SRC-16 Plus Installation and Operation Manual
OVERVIEW
Product Overview
The Broadcast Tools® SRC-16 Plus is a computer interface to the real world.
Connected through an RS-232 or RS-422/485 serial port the SRC-16 Plus can noti-
fy your PC software program that any of 16 optically isolated inputs have been
opened or closed and allow your software to control any of the 16 SPDT, 1-amp
relays. Communication with the SRC-16 Plus can be accomplished via short “burst”
type ASCII or binary commands from your PC (computer mode.) Alternatively, the
SRC-16 Plus may be used in Data mode which allows the user to define custom
ACSII strings to control the relays as well as send custom ASCII strings when an
input is on. Two units may be operated in a standalone pair mode to form a "Relay
extension cord," with 16 channels of control in each direction. The unit can com-
municate using RS-232, RS-422 or RS-485 at data rates up to 38,400 baud. The
SRC-16 Plus may be expanded to 64 inputs x 64 outputs from a single serial port.
Optional external Ethernet and USB capabilities may be used.
