INCORPORATED
MCS-11 CONNECTORS
There are two MCS-11 DB-15 female connectors (Two MCS-11 ports). Each port is DTE (accepts clock)
and can be configured for RS-422 or RS-232. The second port can also be configured for DCE (outputs
clock) and set to a user specified baud rate.
RS-422 SIGNALS:
•
Idle condition:
+
data line (the A-lead) is more negative than the
-
data line (the B-lead) during the
inter-packet interval.
•
Clock phase: Data changes on positive going edge of the
+
clock. Data is stable on the negative
going edge of the
+
clock.
•
For DTE, the following are outputs from 2310 AL: Return Clock, Transmit Data and Off Hook.
DTE inputs are Receive Clock, Receive Data, and Transmit Clock.
•
For DCE, the following are outputs from the 2310 AL: Receive Clock, Receive Data and Transmit
Clock. DCE inputs are Return Clock, Transmit Data and Off Hook. Only port 2 can be set to RS-
422 DCE.
MCS-11 ports input termination:
121 Ohms differential:

data input biased to gnd. with 1K)
FRONT PANEL INDICATORS
one green power indicator
one red unit-fail indicator
one red RSS alarm indicator
MCS-11 port 1 (green LEDs): TX clock, TX data, RX clock, RX data
MCS-11 port 2 (green LEDs): TX clock, TX data, RX clock, RX data
thirty-two green alarm point indicators (16 of which are also used for control relay status indication)
ENVIRONMENTAL
operating temp: 0 to 70 degrees C.
humidity range: 5% to 95% R.H. non condensing
MOUNTING
The MCS-11 Encoder mounts in a standard 19 inch rack. Mounting ears provide for a 5 1/8 inch
projection out from the mounting surface. The mounting ears may be relocated to threaded holes near
the front for flush mounting or 2 inch projection mounting.
