dip-switches 1 and 2 must be positioned to ON. This option
must be selected before the installation of the module
5.6.1.2 Termination resistor
On the Ekip Com Modbus RTU module it is
possible to activate the terminating resis-
the corresponding dip-switches 1 and 2
(on the side of the module) must be posi-
tioned to ON. This option must be se-
lected before the installation of the mod-
ule. With the Ekip Com Modbus RTU
modules, the dip-switches 3 and 4 of the
Rpol (polarization resistance), are not
used.
