SECTION 7 – UNIT CONTROLS
Yorktalk 2 Communications
Received Data (Control Data)
The unit receives eight data values from the E-Link
Gateway. 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 ig-
nored. If the unit receives no valid YorkTalk 2 trans-
mission for 5 minutes it will revert back to all local
control values. Table 18 on page 145 lists the control
parameters. These values are found under feature 54 in
the E-Link Gateway.

Transmitted Data
After receiving a valid transmission from the E-Link
Gateway, the unit will transmit either operational 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
18 on page 145 shows the data values and page list-
ings for this unit.
