This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modifi­cation. If this product fails or does not perform as warranted, your sole recourse shall be repair or replacement as described above. Under no condition shall Patton Electronics be liable for any damages incurred by the use of this product. These damages include, but are not limited to, the following: lost profits, lost savings and incidental or consequen­tial damages arising from the use of or inability to use this product. Patton Electronics specifically disclaims all other warranties, expressed or implied, and the installation or use of this product shall be deemed an acceptance of these terms by the user.
1.1 RADIO AND TV INTERFERENCE
The Model 1205RC generates and uses 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 Model 1205RC has been tested and found to comply with the limits for a Class A computing device 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 Model 1205RC does cause interference to radio or television reception, which can be determined by turning the power off or removing the card, 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).In the event the user detects intermittent or continuous product malfunction due to nearby high power transmitting radio frequency equipment, the user is strongly advised to take the following steps: use only data cables with an exter­nal outer shield bonded to a metal or metalized connector; and, config­ure the rear card as shown in section 3.4 of this manual.
1.2 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 Union European (EU). A Certificate of Compliance is available by contacting Technical Support.

2.2 DESCRIPTION
The Patton Model 1205RC synchronous modem eliminator
rack card lets two synchronous hosts communicate with each other in
the same room for a fraction of the cost of a pair of high speed modems. Supporting synchronous data rates of 32, 48, 56, 64, 72, 112, 128 and 144 Kbps, the Model 1205RC can be configured to emu­late dial-up or leased line service. Maximum distance between the connected hosts is 300 feet. Timing can be set for internal or external clock, and all necessary data, clocking and control signals are support­ed.
The Model 1205RC is designed to mount in Patton’s 2U high, 16-
slot rack chassis, as well as Patton’s 2/4/8-slot desktop Cluster Boxes. This rack chassis and cluster boxes feature a switchable 120/240 VAC power supply (optional 48 VDC) and hot swappable function/interface cards mounted in a mid-plane architecture. Front panel LEDs show TD, DTR and CD activity for both ports, as well as power. The rear interface card has two UD-26 connectors for patching to the host devices.

3.3 FUNCTION CARD JUMPERS
The Model 1205RC has two ports (Port A and Port B), and each must be configured independently. Therefore, every function (such as clocking) has two
jumpers associated with it. As Figure 3 (below) shows, each jumper has three possible positions: strap covering posts 1 & 2, strap covering posts 2 & 3, or strap removed altogether. The detailed description for each jumper presents all valid strap positions.

JP2: Carrier Control (Port A)
The setting for jumper JP2 determines–with respect to Port A– whether the Model 1205RC’s carrier is “constantly on” or “controlled by RTS”.

JP3: Carrier Control (Port B)
The setting for jumper JP3 determines–with respect to Port B–
whether the Model 1205RC’s carrier is “constantly on” or “controlled by RTS”.

JP5: Clock Source (Port A)
The setting for jumper JP5 determines–with respect to Port A–
whether clocking is internal or external. Note: Only
Port A may be set
for external clock.

JP4: Clock Source (Port B)
The setting for jumper JP4 determines–with respect to Port B–
whether clocking is internal or receive loopback. Note
1
: If Port B is set
for receive loopback clock, Port A must
be set for external clock.
Note
2
: Port B may not be set for external clock.

4.0 INSTALLATION
This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 1205RC cards into the chassis, and provides diagrams for wiring the interface connections correctly.
4.1 THE MODEL 1000R16 RACK CHASSIS
The Model 1000R16 Rack Chassis (Figure 6) has sixteen card
slots, plus its own power supply. Measuring only 3.5” high, the Model 1000R16 is designed to occupy only 2U in a 19” rack. Sturdy front handles allow the Model 1000R16 to be extracted and transported con­veniently.
4.1.1 THE RACK POWER SUPPLY
The power supply included in the Model 1000R16 rack uses the
same mid-plane architecture as the modem cards. The front card of the power supply slides in from the front, and the rear card slides in from the rear. They plug into one another in the middle of the rack. The front card is then secured by thumb screws and the rear card by conventional metal screws.

WARNING! There are no user-serviceable parts in the
power supply section of the Model 1205RC. Voltage set­ting changes and fuse replacement should only be per­formed by qualified service personnel. Contact Patton Electronics Technical support at (301)975-1007, http://www.patton.com, or support@patton.com for more information.

4.3 HOST (DTE) CONNECTION
The Model 1205RC rear card has two UD-26 connectors, labeled “A1” and “B1” (see figure 7, below). These correspond to host (DTE) connection Port A and Port B, as discussed in Section 3.0.
To connect V.35 host (DTE) devices A and B to the Model 1205RC, follow these instructions:
1. Configure the Model 1205RC for your specific application accord-
ing to the instructions in Section 3.0 of this manual.
2. Connect host devices A and B to the Model 1205RC using multi-
pair adapter cables (see Appendix B for a list of custom adapter
cables available from Patton Electronics). Observe the following
conditions when making connections :
a) Each multipair cable must not exceed 150 feet in length
(see Figure 8, below).
b) If external clock is used, the host (DTE) device supplying the
clock must
be connected to Port A. The Model 1205RC
cannot
receive an external clock on Port B (see Section 3.0
for configuration details).
c) If receive clock is used on Port B, Port A must
supply an
external clock (see Section 3.0 for configuration details).
11
Notice! Any terminal cable connected to the Model
1205RC must be shielded cable, and the outer shield must be 360 degree bonded–at both ends–to a metal or metal­ized backshell.

5.2 POWER-UP
There is no power switch on the Model 1205RC: Power is auto­matically applied to the 1205RC when its card-edge connector makes contact with the chassis’ mid-plane socket, or when the chassis’ power supply is turned on. Note: The 1205RC is a “hot swappable” card—it
will not be damaged by plugging it in or removing it while the rack is powered up.
When the Model 1205RC is powered up, and both ports are pass­ing data normally, the following LED conditions will exist:
• PWR = green
• TD = blinking red and green
• CD = green
• DTR = green
