Received Data (Control Data)
The unit receives eight data values from the MicroGateway
or E-Link. The rst four are analog values and the last four
are digital values. These eight data values are used as con-
trol parameters when in REMOTE mode. When the unit is
in LOCAL mode, these eight values are ignored. If the unit
receives no valid YorkTalk 2 transmission for 5 minutes it
will revert back to all local control values. Table 32 “Yorktalk
2 Communications Data Map” lists the control parameters.
These values are found under feature 54 in the MicroGateway
or E-Link.

or E-Link, the unit will transmit either operational data or his-
tory buer data depending on the “History Buer Request”

under feature 54. If there is no value to be sent to a particular
page, a zero will be sent. Table 32 “Yorktalk 2 Communica-
tions Data Map” shows the data values and page listings
for this unit.
The latest point map information is
listed on the Johnson Controls Equip-
