Reserved except if X=C : Pulse C: IN TTL
(*) ROVINS, V1, V2 power GND are insulated and insulated from RS GND
(**) Serial GND and Pulse GND are common for a given port (i.e., GND_A for port A,
GND_R for repeater port).
(***) The external trigger lines are insulated. They can be used for example to trigger
acoustic emission of a DVL connected to the ROVINS.
(****) Pulse C only on Port C, Pin 11 common for Pulse and Port C
The Port X connector provides the following inputs and outputs:
•
1 user-configurable digital input (RX). Pin assignment in RS232 or RS422 electrical
levels is detailed in Table 3
•
for wiring. RS232 input signal should provide a voltage min ± 5 V to ± 20 V when
loaded.
•
1 user-configurable digital outputs (TX). Pin assignment in RS232 or RS422 electrical
levels is detailed in Table 3
•
for wiring. RS232 output signal level is ± 5 V min when load is 3 k
Ω
.
•
1 pulse input. This pulse is only available on the Port C.
•
1 ext pulse coming from the central connector
•
2 different power supply (EXT1 and EXT2) for powering external sensor
R S232/RS422 ports have to be wired with twisted shielded pairs. Refer to section V.6
for shielding recommendations.
