9.5 Setting The Communications Link Termination Jumper

The last unit in the communications link must be terminated and all other slave units in the link must be
unterminated, or data transfer will not function properly.
Units are shipped from the factory with terminations set for unterminated operation.
To terminate an instrument, jumpers W2 and W3 on card #046925 in Slot 1 must be both set in the 1-2
position. To remain unterminated, jumper W2 and W3 must be in the 2-3 position. See Figure 9-6.
To gain access to the circuit card, follow instructions in Section 9.1.
For serial communication wiring, see Communications Wiring in Section 2.5.
