ASM-40 Ver. 1.0 Installing the ASM-40/R Card 5-7
Connecting the Interfaces
ASM-40/R uses the ASM-MN-214 rear panel terminal block ports for the line
connections. The 25-pin D-type female connector serves as a DTE port.
1. Remove the protection cover from the terminal block connectors.
2. Connect the terminal block to the ASM-MN-214 terminal block connector.
3. Connect the line to the terminal block as follows: connect transmit pair to the
terminals marked XMT, the receive pair to the terminals marked RCV, and the
fifth screw to ground (optional).
4. When operating ASM-40/R with unbalanced interface, use CIA/TB-BNC/214
adapter, which converts the terminal block connector into two coaxial BNC
connectors.
5. If required, attach the appropriate CIA (CIA/X.21/1, CIA/V.35/1, CIA/ETH) or
V.36 adapter cable to the DB-25 connector on the card cage rear panel.
6. Connect the DTE cable to the DB-25 connector, other side of CIA or adapter
cable (depending on your version of the card interface).
7. Connect power to the ASM-MN-214 card cage:
To connect AC power, connect the power cable to the mains supply.
To connect DC power, refer to
DC Power Supply Connection Supplement
of the ASM-MN-214 Installation and Operation Manual.
The ASM-MN-214 card cage has no power switch. Operation starts when the
power is applied to the rear panel POWER connector. When applying power, first
connect the plug of the power cord to the ASM-MN-214 POWER connector and
then to the mains power source (outlet).
