Bay Technical Associates DS2-RPC User Manual

Port selection is accomplished two different ways.

(1)  Use a simple menu-driven selection sequence or
(2)  send an ASCII character string to select a port.  The DS-RPC

also has four individual relay controlled, 115 VAC power
receptacles.  Each receptacle is controlled by sending simple
commands from a local or remote location.

The DS2-RPC base unit consists of  two slots for a  host communications
module and  a peripheral communications module. The DS4-RPC base unit
consists of  four slots for a  host communications module and up to three
peripheral communications modules.  Both control the four power outlets,
LEDs, non-volatile storage, and data flow between connected modules.  The
data bus is an internal matrix of high speed serial channels that allows
independent and simultaneous transmission of data between modules.

The DS71 host communications module is a system data controller that
directs operations between the base unit, system modules, and externally
connected devices.  The DS71 provides primary user access for systems
communications.  The DS71-MD2 has a high speed EIA-232 port and an
internal modem for remote or local data acquisition and control. The DS74
is a 4-port high speed EIA-232 peripheral communications module that
provides bi-directional communications between the host device and a
selected peripheral device connected to a DS74 port.  The DS74 has
selectable serial configuration for baud rate, word size, stop bits, parity,
DTR, RTS inactive state and XON/XOFF handshaking for each port.
