Front Panel Description
STATUS: Green LED illuminates when the unit is powered. Red LED illuminates when an alarm
exceeding thresholds is detected or other unit failure.
ACO: Amber LED illuminates when the Alarm Cutoff switch is On (switch left) indicating that the
alarm relay contacts are forced to the No Alarms condition.
ACO SW: Alarm Cutoff switch controls the alarm relay circuitry. When the switch is On (left), the
circuitry is deactivated. The ACO indicator still functions normally.
ADDRESS: This 8-position switch (Switch 1) sets the address of the unit ta rg eted by the comm and from
the EM8000 cont r oll er. Val i d a dd re s se s a r e 0 thr o ug h 253 with zero being the br o ad c as t a dd r e s s a n d 25 3
reserved as a universal hailing frequency.
FORCE: Amber LED illuminates when the select switch is in either the A or B position. NMS
commands will not override this switch.
A / B: Green LEDs illuminate indicating which input (A or B) is being broadcast to the ports. If both
ports (A and B) have input, only the selected port’s indicator illuminates.
Select: The select switch forces the input to either the A (switch left) or B (switch right) inp ut. N (switch
center) is for normal operation.
NMS BR: S2-1 and S2-2 set the NMS bit rate. Refer to the NMS Bit Rate table below for setting
information.
SUPV BR: S2-3 and S2-4 set the Supervisory port bit rate. Refer to the SUPV Bit Rate table below for
setting information.
LSB: S2-5 sets the Least Significant Bit with respect to the duplex select. Refer to the Duplex Select
table for setting information.
Duplex Select : S2-6 and S2-7 select the channel (1-12) that is full duplexed to the selected (A or B) input
channel. No channel is selected when set to zero. The expansion settings (A EXPD, B EXPD, and A/B
EXPD) full duplex back to their respecti ve T1 in put lines. For e xample, th e A EXPD setting full duplex es
the return feed back to the T1 A input line; the B EXPD setting full duplexes the return feed back to the
T1 B input line; and the A/B EXPD setting full duplexes the return feed back to the respective T1 A and
T1 B input lines.
MSB: S2-8 sets the Most Significant Bit with respect to the duplex select. Refer to the Duplex Select
table for setting information.
Activity Indicators: The two red activity indicators allow you to identify transmission flow in the unit.
The left light indicates supervisory port transmission. The right light indicates NMS bus transmission.
SUPV: The supervisory por t allow you to configure the unit’s software through a VT100 connection.

Rear Panel Description
NMS (IN/OUT): These two ports connect th e chassis to the Tx PORT EM8000. W ith in the cha ssis, each unit
is physically connected to the next unit in a daisy chain. Each unit in the NMS chain must have a unique
address, however, they all use the same NMS bit rate.
Expand (A/B): These two 8-pin modular jacks expand the A or B inputs to other 1061 units providing
additional outputs. The maximum number of units is ten.
T1 IN (A/B): These two 8-pin modular jacks are used for the T1 input signal as wel l as the output of each
input. They output AIS with no input.
T erminate/Unterminate: These two slide switches set the A or B input. Terminate is used when the
expansion connector is not used. Unterminate is used when the expansion connector is daisy chained. The
recessed switches can be moved with a screwdriver. The last unit in a daisy chain must be terminated.
T1 Broadcast Port: This 50-pin female connector is used for the expanded outputs of either the A or B
inputs. Refer to the T1 Multicast Port Pinout table.
Alarm/P ower: This 10-pin connector is used as a power and alarm conne ction. The unit requires a -48
VDC power source capable of supplying 100 mA current. The chassis ground lead is connected to pin 8. The
-48 VDC lead is connected to pin 7. The return lead is connected to pin 5. The alarm connection is made on
pins 6 and 9 to operate in a normally closed mode (NC - opens on alarm) or on pins 6 and 10 to operate in a
normally open mode (NO - closes on alarm). The contacts are rated at 1.0 Amp AC or 1.0 Amp DC. 18 to 20
gauge wire is recommended. The external alarm connectors are unpowered, isolated inputs indi cating
external alarms on inputs A and B. External alarm A is connected on pin 1 (+) and pin 2 (-). External alarm B
is connected on pin 3 (+) and pin 4 (-). They are 10 mA current loops and must be powered externally.
