33. IS15 Instrument System
In systems with 9-15 instruments, please observe:
Avoid mounting a main system head and a repeater head adjacent - a minor delay in response will be observed on the repeater
Start with the main system when commissioning
Repeat the procedure on the repeater system
Perform calibrations on the main system and enter the calibration values into the repeater system
Normal operational settings, e.g. alarms, damping and illumination must also be set on the repeater system
You can only turn the depth sounder off on the main system

Observe instructions when connecting NMEA cables to
Instruments
Expander
Follow instructions carefully at first time turn on
Do not forget to turn off the Roblink when installing a single instrument as NMEA repeater

37. IS15 Instrument System Roblink cable lengths 1.
Total length of Roblink cables on one port is limited to 30m (100’) *
IS15 Transceiver has one port with two connectors for the instruments: J1,J2
Observe the total cable lengths and use both connectors on Transceiver when practical
Cable length from wind transducer (MHU) not to be included

38. IS15 Instrument System Roblink cable lengths 2.
IS15 Expander has two ports and four connectors for the instruments: J1(port one) and J2,J4,J5 (port two)
The maximum number of instruments on one port is 7
A total of 8 instruments can be connected
Connect/interconnect the instruments in the most practical way
Keep in mind the cable length and number of instruments on each port

39. IS15 Instrument System Instrument connections
Four identical two pin connector sockets
Each socket is identified by number and signal markings
Power (1) and Roblink (2) connections may be interchanged unless otherwise stated in installation instructions

45. IS15 NMEA Interface Input/Output NMEA sentences 1) Recommended 2)
Transducer offset is local in IS15, hence offset in DPT input sentence is ignored.
Recommended 2)
This sentence not required with Transceiver or Expander in the system.

46. IS15 NMEA Interface
IS15 Expander NMEA interface

47. IS15 NMEA Interface NMEA connections
The instrument port is unidirectional (in or out )
It is automatically configured as listener when hearing a talker
NMEA input (from talker) is non polarised
If anomalies or erratic readings are observed, swap the wires
NMEA output (to listener) is polarised

48. IS15 NMEA Interface Expander NMEA connections Dedicated input ports
Connect GPS/Plotter to TB5 (input) and TB6 (output)
Connect autopilot or other equipment to TB11 input and TB7 output
Output ports transmit same data
Each port should be limited to two listeners.
Please observe:
IS15 will not read water speed and temperature on NMEA when there is an Expander (or Transceiver) in the system

53. IS15 trouble shooting
Roblink test 1
Acess intallation menu ’General’ and then ’Roblink test’ (Combi only)
The numbers will count steadily up from 136 to 255
Flickering numbers indicates a problem with the specific data .
Counting down to 15 indicates data not present on Roblink

54. IS15 trouble shooting Message rate in times/sec.
Roblink test 2
Message rate in times/sec.
Slow message or flickering message rate may indicate erratic data
POS/NA1/NA2 may flicker because of low NMEA rate
Accumulates checksum errors - 5% is acceptable
Message rate = 5:
15 errors/min. is acceptable
Message rate=1:
3 errors/min. is acceptable

55. IS15 trouble shooting
Roblink test 3
Identifies the NMEA information that is received on the individual heads
If NMEA data is not transformed onto Roblink this may be checked on the Roblink Data Detect, Roblink test no. 1
A faulty head may cause the problem

56. IS15 trouble shooting
Speed indication does not go to zero reading when boat is not moving.
Old Transceiver with V1R2 software
Strong current (boat is moored)
Speed indication is reading zero all the time
Speed sensor not connected
Paddle wheel stuck or defective

57. IS15 Trouble shooting Cannot get NMEA data out from an instrument
Instrument has been set up/configured as listener
Enter NMEA setup menu and select ”NMEA communication: OUT”
Instrument is locked up and says ”Please wait”
Typical problem in stand-alone systems
Caused by high frequency ripple on 12V supply jamming the Roblink
Install a 100mF capacitor across 12V terminals
Install IS15 Power Supply
Always set ”Roblink OFF” if single NMEA repeater

58. IS15 Trouble shooting Erratic depth reading
Check that transducer surface is clean
Check Transceiver version (latest unit code is IA)
Older versions may give erratic readings, especially in shallow and muddy waters
Water ingress in transducer (check capacitance an resistance)
Check mounting location if problem at high speed and heavy sea
Water ingress and/or misty instrument
Check if old version with double glass (gluing problem)
Check mounting method (open back / angle)
