Wireless TEC Transceiver (TTX)
Item Number 129-319, Rev.CA Page 1 of 2
Product Description
The Wireless Terminal Equipment Controller (TEC)
Transceiver (TTX) communicates with the Wireless
Room Temperature Sensor (RTS) and uses radio
frequency hopping technology. The TTX surface
mounts near the TEC via a bracket.
Product Numbers
550-205 TEC Transceiver, mounting bracket and
hardware, two power connectors, and
RJ11 to RJ11 communications cable
Accessories
540-143 Laptop cable (RJ11 to DB9)
550-200 Replacement communications cable
(RJ11 to RJ11)
550-710 Isolation transformer, 1:1,
(24V in; 24V out) *
550-074 Fitting for optionally mounting
antenna through a knockout (5 pack)
NOTE: 3M Scotchlok™ power connectors are
available from W.W. Grainger, Inc. (part
number 4YT73) via the Field Purchasing
Guide.
* When TTX/TEC is powered off a main
transformer that is different from the field panel
main transformer, then a ground loop could
potentially occur and necessitate the user of an
isolation transformer for the TTX.
