4-2. REAR PANEL DESCRIPTION
4-2-1. The 3 pins pluggable terminal block, for connection of RS-485 interface:
When one set of DC power supply is remote controlled, through RS-
485 interface, a 1/4W 120Ω terminal resistor is
required. In general, a system that its connecting distance is less than 300m does not need to use the terminal
resistor. However, to avoid hav
ing interference, it is recommended to connect a 1/4W 120Ω terminal resistor
(connect to + and
– pin) at the last unit.
4-2-2. Digital programming Connector:
For GPIB remote control (Optional interface)
For LAN remote control (Standard interface)
