SECTION 10 – MAINTENANCE
Received Data (Control Data)
The unit receives eight data values from the MicroGateway
or E-Link. The first 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.
YORKTALK 2 COMMUNICATIONS
Transmitted Data
After receiving a valid transmission from the MicroGateway
or E-Link, the unit will transmit either operational data or his-
tory 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 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 -
ment Integration website.
