
unit receives no valid YORK Talk 2 transmission for
five minutes, it will revert back to all local control val-
ues. The YVWA Communications Data Map lists the
control parameters.
Transmitted Data
After receiving a valid transmission from the E-Link
Gateway, the unit will transmit operational data or his-
tory buffer data depending on the HISTORY BUFFER
REQUEST. Data must be transmitted for every page
under Feature 54. If there is no value to be sent to a
particular page, a zero will be sent to the YVWA Com-
munications Data Map.
The most current data map information
is listed on the Johnson Controls/York
Equipment Integration web site or
. The map is YVWA BAS 1 Circuit.
A reboot is required (cycle power) after
the settings are changed.
