Instructions for installing ACW Handheld Extender Kit
Note: In order to use the ACW handheld Extender kit
there must be an available AC outlet in the
ACW unit, 2 available AC outlets in the equipment room, and 2 pair 24 AWG twisted pair phone
cable run between the ACW and the equipment room.
1. Turn off the power to the ACW at the breaker. The red switch will NOT shut off power
to the AC outlet used in the extender kit.
2. Connect the 25 Pin to 9 Pin Cable to one of the RS232/422 Converters. This assembly
will go into the ACW cabinet.
3. Plug the 9 Pin connector of the assembly in step1 to the handheld port.
4. Attach the assembly from step 2 onto the hopper base plate using one of the supplied
Hook and Loop Tape strips.
5. Connect one of the twisted pairs in the phone wires to the terminals labeled TD (A) and
TD (B) of the converter in the ACW. Connected the other twisted pair to the terminals
labeled RD (A) and RD (B) of the converter in the ACW. In the table below, make a note
of which color goes to which of the terminals.

TD (A)
TD (B)
RD (A)
RD (B)
5. Find the positive wire of one of the 12 V wall adapters. The positive wire is the one that
has the white lettering on it. Attach this wire to the terminal on the converter l12
VDC. Attach the other wire of the wall adapter to the terminal labeled GND.
6. Connect the twisted pair wires to the second converter. First connect the Transmit wires
[TD (A) and TD (B)] from the first converter to the Receive terminals [RD (A) and RD
(B)] of the second converter. Next connect Receive terminals [RD (A) and RD (B)] from
the first converter to the Transmit wires [TD (A) and TD (B)] of the second converter.
This is illustrated in the diagram below.
