2.3.8 SW2: TB6 Port 2 (Bottom Row) Termination Switch
The switch position numbered 2 on SW2, when switched on (down position), places a
termination resistor across the + and - terminals of the EIA-485 port. This is used when the
TB6 (bottom row) connection on the LD5200 is the last unit on a EIA-485 network. SW2,
switch position 1, is currently inactive.
2.3.9 SW3: TB6 Port 1 (Top Row) Termination Switch
The switch position numbered 2 on SW3, when switched on (down position), places a
termination resistor across the + and - terminals of the EIA-485 port. This is used when the
TB6 (top row) connection on the LD5200 is the last unit on a EIA-485 network. SW3, switch
position 1, is currently inactive.
2.3.10 P2: RJ45 Network
This 10/100 BaseT Ethernet connection allows the LD5200 to be connected directly to a local
area network. Use a crossover cable (shipped with the LD5200; blue cable with yellow ends)
for initial connection and configuration. The default settings are as follows:
IP Address: 10.0.0.188
Subnet Mask: 255.255.255.0
Default Gateway: 10.0.0.1
2.3.11 P3: Optional Power Connection
If a mechanical failure causes the provided AC power supply and connections to fail, a wall
adapter can be plugged into P3 and used to power the LD5200. This option is provided for
temporary, emergency situations only, and is not intended as a permanent power solution.
2.3.12 TB7: Input Power (from Input AC Power Supply)
TB7 is a factory-wired two position connector with the following connections (for reference
only):
TB7-1 24VDC positive (+)
TB7-2 24VDC negative (-)
2.3.13 DS1: Status LED
A status LED is located at the top of the main board, and is labeled DS1. Indicators are as
follows:
Green - LD5200 is functioning properly
Red - LD5200 is in an alarm state
Yellow (flashing) - The LD5200’s bootloader is operational
