1) A terminating resistor connected to the display link is intended to
shape the waveform on the display link (RS485). When a display link
is short or used in a noisefree environment, it may be able to operate
normally even if no terminating resistor is connected to it. However,
a terminating resistor must always be factoryconnected to the display
link, because otherwise qualitative evaluation is impossible. If a
terminating resistor is not connected to a display link, it may be
impossible to update the screen and use the keyboard.
2) A terminating resistor must be connected to both ends of the display
link. The CRT/MDI has a builtin terminating resistor. If the
CRT/MDI and Power Mate are connected on a onetoone basis, a
terminating resistor is connected using the cable (Section 8.1.2). If
there are n Power Mates in one display link, connect a CRT link
terminating unit to the display link adaptor to terminate the link.
3) The display link connector JD41 accommodates coaxial sync interface
function signals (RS485). The display link adapter connects a
terminating resistor to both types of signals. If the coaxial sync
interface function is not used, it is unnecessary to connect a
terminating resistor to the coaxial sync interface function signals.
