Installing the Modem in the Universal Data Shelf
In switched-carrier mode (SW2-8 set to OFF), the RTS/CTS delay is 23 ms.
SW 2-9 − RX Termination (high- & low-speed modes)
SW2-9 ON = Disable Rx Termination
OFF = Enable Rx termination
SW2-9 selects whether RX termination is enabled for a modem. If you set this switch OFF, the receiver is terminated with 600 Ω. If you set this switch ON, the receiver is not terminated.
SW 2-10 − Ground Option (high- & low-speed modes)
SW2-10 ON = Modem signal ground is connected to chassis ground OFF = Modem signal ground and chassis ground disconnected
SW2-10 determines the grounding option for the modem. Setting this switch ON connects the modem signal ground to chassis ground. Setting this switch OFF disconnects the modem signal ground from chassis ground.
Installing the Modem in the Universal Data Shelf
After you set the modem’s configuration switches, you can install it in a slot within a 19- or 23-inch Telenetics or Motorola RM16M Universal Data Shelf. The modem is installed or replaced from the front of the Universal Data Shelf, without disturbing the cable connections on the back of the Shelf. The modem can be installed and removed without having to remove power from the Shelf. Special tools or test equipment are not required for installing the modem.
1.Wear an antistatic wrist strap over your wrist on your bare skin (not over a shirt or jacket).
2.Remove the wrapping protecting the modem.
