5. CONNECTION OF INTERFACE UNIT
CS-120A
If the CSH-53 is combined with nav sensor (via Interface Unit CS-120A) and fishing equip-
ment, its function is expanded to include true motion presentation, echo sounder picture, FNZ
marker presentation, etc. This chapter provides the methods of interfacing the CSH-53 sonar
with other equipment and wiring details.
5.1 Connections for True Motion and Target Lock
Heading (digital) and speed (200 pulses/nm) data are required to provide the true motion and
target lock functions. Both data are fed to the display unit via Interface Unit CS-120A.
Basically, there are two methods to feed the data:
• Heading data is fed to J205 from A/D Converter AD-100 and the speed data to J206 from the
electromagnetic speed log.
• Both heading and speed data are fed to J207 from the CIF line of the CI-30/50/60.
Select one of the methods depending on the equipment installed. When both methods are avail-
able, it is recommended to connect both and select one by the DIP switch inside the CS-120A.

Note 1: AD-100 outputs two types of data. Do not use data for radars (25 ms interval).
Note 2: 200 pulses/mile ship’s speed data can be taken from a doppler sonar current indicator.
