Elevator Car Communication Board RS32 – The Silent Guardian of Every Ride

Every flick of the position indicator, every chime, and every emergency call is only possible because a postcard-sized PCB is translating data at 125 kbit/s between the car top and the machine-room controller. The RS32 Car Communication Board—originally designed for Otis Gen2® and now adopted by more than twenty global OEMs—handles this invisible conversation 24 hours a day. Nanjing Zhuye Elevator Parts keeps factory-sealed RS32 units on the shelf for same-day despatch. Below we explain what the board does, how to install it in under eight minutes, and the replacement cycle that turns expensive “communication fault” callbacks into a five-minute planned task.
-
What the RS32 Board Actually Does Mounted on DIN-rail inside the car top box, the board:
-
Converts parallel button presses into serial CAN-bus frames
-
Drives floor indicators, arrows and buzzers through a 40-pin ribbon
-
Provides 24 VDC / 5 VDC rails for COP accessories
-
Monitors emergency battery voltage and triggers alarm buzzer if <21 V
-
Stores floor parameters in 256 K EEPROM so the car “remembers” after a power dip
If RS32 fails, the cab goes dark, the doors refuse to move, and the controller logs “EF3 Car Com Lost”.
-
Compatible Systems
-
Otis Gen2®, Gen2-Life, SkyRise®
-
Thyssen MC2 → MC3 retrofit
-
Chinese MRL controllers with CAN-open protocol
-
Simplex or group (≤8 cars)
-
Installation – 8-Minute Hot Swap Safety: place controller on INSTALL, lock breaker, wait 60 s for DC bus to discharge.
Step 1 – Photograph existing wiring. Step 2 – Undo four M3 screws; slide board out of DIN rail. Step 3 – Disconnect 40-pin ribbon, 4-way CAN, 2-way 24 V supply. Step 4 – Inspect ribbon for bent pins; replace if damaged (Nanjing Zhuye part WR-40-250). Step 5 – Insert new RS32 until latches click; reconnect keyed plugs. Step 6 – Power up; green D1 blinks 2 Hz for 3 s, then steady—board is on-line. Step 7 – Run one full learn trip; verify floor indicator counts correctly. No laptop or download required; firmware is pre-flashed.
-
Daily Operation
-
Scans 64 buttons every 20 ms; debounce 40 ms
-
Auto-dims LEDs to 30 % after 22:00 (energy code)
-
Temperature sensor derates CAN speed above 70 °C
-
Audio output 200 ms, 24 VDC for gong
-
Replacement Cycle
-
High-traffic (>1,000 starts/day) – inspect every 6 months, replace every 5 years
-
Residential (300–600 starts/day) – inspect annually, replace every 8 years
-
Low-rise freight – inspect every 18 months, replace every 10 years
Replace immediately if:
-
D1 LED stays red
-
CAN “EF3” logged ≥3 times in 30 days
-
Position indicator skips or shows “––”
-
EEPROM error 0xF0 after power dip
-
Pro Tips for Longer Life
-
Keep 24 VDC ±3 %; spikes >30 V kill on-board buck
-
Close top box; condensate is the #1 killer
-
Route ribbon away from brake resistor; heat >70 °C halves life
