INITIAL CHECK-OUT PROCEDURE
After the BIT 4886 card has been installed per PAR. 2.3, perform the following procedure to ver-
ify that it is functioning properly.
1. Connect the BOP-BIT 4886 Interface Card to either:
a) the GPIB bus using a standard GPIB cable connected to the BIT 4886 24-pin
GPIB connector (J1) or
b) to an external RS-232 controller with a DB9 type connector (male pins) by con-
necting the RJ45 patch cord supplied (see Table 2-1) to the BIT 4886 RS 232 port (J2), then
using the RJ45 to DB9 adapter supplied (see Table 2-1) to connect the RJ45 patch cord to
the external controller. On the RJ45 patch cord, the 6-pin connector plugs into the BIT 4886
RS 232 port, and the 8-pin connector plugs into the RJ45 to DB9 adapter (see Table 2-5 and
Figure 2-4).
2. Apply power to BOP power supply. The BOP-BIT 4886 will beep for less than 1 second, then
will be ready for use.
