Yorktalk 2 Communications
Received Data (Control Data)
The unit receives eight data values from the Micro-
Gateway 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 RE-
MOTE 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.
“Yorktalk 2 Communications Data Map” lists the con-
trol 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
Table 31 on page 156 “Yorktalk 2 Com-
munications Data Map” shows the data values and
page listings for this unit.
The latest point map information is listed
on the Johnson Controls Equipment In-
tegration website.
