3.4.16 Optoisolated external reset input
Module’s optoisolated digital input is routed to a separate connector, designed for the
connection of remote (external) RESET devices and ensures galvanic isolation (optoisolation
with breakdown voltage of 500 V) when connecting relevant devices to the module.
In terms of its design, the optoisolated digital input represents Isolated Reset (XP23) two-pin
connector with a pitch of 2 mm.

A fragment of a schematic diagram for implementation of module’s digital input optical isolation
is shown in the Figure 3-22 below:

When manufacturing the cable, it is recommended to use PHR-2 socket (JST) for crimping the
wire with SPH-002T-P0.5S (JST) contacts, or ACS00031-03 accessory (see Table 1-3).
3.4.17 System reset connector
CMOS Reset (XP12) two-pin connector is designed for button connection, not fixing it in a
pressed condition. Pressing the button leads to system reset of the module and restart of the
system.
