− RX Termination (high- & low-speed modes)
SW2-9 ON = Disable 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.
