The Worlds best Break Out Boxes
since 1985
|
|
Bob 100 Compact Break Out
Box
A compact, industrial
strength, BREAK OUT BOX used to monitor and
redirect RS-232-C circuits.
- 102 high efficiency LEDs.
- Breaks and redirects all 25 lines.
- Four-state monitors on all lines on both
DTE/DCE.
- Two DB9/25 pole adapters plus conversion
table.
- Full cable test function and GPD test.
- Bi-directional Current Loop test (4,10,20,60
mA).
- Jumper cable set and 12 inch ribbon cable.
- Easy operation, lightweight and compact.
Connectors
One female and one
male 25 pin Sub-D connector
Signal Status Display
Mark, Space,
Clocking, None indication on all 25 pins
on both sides of the breakout switches.
Access Sockets
Sockets are located
on both sides of the breakout switches
allowing direct access to both
interfaces.
Jumper Cables / Patching
A sturdy set of
jumper cables with high quality gold
plated plugs is provided to allow cross
patches of interface lines. Included are
six two-pin jumpers plus two four-pin
jumpers.
Ground Potential Differences Test Circuit
The different ground
potentials of the two interfaced devices
can cause problems with signal
interpretation. The Circuit testing this
difference makes use of G. P. D. monitor
connected to the left side of switch #7.
Power/Test Voltage Sources
The basic function of
the BOB100 do not require battery power.
The tester can use one 9 volt battery
for the purpose of generating + or +
voltage for testing.
Physical (Hand Sized)
7.4 x 3.4 x .7
inches, 8.9 ounces.
Current Loop Test Circuit
The Current loop test
circuit can be used to measure 4, 10,
20, and 60 mA circuits. The LED
illuminates at 80% of the stated
current. Maximum current is 3 times
stated with an upper limit of 80 mA.
Packaging
The BOB100 is
supplied with a small leatherette case,
jumpers, manual, battery connector, and
11 inch cable.

RS232 Digital Line Voltage
Monitor
- Four-state
monitoring of all lines
- 24
green and 24 red high bright LEDs
- Two
DB25/9 mini adapters included
- DB25
and DB9 described on faceplate
- Loop-back
function to test cables
- Compact/
rigid design
- User
manual, pouch for carrying
This compact
tool shows the state of all lines in a
glance. It connects to, can convert
between, DB25 and DB9 interfaces. The face
plate gives a complete description of all
signals with their pin numbers and
explains the DB25/9 conversion. It is
constructed by field service engineers and
famous for its convenience in use and
reliability.
The Comtest RS232LM
offers features not available on other
testers of its kind. The DB25/9 pole
adapters make it not only to test DB25 and
DB9 pole communication but can also
convert between them. The logical face
plate provides complete and easy to read
information.
It is interface
powered. The high bright LEDs show signal
strength, the load per line is typically
1mA with a 6.6volt signal. The LEDs are
mounted behind a structured panel, they do
not glance and give distinct light in
contrast with the black face plate.
In addition to
monitoring line activity it can it can be
used as loop-back unit to test ready
installed cables using signal ground as
return wire.
