For general handling information on the GT Series, refer to the GT-series User's
Manual.
● Connecting GT12 Series to HL-G1 (More than a single HL-G1 unit over
RS-485)
• Up to four HL-G1 units can be connected.
• The console will be the terminator. Connect the ground terminal "E" to the signal
"-RD".
• Set the "Terminating resistor selection" for the terminating HL-G1 unit only,
while turn OFF the terminating resistor for each intermediate HL-G1 unit
connected through a bus line.
• The shield of each HL-G1 extension cable is connected to the signal ground (SG)
of the sensor head. Connect the shield to the 0 V (-) terminal of the power supply
for the console.
Wire the SD and RD signal lines according to the diagram as shown
below.
(+SD and -SD are connected with a twisted pair cable and so are
+RD and -RD.)
• Short-circuit the +SD + RD terminals and -SD and -RD terminals.
• Connect the +SD and +RD terminals on the HL-G1 side and the
+SD and +RD terminals on the console side.
• Connect the -SD and -RD terminals on the HL-G1 side and the -SD
and -RD terminals on the console side.
