RS-232 to GPIB Interface
National Instruments GPIB-232-CT with Motorola CGDSEDN04X
RS232 serial null modem cable or equivalent; 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.
