 ISACC Instruction Manual

To communicate locally using your PC, you must first hook up and configure ISACC’s RS232
port with your PC’s RS232 port.  ISACC’s RS232 port is positioned on the circuit board at
location P4 next to the phone jack and is labelled RS232 PORT (DCE).  Provided with
ISACC is a Communication Hookup Kit that contains the following:

•  Male DB25 plug to RJ11C
•  Female DB25 socket to RJ11C
•  Female 9-pin socket to RJ11C
•  10 feet of RS232 wire with male RJ11C on each end

To connect your PC to ISACC’s RS232 port, do the following:

  Insert the male DB25 plug into ISACC’s RS232 port

  Insert one end of the RS232 wire into the male DB25 plug

  Insert the other end of the RS232 wire into the female DB25 socket

  Insert the female DB25 socket into your PC’s male RS232 port.  Make sure that you are

connecting to one of the PC’s COM ports and not to a parallel port.  If your PC’s COM port
is a 9 pin connector, then use the included 9-pin socket instead.

See page 30 for ISACC’s RS232 Specifications and a diagram of the RS232 DB25 socket.

  After connecting the PC with ISACC, you may need to configure the PC's RS232 port to

communicate at the same speed (bps) as ISACC (see  the ISACC Manager User's Manual).  If
this is not an option, you can change ISACC's communication rate by configuring the shunts
at location P10 on the ISACC board.  Before changing anything, read the following:

IMPORTANT:  The speed of ISACC’s RS232 port is completely independent of
ISACC’s built-in modem or modem speed.  ISACC’s modem has its own separate
RS232 port built in.  Therefore, you do not need to configure ISACC to communi-
cate at the same speed as its built-in modem (1200 bps) when you are communi-
cating locally.  Use the rate at which your PC can communicate.

ISACC is factory configured at 9600 bps, which is the fastest it can communicate.  All PCs can
communicate at least that fast.  Unless your PC definitely communicates at a slower speed, do
not

 change the configuration of the shunts for local communication.

ISACC is capable of communicating locally at the following speeds:

  150 bps

2400 bps

  300 bps

4800 bps

1200 bps

9600 bps

There are 9 pins at board location P10.  (P10 is located under the acrylic safety panel next to
the digital outputs terminal block.) Three shunts are provided to configure the communication
speed for the RS232 port.  The speed is determined by the different positions of the shunts.
All three shunts must be used for ISACC to communicate properly.  To configure the shunts,
you must first remove the acrylic panel.  Using needlenose pliers, move the shunts to the
