1.2.8 V.35 Personality Module (1251)
When using the two-port HSU 530/35, HSU-AD 530/35, and four-port HSU 530/35 Cards,
you may want to connect the RS-530 output jack to RS-232 external equipment (for all of
these cards). The V.35 Personality Module is a adapter module that plugs into the female
DB-25 port and connectors, then attaches via a male/female connector to the external CPE
device. Figure 1-6 shows this module.
Note: The CPE connection cables should be less than 25 feet long. For RS232 operation,
the recommended maximum cable length is less than 25 feet, and the speed should not
exceed 56 kbps.

The three HSU 530/35 Cards also have internal switch settings for changing signals from
RS-530 to V.35 format, as previously described. You must also set those switches for RS-530
interfacing when attaching personality modules to the associated card jacks.
1.2.9 RS-232-E Personality Module Description (1253)
The RS-232-E Personality Module converts 530-A signals to RS-232-E format which allows
the HSU Cards to interoperate with equipment employing an interface conforming to the
ANSI/EIA/TIA-232-E electrical characteristics. Figure 1-7 shows this module.
