V35BOB

NEW FOREST ELECTRONICS

Breakout box model V35BOB

Description

A comprehensive but easy to use tool for testing and troubleshooting V.35 interfaces. A bank of 34 switches allows any line to be opened or closed, the LEDs instantly show the state of the incoming signals, any line can be patched to any other using the jumper leads supplied.

(Technical note: V.35 is a specification for a communications interface that uses an M/34 connector, and a set of five balanced (differential) (V.35) signals for data and clocks, and nine unbalanced (V.28) signals for control lines)

Product

A fully featured, high speed (10 Mb/s) V.35 test tool
Monitors all 14 V.35 signals, tests voltage levels and ground potential difference
34 slide switches, to open or close any line
Self explanatory face plate design for ease of use
The six in-line LED monitors to the left of the switches show the signals from the DTE
The eight in-line LED monitors to the right of the switches show the signals from the DCE
Four state monitoring of signals: red = SPACE/ON, green = MARK/OFF, both = clock or data, neither = no signal
Patch any line to any other line, or force signal levels, using the jumper leads supplied
Monitor/trap facility
Ground potential difference test
Two cable adapters included, for connection to M/34 connectors
Battery powered (battery included), or can be used with an external 9V supply

V35BOB abbreviated specification & additional information

Number of breakout switches: 34
Number of probe points/sockets: 68 (identified by the labelled LED monitors next to each position)
Total number of monitors (2 LEDs each): 15 in-line (including G.P.D. pair), 3 unassigned
Six in-line LED monitors show the signals from the DTE - 2 balanced and 4 unbalanced (see table below)
Eight in-line LED monitors show the signals from the DCE - 3 balanced and 5 unbalanced (see table below)
(a) Differential (balanced) lines(V.35):- red = SPACE/ON (A-B > +0.3V), green = MARK/OFF (A-B < -0.3V), both = data or clock, neither = signal in transition region (-0.3V < A-B > +0.3V)
(b) Unbalanced lines (V.28):- red = ON (> +3V above signal ground), green = OFF (< -3V relative to signal ground), both = data or clock, neither = signal in transition region (-3V < Vs < +3V)
Suitable for operation to 10Mb/s, LEDs do not dim with increasing speed, the threshold remains at 300mV from DC to 10Mb/s
Two unassigned monitors/traps (for balanced and unbalanced) signal level and pulse detection, accessed by patching jumper leads from required lines (faster than 20nS)
Control signal simulation by patching from voltage source sockets above the switches
All 34 lines are wired through the unit
Interface connectors: One detachable male and one detachable female V.35 (ISO-2593) adapter cables
Power: Isolated 1.5 volt AAA cell (included) for balanced line LEDs, 9 volt battery (included) for general operation (life over 20 hours). May also be powered by an external 9 volt (stabilised, 100mA) mains adapter (not included)
Dimensions: (WxHxD) 105 x 150 x 20 mm (4.1 x 5.9 x 0.8 inches)
Weight: 295 g (10.4 oz)
Temperature: operating = 0 to + 50 deg.C (32 to 122 deg.F)
RoHS compliant, CE marked, made in EU
