E-Link Gateway Installation Instructions
13
APP Group B
APP Group B uses a 4-way DIP switch to select the
desired output protocol. This switch is also binary
weighted, allowing up to 15 unique selections.
Push Button
The E-Link Gateway uses a push button (Figure 11) as
a means of activating any user selections on APP
Group A and APP Group B switches.
Note:
Refer to the
E-Link Gateway Commissioning
and Troubleshooting Technical Bulletin
(LIT-12011238)
for more details.
Equipment Configuration
Different pieces of equipment sometimes require a
specific hardware configuration (jumper/switch
settings) to enable communication with the E-Link
Gateway. Refer to the equipment’s installation literature
for the proper configuration settings.
Setting the Rotary Switch on Chiller Panels
Some Micro Panels use a rotary switch to set their
YORK Talk II address (YORK Talk address = Rotary
Switch s 1). Since the E-Link Gateway uses a
one-to-one relationship with the chiller panel, this
switch is normally set to 0 (YORK Talk address 1).
However, in a master/slave configuration, set the
master Micro Panel rotary switch to 0, and the slave
Micro Panel to 1. If the chiller Micro Panel is not
equipped with a rotary switch, the YORK Talk address
may be set using the Micro Panel keypad. In most
cases, you can configure the setting, but some models
are fixed and cannot be changed (refer to the
equipment documentation for specific details).
Network Topology
The E-Link Gateway has three serial communications
ports and an optional
L
ON
W
ORKS
port to connect
equipment to a BAS system. Port 1 and Port 4 are
designed as the BAS ports, with Port 1 used to support
all RS-485 based communication protocols, and Port 4
used for
L
ON
W
ORKS
connectivity with the addition of a
L
ON
W
ORKS
ProtoCessor module.

See
Figure 24 and Figure 25 for additional
