SRC-32 Installation and Operation Manual INTRODUCTION Thank you for your purchase of a Broadcast Tools® SRC-32, Serial Remote Control (referred to as the SRC-32 throughout this manual). We’re confident that this product will give you many years of dependable service. This manual is intended to give you all the information needed to install and operate the Broadcast Tools® SRC-32. SAFETY INFORMATION CAUTION! Broadcast Tools® Products, as with any electronic device, can fail without warning.
SRC-32 Installation and Operation Manual PRODUCT DESCRIPTION The Broadcast Tools® SRC-32 is a computer interface to the real world. Connected through an RS-232 or RS-422/485 serial port the SRC-32 can notify your PC software program that any of the 32 opto-isolated inputs has been opened or closed and allows your software to control 16 - SPDT, 1-amp relays and an additional 16 open collector outputs.
SRC-32 Installation and Operation Manual 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.
SRC-32 Installation and Operation Manual DIP 8 = (ON) Invert sense of LCD display of inputs. A closed contact will display as a “1” and an open as a “0”. (OFF) A closed contact will display as a “0” and an open as a “1”. NOTE: After changing DIP settings, be sure to press the reset button or recycle the power. SRC-32 ASCII Serial Burst Mode Commands: The burst mode allows a computer or ASCII terminal to control and interrogate the unit. This section defines all burst mode commands.
SRC-32 Installation and Operation Manual Output Control Commands: *uORrrL*uORrrF*uORrrPtt- Latch Output rr, (output number 01-32). 01–08 are relays, 09–32 open collectors Unlatch Output rr, (output number 01-32). 01–08 are relays, 09–32 open collectors Pulse Output rr, (output number 01-32). Pulse Length tt: 0099 corresponds to 00 - 9.9 Seconds. 01–08 are relays, 09–32 open collectors ASCII Information Retrieval Commands: *POLL - Respond with unit (ID) address in appropriate time slot.
SRC-32 Installation and Operation Manual Pair Mode The SRC-32 can be used to transmit the outputs from one unit to another over a serial connection. The logical sense of the inputs is inverted when written to the outputs of its corresponding unit. Normally inputs are high and when closed go to a logic 0 when in pair mode. When logic 0 is received, it will write logic 1 to the output. This allows the relays connected to outputs 1-8 to come on if its corresponding input is closed.
