SECTION 10 – MAINTENANCE
YorkTalk 2 Communications
Received Data (Control Data)
The unit receives 8 data values from the MicroGate-
way or E-Link. The first 4 are analog values and the
last 4 are digital values. These 8 data values are used as
control parameters when in REMOTE mode. When the
unit is in LOCAL mode, these 8 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 36 “YorkTalk 2 Communications Data Map”
lists the control parameters. These values are found un-
der 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 Equipment In-
tegration website.
