Power Supply
The power supply connector (TB19) is a
dual two pin connector. Either connector
allows for power in (pin #1 (+), pin #2 (–)
and bussing of power to other NGC-30-CRM
modules).
Note: Power supply must be sized correctly
based on the number of NGC-30-CRM/-CRMS
modules.
RS-485 Communications
The RS-485 connector (TB6) is a dual three
pin connector. Either connector allows for
RS-485 input signals (pin #1 (shield), pin #2
(+), pin #3 (–)) and bussing of RS485 signal
to other NGC-30-CRM modules.
End of Line (EOL) Jumper
If this device (NGC-30-CRM/-CRMS) is the last
device in the RS-485 network, the J1 jumper
needs to be moved from terminals 2 & 3 to
terminals 1 & 2.
