INTRODUCTION TO THE DS-RPC

BayTech’s DS-RPC provides a single dialup or EIA-232 gateway to
multiple EIA-232 devices. Used for accessing remote equipment or simply
switching between multiple ports, the DS-RPC provides a full duplex
connection between the host and up to 12 peripherals. In a typical
application, the host module connects to a local or remote computer, and
the peripheral port modules connect to devices such as routers, hubs,
servers, and Data Service Units (DSU’s). The DS-RPC is also compatible
with other BayTech products including the Remote Power Control (RPC)
unit.

1

DS-RPC OWNER’S MANUAL
INTRODUCTION TO THE DS-RPC
________________ _____________________________________________________ _____________________

In a typical application, the host port of the data switch is connected to a
local or remote computer and the peripheral ports are connected to devices
such as routers, hubs, bar code readers, terminals, etc. 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 consist s of two s lots for a hos t co mmu nicat ion s
module and a peripheral communication s m odule . The D S4-RPC base unit
consists of four slots for a host co mmu nicat ion s mo dule and u p to t hree
peripheral communications modu les. B oth c ontro l the four power outlets,
LEDs, non-volatile storage, and da ta flow between connected modules. The
data bus is an internal matrix of h ig h speed serial c hannels t hat al low s
independent and simultaneous trans mis sio n of data between modules.

The DS71 host communica tio ns modu le 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 sy stems
communications. The DS71-MD2 has a hig h speed EIA-232 port and an
internal modem for remote or local data acqu isiti on an d con trol. 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.

DS-RPC OWNER’S MANUAL
INSTALLATION
________________ _____________________________________________________ _____________________

PREPARING THE INSTALLATION SITE

The installation area should be clean and free of extreme temperatures and
humidity. Allow sufficient space behind the unit for cabling.

POWER

CAUTION:

This unit is intended for indoor use only. Do not
install near water or expose this unit to moisture. To prevent heat
buildup, do not coil the power cord when in use. Do not use
extension cords. Do not attempt to make any internal changes to
the power source. Do not attempt to modify any portion or
component of a DS-RPC unit unless specifically directed to; as in
Appendix E of this manual. BayTech must perform any internal
changes.

CAUTION:

High-voltage surges and spikes can damage this
equipment. To protect from such power surges and spikes, this
unit must have a good earth ground. A grounding screw connection
is located near the power switch on the back of the unit.

CAUTION

: Before removing or replacing any modules, turn off
main power switch located on the DS-RPC unit. Communication to
the DS-RPC will be disrupted while power is off.

CAUTION:

Before removing or replacing any cables or power
cords, turn off main power switch located on the DS-RPC.
Communication to the unit will be disrupted while power is off.

CAUTION:

Do not exceed the AC current rating for the selected
model. (See Appendix A “SPECIFICATIONS” for the DS-RPC).

CAUTION:

Although the power switch is turned OFF, the unit is
not totally isolated from the power supply. In order to be
absolutely removed from the power supply, the power cord must
be unplugged from the unit.

11

DS-RPC OWNER’S MANUAL
INSTALLATION
________________ _____________________________________________________ _____________________

CAUTION:

For PERMANENTLY CONNECTED
EQUIPMENT, a readily accessible disconnect device shall be
incorporated in the fixed wiring. For PLUGGABLE
EQUIPMENT, the socket-outlet shall be installed near the
equipment and easily accessible.

Applying power illuminates a green LED on the front panel of the DS­RPC. When the power switch is off, devices connected to the unit are not
receiving power.

POWER ON/OFF STATE

Each receptacle is individually controlled by an internal relay. Upon
initialization of power, the status of each receptacle will return to the state
it was in prior to losing power. For example, if Outlet 1 and Outlet 2 are
“ON” and power is removed from the DS-RPC, the status of Outlet 1 and
Outlet 2 will return to “ON” when power is restored to the DS-RPC.

POWER UP SEQUENCE

In order to minimize power surges, the DS-RPC sequences power to each
outlet in the “ON” state in 0.3-second intervals. When power is applied to
the DS-RPC, the initialization sequence requires a delay of 10 seconds
before power is available at the service receptacles. Following the 10­second delay, the DS-RPC sequences power to each outlet that is turned
“ON.” If you choose the option requesting the DS-RPC to reboot all
connected equipment, the DS-RPC sequences power to each outlet turned
“ON” in 0.1-second intervals.

CIRCUIT BREAKER

In the case of power overload, the circuit breaker automatically trips.
Determine the cause of the tripped circuit breaker, correct the problem
then reset the circuit breaker by depressing the circuit breaker switch.

RJ-45 CABLES AND ADAPTERS

IMPORTANT

The DS-RPC host communications modules have

:

an RJ-45 port which uses an 8-pin crossed modular cable to
connect to a local EIA-232 device such as a computer terminal or
external modem. Most serial computers do not have RJ-45
connections; therefore an adapter is provided with this unit to
convert from a DE-9 connector to an RJ-45 connector (Bay Tech
Part No. 9FRJ45PC-4). An adapter to convert from a DB-25
connector to an RJ-45 connector is also available from Bay Tech,
upon request (Bay Tech Part No. 25FRJ45PC-4). The 8-pin
crossed modular cable is configured to operate with these adapters.

CAUTION:

All power should be removed from the DS-RPC

prior to removing or installing cables.

Figures 1 and 2 provide visual representation of an RJ-45 receptacle and
plug; pin number assignments are given in Tables 2 and 3.

Fig. 1: RJ-45 Receptacle

Fig. 2: RJ-45 Plug

DS73TP CONNECTION

You should connect a straight cable between the RJ-45 ports of the DS73TP
module and the network hub. The “LINK” light will light green when a good
link has been established.

such as a computer terminal or external
modem. Most serial computers do not have
RJ-45 connections; therefore, an adapter is
provided with this unit to convert from a
DE-9 connector to an RJ-45 connector
(BayTech Part No. 9FRJ45PC-4). If you are
connecting to a modem, use a modem
adapter (BayTech Part No. 25MRJ45MD-6)
and an RJ08X007 8-pin crossed modular
cable.

BayTech also manufactures a
computer/terminal adapter (BayTech Part
No. 25FRJ45PC-4) for converting from a
DB-25 connector to an RJ-45 connector.

18

If you require a different adapter than the
one supplied with this unit, contact
BayTech’s Applications Engineers.

Using the 9FRJ45PC-4 adapter (or other
adapter) and the RJ08X007 crossed modular
cable, connect the serial port of your
computer to the RJ-45 port labeled EIA-232
on the DS71 or DS71-MD2 module.

DS-RPC OWNER’S MANUAL
DETAILED OPERATION AND CONFIGURATION
__________________________________________________________________________________________

Load serial port communications software.
Configure serial communications parameters
for the host terminal to match the DS71 or
DS71-MD2 module. The DS71 or DS71­MD2 modules have factory serial
communications parameters of 9600 bps, 8
data bits, 1 stop bit, no parity, XON/XOFF
disabled.

INTERNAL MODEM
CONNECTION
(DS71-MD2 ONLY)

IMPORTANT:

The DS71-MD2 modem option has priority over
the EIA-232 serial port. If a serial port user is in configuration
mode or connected to a DS74 I/O port when a modem connection
is established, the serial port user will be “booted” off allowing the
remote user to communicate with the DS unit.

NOTE:

Both “LINE” ports are active and either can be used.

The second “LINE” port is available for growth.

EXTERNAL MODEM
CONNECTION

The DS71-MD2 has a 14.4K bps internal
modem for remote access.

Using the RJ04X007 (RJ-11) modular cable,
connect either port labeled “LINE” on the
DS71-MD2 module to the telco wall jack.
Using communications software, dial the
modem using the ATDT command.

Using the 25MRJ45MD-6 adapter (or other

applicable adapter) and the RJ08X007

crossed cable, connect the COM (or serial)
port of the modem to the RJ-45 port labeled
EIA-232 on the DS71 or DS71-MD2
module. Using an RJ04X007 (RJ-11)
modular cable, connect the port labeled
“LINE” on the modem to the telco wall jack.
Using communications software package,
dial the modem.

DS-RPC OWNER’S MANUAL

__________________________________________________________________________________________

SELECTING A DEVICE

There are two methods of selecting a device,
menu driven selection and ASCII character
string method.

Menu Driven
Selection

From the main menu, select the number that

corresponds to the device you wish to

ASCII Character
String

operating the DS-RPC is the ASCII

access, followed by <cr>. To return to the
main menu, send the attention character five
times (;;;;;).

Another method of selecting devices and

character string method. To select a device
located on a peripheral module port, send
the port select code

(default is $BT),

the
module number, a comma, and then the port
number, followed by <cr> (there are no
spaces in the string). For example, to select
port 4 located on module 2, type BT2,4<cr>.
To select port 1 on module 9 (DS9 model),
type $BT9,1<cr>. To disconnect, type
$BT<cr>, then the attention character.

To configure a module, type $BT and the
module number followed by <cr>, then
$CONFIG followed by <cr>. This will allow
access to the configuration menu for that
module. Once configuration is complete,
type X for “Exit” followed by <cr>. To
access the main menu, type the attention
character five times.

NOTE:

You must exit main menu to send ASCII character string

commands.

NOTE:

While operating using the ASCII Character String method,

consider placing the DS-RPC in binary mode.

23

DS-RPC OWNER’S MANUAL
DETAILED OPERATION AND CONFIGURATION
__________________________________________________________________________________________

Binary Mode

If binary data containing the port select
code is sent to a module, the DS-RPC may
interpret the data as a command to change
ports. Binary mode prevents such an
occurrence by placing the DS-RPC in a
mode which does not look at the data. This
provides a reliable binary data transmission.
However, before a connection can be made
to another port, the binary mode must be
terminated.

Place the port in binary mode by sending the
port select code, a capital B, and a carriage
return

($BTB).

For example, if using the
default Port Select Code ($BT), place
Module 2, Port 1 in binary mode by typing

$BT2,1<cr>$BTB<cr>.

Terminate Binary

a BREAK condition command to terminate

Mode

From the terminal emulation software, send

binary mode. You may have to consult the
software users’ manual for the specific
BREAK condition command for the
emulation software you are using. For
example, the BREAK condition command
for PROCOMM PLUS

is “Alt B.”

RPC OPERATION

The RPC menu allows the user to monitor
and control the equipment attached to each
of the RPC four receptacles. From this
menu, you can turn on, turn off, or reboot
attached equipment, individually, or all
equipment, simultaneously.

The DS-RPC recognizes three basic
operating commands: ON n<cr>, OFF
n<cr>, and REBOOT n<cr>, where n
represents the outlet number and <cr>
represents a carriage return.

There are four red LEDs on the front of the
RPC unit. There is a corresponding red LED
for each of the RPC’s four receptacles. If
any or all of the LEDs are illuminated,
corresponding receptacle(s) are turned ON,"
and consequently, attached equipment is
receiving power. If any or all of the LEDs
are not illuminated, corresponding
receptacle(s) are turned “OFF.”
