T1-T2-T3-T4

13.2

Physical Interface



RS485 asynchronous half-duplex Communication mode.



Default data format of communication terminal ofkeypad: 1-8-N-1rbits rate: 9600bps.



Default data format of RS485 terminal: 1-8-N-1ofe. rmat, with sing



Data format 1-8-N-1, 1-8-O-1, 1-8-E-1, optional bits rates 4800bps, 9600bps,
19200bps, and 38400bps

The parity in ADU (Application Data Unit) is obtained via the CRC16 parity of the 1

three

parts of ADU and switching the low bytes and high bytes. Low bytes of CRC parity go first,
and high bytes of it follow in the protocol format.
