16 SUPERVISION
The pCO1 and pCO2 can be connected to a local or remote supervisor PC, via a GSM or analogue modem, as well as to the more commonly-used
BMS (Modbus, Bacnet, Lonworks). The use of the functions listed requires the installation of specific optional cards (RS485, RS232, LON) or
Gateways (devices that convert the different communication protocols).
16.1 CAREL SUPERVISOR
The local connection between the pCO1– pCO2 board and a supervisor PC requires the installation of the additional RS485 card (pCO2:
PCOSER48500; pCO1: PCO1004850) in the “Serial card” slot. The 3-wire RS485 line is then made from the screw connector on the additional card
to the RS485/RS232 converter supplied by Carel (PC485KIT00) for connection to the PC.
For a remote connection to the supervisor PC by phone line, simply fit the optional RS232 card (pCO2: PCO200MDM0; pCO1: PCO100MDM0)
and connect it to a standard modem (not GSM). The program manages the modem and allows the desired phone numbers to be set. For the
connections refer to the instruction sheets.
16.2 BMS
There are various different connections to the BMS supervisor systems.
Lonworks: fit the additional card in the “Serial card” slot (pCO2: PCO20LFTTL / PCO20L485L; pCO1: PCO10LFTTL / PCO10L485L) and make
the connections, referring to the instruction sheets. On the LCD terminal enable the LON function.
Modbus: fit the additional RS485 card; no other steps are required as the program automatically manages this protocol.
Bacnet: fit the additional RS485 card and connect it by an RS485 cable to the Carel gateway, code GATEWAYBN0.
Proprietary BMS: Carel has developed many other Gateways for interfacing to less common BMS, such as OTE.
16.3 GSM PROTOCOL
Selecting the GSM protocol allows SMS (text) messages to be sent to and received from GSM telephones, using a GSM modem. The pCO1 or pCO2
send messages to the telephone in the event of alarms, and can receive messages from the telephone at any time; in fact, with a GSM telephone the
user can modify the parameters listed below (for more information, refer to the Carel GSM modem protocol manual, code +030220330):
