OVERVIEW
The SC-EQUIP (SC-EQ) Communication Card super-
sedes the E-Link Gateway and provides BAS network
connectivity for Johnson Controls® and YORK® me-
chanical equipment, such as chillers and rooftop units.
It is designed with four active serial ports: The J12
BAS (RS-485) port, the J7 Equipment (RS-232) port,
the J8 Equipment (RS-485) port and the J11 CS port
which allows equipment data to be sent to the Johnson
Controls Remote Operation Center for remote chiller
monitoring and diagnostics.
To simplify the installation and setup, the SC-EQ
Comm Card automatically determines the BAS proto-
col and Baud rate and the model of the connected chill-
er or rooftop unit. The only user setting is the MAC
address for the SC-EQ on the BAS network.
Several SC-EQ Comm Card models are available
for connection to various types of input voltage and
equipment. For chillers using the OptiView™ 02430 or
03630 microboards, the SC-EQ Comm Card consists
of a single circuit board attached to four studs inside
the Micro Panel, using the accessory mounting kit. The
microboard supplies 12 VDC input power, eliminating
the need for an external power supply. The SC-EQ plug
J10-COM needs a ground wire to ground the lug on the
panel.
For screw compressor chillers using the 02478 or 03478
microboards, the SC-EQ Comm Card is installed inside
the Micro Panel, using the accessory mounting kit. The
microboard supplies 12 VDC input power, eliminating
the need for an external power supply.
For scroll compressor chillers using the 02050 or 02550
microboards, the SC-EQ Comm Card is installed in-
side the Micro Panel and requires an additional trans-
former to supply power to the SC-EQ Comm Card. The
transformer is included in the SC-EQ Scroll Chiller In-
stallation Kit.
For other types of chillers, the SC-EQ Comm Card is
packaged in its own enclosure. In addition to the SC-
EQ circuit board, a transformer is included inside the
enclosure that converts a 120 VAC or 240 VAC input
to 24 VAC power.
