YorkTalk 2 Communications

Received Data (Control Data)
The unit receives eight data values from the MicroGate-
way or E-Link. The first four are analog values and the
last four are digital 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 YorkTalk 2
transmission for 5 minutes it will revert back to all lo-
cal control values. Table 36 "Yorktalk 2 Communica-
tions Data Map" lists the control parameters. These
values are found under feature 54 in the MicroGateway
or E-Link.

Transmitted Data
After receiving a valid transmission from the Micro-
Gateway or E-Link, the unit will transmit either op-
erational data or history buffer data depending on the
"History Buffer Request" on ENG PAGE 10. 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. Table 36 "Yorktalk 2 Communications Data
Map" shows the data values and page listings for this
unit.
The latest point map information is
listed on the Johnson Controls Equip-
ment Integration website.
