This web interface can be used on site or remotely via network communications. Digital fault and leak relay outputs and a 4-20mA relay output and allow the LD5200 to interface with third-party management systems. The LD5200 also provides Modbus outputs via EIA-485, twisted-pair wire, or TCP/IP, as well as BACnet/IP or BACnet/MSTP, SNMP, and SMTP outputs.
Page 15: Installation

A 15-foot (4.57m) section of non-sensing cable is supplied with each LD5200. The leader cable connects sensing cable to the LD5200, since sensing cable cannot connect directly to the unit. Insert its four stripped wires into the appropriate slots in TB2 - from left to right: white, black, green and red.

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.
Page 21: Connect The Seahawk Sensing Cable
To avoid faulty leak detection readings, connect a minimum length of 35 feet (10.7m) of sensing cable to the LD5200. The LD5200 is shipped with a 15-foot (4.57m) leader cable. This leader cable was connected to the LD5200 in Section 2.3.2 on page 18.

Page 24: Test The System
Installation Test the System If the LD5200 is already connected to a BMS or NMS, notify monitoring personnel before you Note begin testing the system. Using a sketch or mechanical drawing of the facility, add the cable routing, connection points, and any accessories used. Record the distance marker when the cable changes direction and in between connectors.
Page 25: Calibrate Cable Resistance
A system configured using base resistance values will still be very accurate. If you wish to fine tune the resistance value of your LD5200 system to make it more precise, you may do so. This will increase the accuracy of the system, and bring the LD5200’s reported installed cable length value in line with the actual length of cable installed.

When using the leak detection master option, the LD5200 relays can be activated according to the slave unit alarm. If the slave has a leak alarm or a cable break alarm, the LD5200 leak or cable relay will change state, respectively (i.e. it will trigger that an alarm is present). The zone will then appear on the LCD and an alarm state will be reported to the top level of the system.
Page 88: Implementation Basics
5.3.1.2 Function Field The function field is one byte in length and tells the LD5200 which function to perform. The supported functions are 03 (Read 4xxxx output registers), 04 (Read 3xxxx input registers), 06 (Preset single register) and 16 (Preset multiple registers).
Page 89: Error Check (Checksum) Field
The LD5200 RTU mode uses a 16-bit cyclic redundancy check (CRC-16). Exception Responses If a Modbus master sends an invalid command to the LD5200 or attempts to read an invalid register, an exception response is generated. The response packet will have the high order bit of the function code set to one.

Make sure the EIA-232 port is connected to a PC or terminal with a straight through cable (not provided). Run terminal emulation software (i.e., HyperTerminal) and make sure the settings match the LD5200 EIA-232 port configuration; refer to “P1: EIA-232 Connector” on page 19 for port configuration details. When the LD5200 is powered up, diagnostics are performed.
