Connecting ARCs to Jupiter hardware is simple using the (RJ-45) ARC port on either the front or back of the device. These ports not only provide communication (RS-485) data, but also +24 VDC power. If the required number of ARCs exceeds the current limits of the Jupiter ARC port(s), an ARC-PS can be used to power additional ARCs. Connecting a Jupiter ARC port to the RS-485 port on the ARC-PS is easily accomplished by following one of two methods.
Method 1: Modify an Off-the-Shelf CAT-5 cable
- Cut off one end of the CAT-5 cable.
- Wire three of the wires to a terminal block connector such that:
A = Blue.
B = Blue/White.
Ground = Green.
Note: Blue/White is twisted with Blue, and Green/White is twisted with Green. - Connect the RJ-45 to the ARC port on Jupiter.
- Connect the terminal block connector to the RS-485 port on the ARC-PS.
- Connect your ARCs to the RJ-45 ports on the ARC-PS.
- Program your ARCs with the External Controller Wizard in the Jupiter software.
Method 2: Make Your Own Cable
- Crimp an RJ-45 connector to one end of a CAT-5 cable.
Note: Only pairs 4+5 and 3+6 are necessary, so STP cable could be
substituted by sharing the ground. - Wire three of the wires to a terminal block connector such that:
A = pin 4.
B = pin 5.
Ground = pins 3 and 6. - Connect the RJ-45 to the ARC port on Jupiter.
- Connect the terminal block connector to the RS-485 port on the ARC-PS.
- Connect your ARCs to the RJ-45 ports on the ARC-PS.
- Program your ARCs with the External Controller Wizard in the Jupiter software.
