Each slave drive must be assigned a unique slave address for serial communications to work. Slave addresses do not need to
be assigned in sequential order, but no two drives may share the same address.
n
H5-02: Communication Speed Selection
Sets the communications speed for APOGEE FLN, BACnet, MEMOBUS/Modbus, and Metasys N2.
Note:
1.
Cycle power for the setting to take effect.
2.
When Metasys N2 communications are selected (H5-08 = 1), selecting a baud rate other than 9600 bps will trigger an oPE29 error.
3.
When APOGEE FLN (P1) communications are selected (H5-08 = 2), selecting a baud rate other than 4800 bps will trigger an oPE29
error.
4.
When BACnet communications are selected (H5-08 = 3), selecting 115200 bps (Setting 8) will trigger an oPE29 error.
