SRC-32 Installation and Operation Manual
INSTALLATION
INSTALLATION GUIDELINES
DIP Switch Settings:
Multiple SRC-32’s can be “daisy chained” together using a single serial port to a PC
and the 10 pin IDC “EXT” headers marked “EXT-1” and “EXT-2”. The EXT-2 from
one SRC-32 can be connected to the EXT-1 of the next and so on. Each board
should have a unique address set on its DIPswitch address setting. Up to three addi-
tional, SRC-32’s may be connected together so that up to 128 inputs can be moni-
tored and 128 outputs controlled from one PC’s com port, other serial devices or the
external Ethernet option. The SRC-32 connected to the PC is considered the
“Master” unit and must have its address at zero and jumper JP13 set to RS-232 or
RS-422/485 depending on the PC connection. Each external SRC-32 should have a
non-zero address of 1,2 or 3. The external “Slave” SRC-32 needs to have JP13 set
to “External”. NOTE: After changing Dipswitches, be sure to press the reset switch
or recycle the power.
DIP 1, 2
The board address is set using Dipswitch numbers 1 and 2 in normal hex format:
1, 2
0 0
=
0 (master) No polling is required for status.
0 1
=
1
1 0
=
2
1 1
=
3
DIP 3, 4
= Set baud rate
3, 4
0 0
=
9600
0 1
=
2400
1 0
=
19200
1 1
=
38400
Baud rate will be set by the DIPswitches on power up or reset. It can also be
changed using the serial port commands at other times, but if the SRC-32 is reset,
the baud rate will be set according to the DIP settings.
DIP 5 = (ON)
Hex mode – When on, hex “Burst” mode is selected. Refer to the
protocol below for hex commands.
(Off)
is ASCII mode. Refer to the ASCII proto-
col below for ASCII commands.
DIP 6 = (ON)
Pair mode, inputs from one SRC-32 will map directly to outputs of
another SRC-32 when connected together via RS-232 or RS422.
(OFF)
normal
operation via RS-232/422. DIP 5 must also be ON, as pair mode only works in hex
mode.
DIP 7 = (ON)
Modem mode. (Not yet implemented) Set master to address 00 and
slave to 01. Master will output an AT command to an external modem and call the
slave. Also set DIP 5 and 6 ON for hex pair mode.
NOTE:
After changing a
DIPswitch setting, the
board must be reset by
pressing the “RST”
button or by cycling the
power.
