Baud rate settings for the RS-232 port and the RS-485 port are both set through this dip switch. The RS-
232 baud rate is set with switch positions 1 and 2. The RS-485 baud rate is set with switch positions 3 and
4.
2-7.2.1 SW2, Positions 1 & 2
The manufacturer sets the baud rate of the RS-232 connection to 9600 baud. Manipulating the positions of
switches 1 and 2 adjusts the baud rate as follows:
21 (Switch position)
01 = 1200
10 = 2400
00 = 9600
11 = 19,200
2-7.2.2 SW2, Positions 3 & 4
The manufacturer sets the baud rate of the RS-485 connection to 9600 baud. Users can set the baud rate
using SW2, positions 3 and 4, and manipulating them as follows:
43 (Switch position)
00 = 1200
10 = 9600
01 = 2400
11 = 19,200
2-7.2.3 SW2, Position 5
SW2, position 5 enables or disables the LCD.
0 = Disable
1 = Enable
2-7.2.4 SW2, Position 6-8
SW2, positions 6 through 8, designate the length of cable attached to the LD5000. This insures the 4-
20mA output readings are correct for the LD5000 system. Without an accurate length setting, the unit
would not return the proper 4-20mA reading to diagnose the condition of the cable.
Switch settings are listed below. If the length of cable falls between two amounts, use the settings for the
higher of the two amounts:
876 (Switch position)
000 = 0 - 500 ft. (0 - 152.4 m)
001 = 0 - 1000 ft. (0 - 304.8 m)
010 = 0 - 1500 ft. (0 - 457.2 m )
011 = 0 - 2000 ft. (0 - 609.6 m)
100 = 0 - 2500 ft. (0 - 762.0 m)
101 = 0 - 3000 ft. (0 - 914.4 m)
110 = 0 - 4000 ft. (0 - 1219.2 m)
111 = 0 - 5000 ft. (0 - 1524.0 m)
2-7.3 SW4 - Termination Setting
SW4-1 is used to set termination on the unit. ON (down) indicates termination and OFF (up) indicates no
termination.
