CONNECTOR PINOUTS
7.4 Standard Cables
Ballard sells a number of different cables that are useful for wiring to OmniBus II
products. Each cable has a standard length. Non-standard lengths may be speci-
fied by adding a /xx suffix after the part number, where xx is the length in feet.
For example, a 16036/10 is a ten-foot-long 16036.
7.4.1 PN 16035 Cable Assembly: LFH to LFH
This is a three-foot-long straight-through cable with 60-pin male LFH plugs on
both ends. It is wired pin for pin and pair for pair as shown in Table 7.1. The
16035 is useful for connecting an OmniBus II product to a user-provided panel or
other assembly.
7.4.2 PN 16036 Cable Assembly: LFH to Two 25-pin D-subs
This is a three-foot-long Y-cable that adapts a 60-pin male LFH plug (labeled
P1) to two 25-pin male D-subminiature connectors (P2 and P3). Because of the
size and popularity of D-sub connectors, some users may find it easier to inter-
face to them than to the OmniBus II LFH connectors. As can be seen from
Table 7.1, there is symmetry between the upper and lower halves of the LFH
connector. On the 16036 cable assembly, the upper half of the LFH connector
is wired to one D-sub and the lower half is wired to the other D-sub, thus giv-
ing similar signals on the corresponding pins of both D-subs. The wire pairs on
the 16036 are different from those on the 16035. Wiring for the 16036 cable is
shown in Table 7.6 below.
