2.2 RS-232 baud rate setting.
Baud rates can be set in the DVR, the baud rate selections including
2400, 4800, 9600, 19200, 28800, 38400, 57600 and 115200.
2.3 The maximum number of text information records.
For every 10.24 Giga bytes of hard disk capacity, the DVR reserves space for
32768 text records. Each hard disk keeps its own data in itself. In a DVR with two
hard disks, the user can remove any one of them, and the remaining one will keep
working.
For example, in the case of an 80G hard disk, the maximum number of recorded
text information is ( 80 / 10.24 ) x 32768 = 196608.

Each text information contains up to 100 characters.
