Multichannel controller
20.1.8 Example 7:
PC - connection to computer network
ATTENTION!
The data line must be locked at both sides with a
120 Ohm line resistance and must be supplied a
firm potential using the two link plugs on the two
jumpers on the circuit board of the display of all la-
test TOPAX versions.
For this reason, two link plugs have to be installed on
the display circuit board of the last TOPAX DX (see
chapter “4.9 First set-up and programming guide-
lines” on page 14).
On the sides of the PC; the load resistor has to be
plugged at the connector converter.
