1 DESCRIPTION
The 6PTM2 Peripheral Transfer Module is a small electronic device intended to interface the
transmit (XDN), receive (RDN), and request-to-send (RTS) signal lines from two RS-232
serial ports (input/output portsA and B) to a single RS-232 input/output serial port.
1.1 PHYSICAL DESCRIPTION
The 6PTM2 can be housed in a small plastic case and supplied with an external power pack
for stand-alone use, or it can be part of a Peripheral Transfer Panel (PTP)Assembly.
The PTP assembly provides up to sixteen PT Modules in the fully equipped configuration. If
initially configured with less than 16 modules, the PTP Assembly can be expanded at a later
date.
1.2 OPERATIONAL DESCRIPTION
The RDN signal is passed from the Common port to ports A and/or B. The XDN signal is
passed from ports A and/or B to the Common port. The RTS signal can be passed from ports
A and/or B to the Common port, or it can be locally generated from the XDN signal.
A three-position switch allows the 6PTM2 to automatically switch (center position) to the
active port, or force it to maintain connection with the A or B port.
The RTS output signal from the common port is normally supplied as an RS-232 voltage level
which can be used to turn on the carrier on a modem. As an option, a set of dry contacts can
be supplied which can be used to activate the Push-to-Talk (PTT) input on a radio.
When the RTS signal is locally generated, it is triggered by the first bit of the message being
transmitted, and its time duration is adjustable. The transmitted message must begin with
one or more extra bits (garbage bits, or byte), followed by a delay time (no data) equal to the
RTS delay required by the modem or radio system being controlled, followed by the actual
data.

2  JUMPERS AND ADJUSTMENTS: Copyright © 2016 QEI
2 JUMPERS AND ADJUSTMENTS:
The 6PTM2 module has one jumper and two adjustments that are used to enable and adjust
the internally generated RTS (or PTT), as follows:
Jumper E1 Out = RTS controlled by the A or B port’s RTS input signal.
Jumper E1 In = RTS controlled by the data being transmitted (XDN)
R4 potentiometer Used to adjust the locally generated RTS duration time,
up to 1000 msecs., from the start of the first bit if the
message being transmitted.
R2 potentiometer Used to adjust the RTS turn off delay time, measured
from the end of the last bit of the transmitted message.

serial ports of two redundant terminal servers (DECServers) in a TDMS-2000 Master Station
System.
8 EXPANDING AN EXISTING PTP ASSEMBLY
This section outlines the steps necessary to expand an existing Peripheral Transfer Panel
(PTP) Assembly.
There are three basic steps that need to be accomplished when expanding an existing PTP
Assembly.
1. Using the hardware provided in the PTP expansion kit, mount the Peripheral Transfer
Module(s).
2. Install the Peripheral Transfer Panel Extender Cable Assembly by:
Removing the 12VDC power plug (male) on the last existing PT Module and reconnect it
to the female connector on the expander cable.
Insert the 12VDC power plugs of the expander cable in to the last existing PT Module and
all the newly added PT Modules.
3. Make the required RS232 port connections via the RJ-45 jacks to their associated
peripheral devices.
