RS–232 to GPIB Interface
• National Instruments GPIB–232CT–A is used to interface the LMF to the test equipment.
• Standard RS–232 cable can be used with the following modifications (see Figure 1 -1 )
This solution passes only the 3 minimum electrical connections between the LMF
and the General Purpose Information Bus (GPIB) interface. The control signals are
jumpered as enabled on both ends of the RS–232 cable (9–pin D). TX and RX signals
are crossed as Null Modem effect. Pin 5 is the ground reference.
Short pins 7 and 8 together , and short pins 1, 4, and 6 together on each connector .
