DATA PAIR 1
DATA PAIR 2
1. TWO INDEPENDENT DATA PAIRS MUST BE USED FOR THE RS-485 NETWORK. BOTH PAIRS MUST BE ROUTED SO TO ALWAYS BE IN SEPARATE CONDUITS.
NOTES:
TB7
2. THE MAXIMUM LENGTH OF EACH RS-485 LOOP MUST NEVER EXCEED 4000 FEET (1219 METERS).
3. USE MINIMUM 24 AWG TWISTED PAIR WITH SHUNT CAPACITANCE OF 16pF PER FOOT AND 100 OHM CHARACTERISTIC IMPEDANCE. FOR INSTALLATIONS UNDER ADVERSE CONDITIONS (FOR EXAMPLE
WHERE HIGH ELECTRICAL NOISE IS EXPECTED), THE USE OF TWISTED SHIELDED PAIRS IS RECOMMENDED.
4. WHEN USING TWISTED SHIELDED PAIRS, FOR EACH PAIR, THE SHIELD MUST ONLY BE TERMINATED AT THE GROUND LUG ON THE LEFT SIDE OF TB 7 ON THE MCP. FOR INTERMEDIATE UNITS, THE SHIELD
FROM THE INCOMING PAIR MUST BE CONNECTED TO THE SHIELD OF THE OUTGOING PAIR SO AS TO BE CONTINUOUS THROUGHOUT THAT LOOP. THE SHIELD ON THE LAST UNIT MUST BE CUT SHORT AND
LEFT FLOATING.
5. MODULE 1 (ALWAYS THE MCP) AND MODULE N (LAST UNIT) MUST HAVE EOL LINKS FITTED (AS SHOWN BELOW) WHILE ALL OTHER MODULES MUST NOT.
