WARRANTY NOTICE  
WARRANTIES: Patton Electronics Co. (hereafter referred to as Patton) warrants that its equipment is  
free from any defects in materials and workmanship. The warranty period shall be two years from the  
date of shipment of equipment. Patton’s sole obligation under its warranty is limited to the repair or  
replacement of the defective equipment, provided it is returned to Patton, transportation prepaid, within  
a reasonable period. This warranty will not extend to equipment subjected to accident, misuse,  
alterations or repair not made by Patton or authorized by Patton in writing.  
PUBLICATION NOTICE  
This manual has been compiled and checked for accuracy. The information in this manual does not  
constitute a warranty of performance. Patton reserves the right to revise this publication and make  
changes from time to time in the content thereof. Patton assumes no liability for losses incurred as a  
result of out-of-date or incorrect information contained in this manual.  
RADIO AND TV INTERFERENCE  
The Patton MSDs generate and use radio frequency energy, and if not installed and used properly—that  
is, in strict accordance with the manufacturer’s instructions—may cause interference to radio and  
television reception. The Patton MSDs have been tested and found to comply with the limits for Class A  
computing devices in accordance with the specifications in Subpart J of Part 15 of FCC rules, which are  
designed to provide reasonable protection from such interference in a commercial installation.  
However, there is no guarantee that interference will not occur in a particular installation. If the Patton  
MSDs do cause interference to radio or television reception, which can be determined by disconnecting  
the cables, the user is encouraged to try to correct the interference by one or more of the following  
measures: moving the computing equipment away from the receiver, re-orienting the receiving antenna,  
and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment  
and receiver are on different branches).  
CE NOTICE  
The CE symbol on your Patton Electronics equipment indicates that it is in compliance with the  
electromagnetic Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the European  
Union (EU). A Certificate of Compliance is available by contacting Technical Support.  
SERVICE  
All warranty and non-warranty repairs must be returned freight prepaid and insured to Patton Electron-  
ics. All returns must have a Return Materials Authorization number on the outside of the shipping  
container. This number may be obtained from Patton Electronics Technical Support at:  
tel: (301) 975-1007;  
NOTE: Packages received without an RMA number will not be accepted.  
Patton Electronics’ technical staff is also available to answer any questions that might arise concerning  
the installation or use of your Patton MSDs. Technical Support hours: 8AM to 5PM EST, Monday  
through Friday.

CHAPTER 1 - Operation  
The Patton 2020P (IC-V.24/V.35) is a RS-232 to V.35 interface con-  
verter. The interface converter operates bi-directionally. DCE / DTE  
selection of the ports permits interfacing RS-232 terminals to V.35  
Modems or RS-232 Modems to V.35 terminals. This adapter is ideal for  
High Speed Group Band Modems since it can operate at 56Kbps or  
faster (Up to 128Kbps).  
Because the operator can configure the interface converter to be RS-232  
on the terminal port and V.35 on the Modem Port, or V.35 on the terminal  
port and RS-232 on the Modem Port, the 2020P (IC-V.24/V.35) can  
satisfy either interface conversion requirement. Devices can be sepa-  
rated up to 600 feet away from the 2020P (IC-V.24/V.35) on the V.35  
side and RS-232 devices can be extended up to 50 feet away. The unit  
is supplied with a female DB-25 connector on the RS-232 port and a  
female 34 pin connector on the CCITT V.35 port.  
The Patton 2020P (IC-V.24/V.35) is housed in a sturdy aluminum enclo-  
sure and has an internal 110/220VAC switch selectable power supply.  
The Interface Converter will also fit into the 1010R16/P/UI (MCS-16C)  
card rack assembly, providing a convienent means to us the cards in a  
data center.  
The unit has MET, c-MET and CE approvals and can operate on stan-  
dard power found in most countries.

CHAPTER 2 - SETUP AND INSTALLATION  
Installation  
Set switches to match the required configurations based on the diagrams  
below. The cabling between each device and the 2020P (IC-V.24/V.35)  
must be terminated with male connectors. J1 is the RS-232 / V.24  
interface and J2 is the V.35 interface. The IEC connector is provided to  
interface to the power plug required in the country of use. Insure the  
110/220VAC switch is set correctly for the line voltage in use prior to  
appling power to the 2020P (IC-V.24/V.35).  
Selection of DTE/DCE  
To connect an RS-232 terminal type device (DTE) to a V.35 Modem type  
device (DCE), connect the terminal to J1 and the Modem to J2. Move  
SW1 and SW2, to the DCE position, TOWARD THE REAR OF THE  
UNIT.

Equipment Grounding  
JP4 provides grounding interconnection in those systems requiring a  
connection between Pin # 1 (Frame Ground) and Pin # 7 (Signal  
Ground). If signal ground and chassis ground interconnection is desired  
install the jumper on JP4.  
LED Indicators  
The Following LED indicators are provided for diagnostics: Power,  
Transmit Data (TD), Receive Data (RD), Request to Send (RTS), Clear  
To Send (CTS) and Carrier Detect (DCD).  
Factory Test Straps  
The Factory Test Straps JP1, JP2 and JP3 must be installed for proper  
operation of the 2020P (IC-V.24/V.35).
