Data Line Monitor model
RS530LM |
|
A simple to use tool for testing
and troubleshooting RS-530 interfaces, the LEDs instantly show the state of all
signals.
(Technical note: RS-530 (EIA-530)
is a specification for a communications interface that uses a DB-25 connector
and V.11 (RS-422) differential equivalents of the main V.24 (RS-232) signals. In
addition three link management control signals are implemented using V.10
(RS-423) single ended interfaces, and separate V.11 (RS-422) differential clock
lines are used as part of receiving and transmitting data).

- A complete RS-530 line
monitor for speeds up to 10Mb
- Monitors all thirteen
RS-530 signal lines - ten differential and three single ended
- Six in-line LED monitors
show the signals from the DTE - TD, RTS, DTR, TSET [V11/RS-422] and LL, RL
[V10/RS-423]
- Seven in-line LED
monitors show the signals from the DCE - RD, CTS, DSR, DCD/RLSD, TSET,
RSET [V11/RS-422] and TM [V10/RS-423]
- Four state monitoring of
signals - MARK / SPACE / CLOCKING / NONE
- Interface or battery
powered

Abbreviated
Specification & additional information |
- Four state LED monitoring:-
- (a) Differential (balanced)
lines:- 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:- red =
SPACE/ON (> 0.3V above sig. gnd.), green = MARK/OFF (> 0.3V below sig. gnd.),
both = data or clock, neither = no signal (< +0.3V relative to signal ground)
- Speeds: Differential
(balanced) up to 10Mb/s, un-balanced up to 500Kb/s
- Interface connectors: One
gold plated female DB25 type connector, one gold plated male DB 25 connector
- All 25 lines wired through
the unit
- Power: interface power is
sufficient for most situations (the power LED indicates the strength of the of
the power available), battery powering is possible for extremely weak interfaces.
Two AA
size batteries (provided) last for over 50 hours
- Housed in a rigid ABS case
- Temperature: operating = 0 to
+ 50 deg.C (32 to 122 deg.F)
- RoHS compliant, CE marked,
made in EU
