4.4.2.1. Connections with intermodule synchronization.
Examples of connections with intermodule synchronization are shown on
Connections should be made with shortest twisted pairs for a number of E-502 modules located next
to each other.
The software of such a system should ensure the start of data collection of the master module
after the slave starts and pre-programmed these modules to the appropriate synchronization modes.
It is needed to programmatically turn on the pull-up resistors on the inputs START_IN and
CONV_IN to a low logic level on the last slave module in the circuit. It is recommended that no more
than 2 adjacent slaves are connected to the same chain with the master. Each slave in the circuit, for
example, E-502 #2, as it is shown on
synchronization circuit.
