CHAPTER 1 - OPERATION
The Patton 3080/V24 (CTS DSD-8) is a network enhancement accessory intended for high speed synchronous or asynchronous Modem, or port sharing applications. The 3080/V24 (CTS DSD-8) allows for immediate expansion of a system without the requirement of additional communication lines. The 3080/V24 (CTS DSD-8) allows any combination of up to eight DCE or DTE devices to share a single DCE or DTE high speed link in a point-to-point or multi-point polled network.
Channel Clocking
The Patton 3080/V24 (CTS DSD-8) is protocol transparent and operates in synchronous and asynchronous environments at data rates up to 76,800bps, depending on cable length and attached equipment. Clocking can be derived from the Master Port clock, (pins 15 or 24 for TXC and 17 for RXC), the internal clock generator or any Sub-Channel 1 through 6 (pins 15 or 24 for TXC and 17 for RXC).
Fallback Clocking
In the event of loss of an externally provided clock or optionally Sub-Channel 1 DCD becoming inactive, the 3080/V24 (CTS DSD-8) has the ability to automatically fall back to the predetermined internal baud rate clock or the Sub-Channel 6 RX Clock (pin 17).
Channel Interface
The 3080/V24 (CTS DSD-8) has nine DB-25 female connectors located on the rear of the unit. Each connector is pinned with EIA RS-232, using RS-423 electrical characteristics. This enables extended cable driving distances, which often bypasses the need for line drivers. Each port is DCE/DTE selectable, which eliminates the need for a crossover cable. DSR or DTR can additionally be forced to the active state individually on each Sub-Channel by Jumper control.

Anti-streaming
PATTON ELECTRONICS CO.
3080/V24
INSTALLATION AND OPERATIONS MANUAL
A typical problem often encountered is a
“STREAMING”
remote terminal. The streaming problem can tie up an entire circuit until the offending device has recovered or is powered down. A streaming condition occurs when a Sub-Channel remains active, disrupting the polling sequence. The 3080/V24 (CTS DSD-8) provides two user selectable modes of controlling a streaming condition, an automatic anti-streaming Abort Timer with eight selectable block lengths and a setting to disable anti-streaming for large data block transfers, and a manual Operator Control mode (front panel push button switch).
Automatic Anti-streaming
- Automatic Anti-streaming will block the asserted control signal from the Sub-Channel Port, releasing the 3080/V24 (CTS DSD-8) to accept requests from any other Sub-Channel that has not been locked out due to a streaming condition. When a Sub­Channel is locked out for streaming, a visual indication, by Sub-Channel, is provided on the front panel.
will still be broadcast to locked out Sub-Channels
Any data sent to the Master Port by the streaming device will be lost, but data
. Once a Sub-Channel is locked out due to streaming, the Sub-Channel will remain locked out until the attached device removes the streaming condition. When configured for “Switch on RTS” Mode, if RTS is held active, RTS must become inactive. When configured for “Switch on Data” Mode, if continuous data transitions have triggered the Anti-Stream logic, the transitions must stop before the DSD-8 will clear the Anti-Stream logic to that Sub-Channel. Removing the Sub-Channel via the front panel disable switch will not clear the Anti-stream logic for a Sub-Channel once it has been activated.
Manual Anti-Stream
- If manual Anti-Stream protection is chosen, a streaming condition caused by one of the attached terminals can be quickly corrected by the 3080/V24 (CTS DSD-8) via the associated front panel locking switches. A switch is provided for each Sub­Channel and permits the rapid removal of a streaming terminal without having to disconnect any cables or power down the offending terminal. Terminals may be selectively removed for self-test and maintenance without affecting the remaining Sub-Channels. Once the streaming condition has been corrected, the front panel switch is simply depressed to the locked (Enable) position (Green indicator ON) to re-establish normal operation. Removing a Sub­Channel with the front panel switch will block data from the Sub-Channel going to the Master Port but will not block data going from the Master Port to the Sub-Channel.
Channel Selection Modes
The 3080/V24 (CTS DSD-8) provides two selectable Sub-Channel service modes of operation, the Scanning Mode and Priority Mode. Depending on system requirements, either mode may be selected by internal DIP switch settings. Both modes switch on activity from the Sub-Channel.

3080/V24
124001UA
In the Scanning Mode the 3080/V24 (CTS DSD-8) scans each Sub-Channel, in sequence, beginning with Sub-Channel 1. This rotational sequence is repeated continually with each attached Sub-Channel having equal access to the communications link. When data or control lines from a Sub-Channel become active that Sub-Channel is switched through to the master port by the 3080/V24 (CTS DSD-8). All remaining Sub-Channels are locked out until the first device becomes inactive. When the Sub-Channel device becomes inactive, the 3080/V24 (CTS DSD-8) will resume scanning the Sub-Channels for another active signal.
When configured for Priority Mode operation, the 3080/V24 (CTS DSD-8) monitors all Sub­Channels simultaneously with Sub-Channel 1 having the highest priority. When a Sub-Channel becomes inactive, the 3080/V24 (CTS DSD-8) will automatically default to the highest priority (lowest number) Sub-Channel with activity.
Contention for the Master port is accomplished by asserting RTS (Request to Send) if the Sub-Port is configured as a DCE, DCD (Data Carrier Detect) if the Sub-Port is configured as a DTE or Data Transitions from the attached Sub-Channel devices in either configuration. The active interface lead RTS or DCD can be selected on an individual basis for each Sub­channel, selection of contention mode,
“Data Transitions”
or
“Interface Lead”
activation is selected in Sub-channel groups. Sub-channels 1 thru 4 are the first group and Sub-channels 5 thru 8 are the second group. All Sub-channels in a group will be set to the same contention mode, either
“Data Transitions”
or
“Interface Lead”
activation. Once a Sub-Channel asserts an active control signal, that control signal will be passed through to the Master Port, depending on DTE / DCE configuration of the Sub-Channel and Master Port. This control will be passed without delays. If the Master Port is configured as a DTE the signal will be passed as RTS. The CTS returned to the Master will have an optional delay added before the signal is returned to the Sub-Channel port.
Port Enable / Disable, front panel switches must be pushed in (GREEN indication) for a Sub­Channel to access the Master Port regardless of the mode of operation selected.
Channel Tail Circuits
A buffer is built into the unit for tail circuit (DCE to DCE) applications. An 8 bit centered ring buffer is used to correct the clock phasing errors generated between the Modem on the Master Port and the Sub-Channel port for the data transferred from the Sub-Channel to the Master Port. If the unit is operated in an asynchronous environment the buffer must be bypassed. This is accomplished by moving the SYNC/ASYNC switch to ASYNC.

Interface Connections
All connections are made via industry standard EIA RS-232 DB-25 female connectors located on the rear of the unit. The following interface leads are implemented, Chassis (1), TXD (2), RXD (3), RTS (4), CTS (5), DSR (6), Sig Gnd (7), DCD (8), Plus Unreg (9), Minus Unreg (10), TXC (15), RXC (17), DTR (20), XTXC (24). Pins 9 & 10 can be disabled by Jumpers on the PCB.
Front Panel LEDs
Front panel LEDs are provided to indicate power is applied, RXD and TXD activity from the Master Port, Sub-Channel activity of each individual Port, Anti-Stream condition of each Sub­Channel and an indication of clock fallback condition.
Channel Enable / Disable Switches
Front panel switches allow operator intervention to remove an individual Sub-Channel from accessing the Master Port. Positive latching type switches are provided for each Sub­Channel port for isolating or removing a streaming terminal. The Sub-Channel is activated by pushing the switch until it is in the “IN” position. The switch will indicate GREEN in color. To disable a Sub-Channel push the switch until it locks in the “OUT” position, the switch will indicate BLACK in color. Disabling a Sub-Channel with the front panel does not prevent the Sub-Channel from receiving data from the Master Port only from sending data to the Master Port.
Power Supply
A linear power supply is located internally, an external 110/220VA switch is located on the rear of the unit. If chassis ground and signal ground need to be tied together this can also be accomplished by switch selection. The unit is Rackmountable for 19" (or optional 23") cabinets, by using the included Rackmount Kit. Safety approvals granted are UL, CSA and TÜV. Emission approvals for FCC Class A and VFG243 have also been granted.

Tail Circuit Buffer (SW31-1)
(default ON)
The 3080/V24 (CTS DSD-8) has a Tail Circuit Buffer that is automatically selected when a Sub-Channel is set as a DTE. The buffer will provide clock synchronization of the data from the Sub-Channel to the Master Port for Tail Circuit operations. The buffer is de-activated when the Sub-Channel is configured as a DCE. When operating in an asynchronous environment the Buffer must be bypassed. To bypass the buffer in a synchronous or asynchronous application, set switch SW31-1 to OFF (ASYNC). For normal operation in a synchronous environment set SW31-1 to ON (SYNC). When using a tail circuit modem with the 3080/V24 (CTS DSD-8), the modem connected to the Sub-Channel, should be set to External Transmit Clocking. The modem at the remote end of the connection should be set to RX-TX Clocking or Slaved TX Clock. This will insure the same clock is present throughout the network and clock slippage will not occur.

Example:
If connecting a modem (DCE Device) to the PORT, then the port should be configured as a DTE interface. Slide both switches to the DTE position toward the interface connector. If connecting a terminal (DTE) to the Sub-Channel, the port should be configured as a DCE. Slide both switched to the DCE position away from the interface connector.

. When a port is selected as a DCE, pin 9 and 10 test
The port is always configured opposite to the
voltages are provided to the interface connector if JP4 and JP5 are installed. If the port is configured as a DTE, pins 9 and 10 are open. JP4 and JP5 control Plus Unreg and Minus Unreg to all Sub-Channels, therefore it is not possible to have test power on one DCE without having it on all DCE Sub-Channels.
Test Voltage Enable Pins 9 & 10 (JP4 & JP5)
Pin 9 and Pin 10 unregulated power is provided on each DB-25 connector configured as a DCE if JP4 and JP5 are installed. Pin 9 and 10 unregulated power is not provided to any connector configured as a DTE regardless of JP4 and JP5 installation.

DTR / DSR Forced Active (JP6 thru JP14)
DTR is tied to DSR on each of the Sub-Channel ports. If the device connected does not supply a DTR but requires DSR (DTE) or does not supply DSR but requires DTR (DCE), installing the forced DTR/DSR jumper (JP6-JP14) for the appropriate Sub-Channel will solve this problem. The line is forced to +6V via an 100 resistor, providing isolation to any driver that might be on the interface.

FACTORY Test Jumpers (JP1, JP2 and JP3)
The three factory test jumpers JP1, 2 and 3, must be installed for the unit to properly function. These jumpers are used in the manufacture and test of the product prior to shipment.
