Data Port RS-530
2.5.1
Receive and transmit data connections are accomplished through the 25-pin D-sub (F) connector
labeled TX/RX DATA, RS-530 on the rear panel.
In addition to connector pin-outs, Figure 46 provides cable pin-outs that convert the RS-530 interface
to an RS-530/449 interface.
Data Port HSSI
2.5.2
Receive and transmit data connections are accomplished through the 50-pin SCSI-2 (F) connector
labeled HSSI DATA (P3) (J18 on AMT-73L) on the rear panel. Refer to Figure 49 for pin-outs.
Data Port Ethernet
2.5.3
Receive and transmit data connections are accomplished through the 8-pin RJ-45 (F) connector
labeled 10/100BT DATA (JA on AMT-73L) on the rear panel. Refer to Figure 50 for pin-outs.
Monitor and Control RS-232
2.5.4
The terminal is connected to the 9-pin D-sub (F) connector labeled M&C/RS-232 (P8) (refer to Figure
51) on the rear panel, via a straight-through cable.
Monitor and Control RS-485
2.5.5
The rear panel 9-pin D-sub (F) connector labeled M&C RS-485 (P7) (refer to Figure 53) is provided for
RS-485 compatible M&C of the modem and BUCs that are also equipped.
Monitor and Control 10/100BaseT Ethernet
2.5.6
There are two 10/100BaseT Ethernet M&C ports on the rear panel. One is labeled P6, and the other is
labeled P1 (both are RJ-45 connectors, see Figure 50 for pin-outs). The P1 connector is used during
manufacturing, and relates to the demodulator only, and should not be used in the field. P6 provides
Ethernet capabilities for all functions of the modem, including the modulator, demodulator, and
interface cards.
Monitor and Control Alarms
2.5.7
The connector labeled P5, a 15-pin D-sub (F) provides Form C relay outputs of the modem's status.
Refer to Figure 56 for pinouts and status description.
Redundancy
2.5.8
This is an optional feature, although the connector appears on the rear panel (P4, a 15-pin D-sub
female). If the modem is so equipped, refer to Chapter 11 for details. A redundancy kit can be
purchased from AdvantechAMT to allow two modems to be connected in a 1:1 redundancy
configuration.
2.6 Data Connections (AMT-73L Series)
The AMT-73L has a different chassis design compared to the AMT-70. Specifically the RS-530 rear
panel connector is replaced by an EIA/TIA-449 port although the RS-530 is still available as an option if
required, and an External Clock Input has been added. The remaining connectors are the same as for
the AMT-70, above, but with different nomenclatures (see Figure 45).
Data Port EIA/TIA-449/MIL-STD-188-114
2.6.1
Receive and transmit data connections are accomplished through the 37-pin D-sub (f) on the rear
panel (refer to Figure 54 for pin-outs).
