Page 4: General Information
“Controlled by RTS”. Five pairs of bi-level LED indicators monitor TD, RD, RTS, CD, test and error. A single LED monitors power. The Model 1140ARC is designed to mount in Patton’s 2U high 19” rack chassis. This 16-card chassis has a switchable 120/240 volt power supply and mounts cards in a mid-plane architecture: The front “brains”... -
Page 5: Front Card Configuration
3.1 FRONT CARD CONFIGURATION The Model 1140ARC front card has two sets of eight switches (S1 & S2), which are mounted on the PC board (Figure 1, below). These configuration switches allow you to configure the Model 1140ARC for a wide range of applications. -

S1-5 S1-6 S1-7: Asynchronous/Synchronous Mode The setting for switch S1-7 determines whether the Model 1140ARC is in asynchronous or synchronous operating mode. S1-7 Setting Asynchronous Synchronous S1-8: Carrier Control Method The setting for switch S1-8 determines whether the carrier is “constantly on”...

S2-2 S2-3: Extended Signaling Rate The setting for switch S2-3 determines the range of variability the Model 1140ARC “looks for” in asynchronous data rates (i.e., the actual variance from a given frequency level the Model 1140ARC will tolerate). S2-3 Setting -2.5% to +1%... -

S2-4 and S2-5: RTS/CTS Delay The combined settings for switches S2-4 and S2-5 determine the amount of delay between the time the Model 1140ARC “sees” RTS and when it sends CTS. Options are no delay, 7 ms and 53 ms. - Page 10 3.2.1 HOW THE JUMPER WORKS Figure 4 (below) shows the 3-pin jumpers used on the rear card. The strap enables or disables a particular function depending upon whether it straddles pins 1 and 2, or pins 2 and 3. Figure 4. Orientation of interface card strap DTE Shield (Pin 1) &...

Page 11: Installation
This section describes the functions of the Model 1000R16 rack chassis, tells how to install front and rear Model 1140ARC cards into the chassis, and provides instructions for connecting the interface cables. 4.1 THE MODEL 1000R16 RACK CHASSIS The 1000R16 Rack Chassis (Figure 5, below) has sixteen short range modem card slots, plus its own power supply. - Page 12 4.2 INSTALLING THE MODEL 1140ARC INTO THE CHASSIS The Model 1140ARC is comprised of a front card and a rear card. The two cards meet inside the rack chassis and plug into each other via mating 50 pin card edge connectors. Use the following steps as a...
- Page 13 Figure 6. Model 1140ARC interface card options 4.3.1 RS-232 CONNECTION The RS-232 port on the rear card of the Model 1140ARC is wired as a DCE, and uses a female HD-26 connector. The HD-26 is an alternate connector according to the EIA RS-232E specification, and the pin-out is the same as a standard DB-25.

Page 14: Fiber Connections
4.3.2 FIBER CONNECTIONS The Model 1140ARC is designed to work with the self-powered Model 1140A, or with another Model 1140ARC. In either case, you will need one unit at each end of a dual fiber cable. This cable connects to the Model 1140ARC using either ST or SMA connectors. -
Page 15: Operation
The green “RTS” and “CD” indicators glow solid to show the control signal is on. The red “RTS” and “CD” indicators glow solid to show the control signal is off. When the 1140ARC is connected to a DTE, RTS will glow green for an incoming signal on RS-232 pin 4. -
Page 16: Test Modes
The Local Analog Loopback (LAL) test checks the operation of the local Model 1140ARC, and is performed separately on each unit. Any data sent to the local Model 1140ARC in this test mode will be echoed (returned) back to the user device. For example, characters typed on the keyboard of a terminal will appear on the terminal screen. -
Page 17: Remote Digital Loopback (Rdl)
Locate the lower of the two toggle switches on the front panel of the 1140ARC and move it to the right. This will activate the V.52 BER test mode and inject a “511” test pattern into the remote loop. - Page 18 The Model 1140ARC's V.52 BER test can be used independent of the V.54 loopback tests. This requires two operators: one to initiate and monitor the test at both the local and the remote Model 1140ARC. To use the V.52 BER test by itself, both operators should simultaneously...
