3. COMMUNICATION PORTS
3.1 Serial ports
Compared to the pCO3, pCO5+ (and pCO5) controllers have a second
BMS serial port on connector J25 (BMS2) and a second Fieldbus port
on connector J26 (FBus2). pCO5+ Large and Extralarge boards still have
connector J23, which is marked FBus2 like connector J26. With reference
to management under 1Tool, this is the same serial line, so diff erent
addresses must be used for devices connected to both connectors,
while from the electrical point of view the ports are independent (an
electrical fault on port J26 does not aff ect port J23). See the “Technical
Specifi cations” table.

Serial Type/Connector Features
Serial ZERO pLAN/J10, J11
• Built into main board
• HW driver: asynchronous half duplex RS485 pLAN
• Not optically isolated
• Connectors: telephone jack + 3-pin plug-in connector
Serial ONE BMS 1 Serial Card
• Not built into main board
• HW driver: not present
• Can be used with all the BMS expansion cards of the pCO family
Serial TWO FieldBus 1 Serial Card
• Not built into main board
• HW driver: not present
• Can be used with all Fieldbus expansion cards of the pCO family
Serial THREE BMS 2 / J25
• Built into main board
• HW driver: asynchronous half duplex RS485 slave
• Optically-isolated/non-optically-isolated serial
• 3-pin plug-in connector
Serial FOUR FieldBus 2 / J26
(and J23 on Large and
Extralarge versions)
• Built into main board
• HW driver: asynchronous half duplex RS485 Master or Slave (see par. 3.2)
• J23: not optically isolated
• J26: optically isolated/not optically isolated
• 3-pin plug-in connector
• J23 and J26 are both managed by the same protocol as serial 4, with the advantage of being electrically
independent.
