Install the AutoBlock
This is an easy process but be careful to follow these steps to insure proper
function of the unit. The rear panel of your AutoBlock should continue to remain
accessible during this section.
2.3.1 Power Cord-The AutoBlock includes a 6’ power cord. Power requirements are
standard 115VAC 12amp US and Canada, 220VAC 6amp International. Plug the
power cord into the rear panel port labeled POWER IN, and plug into a standard
outlet. If the power line must be extended beyond 6’, the use of an extension cord
with the appropriate minimum electrical and safety standards may be used.
2.3.2 Remove the PDA from the box. Place it in the AutoBlock PDA cradle facing
forward, aligning the gold plated pins. The PDA cradle is mounted permanently
on the right side of the AutoBlock.
2.3.3 Attach the cord originating in the PDA cradle to the serial port labeled RS 232 on
the rear panel.
2.3.4 The PDA Power Cable is located in the HP Jornada PDA box. It has a 2-prong
plug and a black AC/DC adapter box. Plug this into the rear panel of the
AutoBlock in the receptacle labeled PDA.
2.3.5 There is a second cord in the PDA box. It is 4.5’ in length. One end of this cord
has 2 gold tabs; the other end is an “L” shaped plug. Attach this cord into the
pigtail coming from the RS 232 cable, and attach the “L” shaped plug into the
AC/DC adapter box. (Note: some of these cables may already be assembled by
the PDA manufacturer) When the PDA is place on the cradle a light should
illuminate on the top of the PDA. Red means the PDA is charging, Green is the
batteries are fully charged. If no light appears check all connections making sure
