SRC-8 III Installation and Operation Manual INTRODUCTION Thank you for your purchase of a Broadcast Tools® SRC-8 III, Serial Remote Control (referred to as the SRC-8 III 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-8 III. SAFETY INFORMATION CAUTION! Broadcast Tools® Products, as with any electronic device, can fail without warning.
SRC-8 III Installation and Operation Manual PRODUCT DESCRIPTION The Broadcast Tools® SRC-8 III is a computer interface to the real world. With connection through an RS-232, RS-422 or RS-485 serial port, the SRC-8 III can notify your PC software program that any of 8 optically isolated inputs has been opened or closed and allows your software to control eight SPDT, 1-amp relays. Communication with the SRC-8 III can be accomplished via short “burst” type ASCII or binary commands from your PC (computer mode).

SRC-8 III Installation and Operation Manual 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 protocol below for ASCII commands. DIP 6 = (ON) Pair mode, inputs from one SRC-8 III will map directly to outputs of another SRC-8 III when connected together via RS-232 or RS-422. (OFF) normal operation via RS-232/422. DIP 5 must also be ON as pair mode only works in hex mode.
SRC-8 III Installation and Operation Manual Connecting Multiple SRC-8’s: Multiple SRC-8 III’s can be “daisy chained” together using a single serial port. Units are daisy-chained using the 10 pin IDC “EXT” headers marked “EXT-J12” and “EXT-J14”. Connect one end of the supplied ribbon cable to the “EXT-12” header on the first SRC-8 III and the other end of the ribbon cable to the “EXT-14” header of the next unit and so on. Each board should have a unique address set on its dipswitch address setting.
SRC-8 III Installation and Operation Manual Information Retrieval Commands *POLL - Respond with unit (ID) address in appropriate time slot. If there are multiple units on the line, each will respond with a different delay after receipt of this command. *uSPii - Send status of input ii. Response is SuP,ii,x where x is 0 if the corresponding input is high, 1 otherwise. *uSPA - Send status of all inputs. Response is SuP,A,x,x,x,x,x,x,x,x where input 1 is first and input 8 is last.
