2.8 Jumper Setting
The J1~J4 is used to set the signal type of the pulse output signals (DIR
and OUT). The output signal type could be differential line driver output
or open collector output. Please refer to section 3.1 for details of the
jumper setting. The default setting is the differential line driver mode.
2.9 Switch Setting
The switch bits 1/2 of S1 are used to set the EL limit switch’s type. The
default setting of EL switch type is “normal open” type limit switch (or “A”
contact type). The switch on is to use the “normal closed” type limit
switch (or “B” contact type). The default setting is set as normal open type.
The bits 3/4 of S1 are used to set the active logic of CMP1,CMP2
respectively.
Default setting is active low. This means that when a positive comparison
condition is met ,CMP will go high for 100 us automatically.
