The ERM-Mux/plus Asynchronous RS485/422 Serial Tributary Card provides six independent RS-485/ RS-422 data channel capability.
Incorporating six separate channels, each channel can independently assign any Nx64 timeslots from the aggregate E1. Each channel
uses a pluggable 4-pin terminal block for connection one or two twisted pair wires. No cables are provided with this card. When
connecting to RS-485, the channel supports 4-wire Full Duplex or 2-wire Half Duplex RS-485 transmissions for serial control or data
acquisition.

The ERM-Mux/plus Sync/Async RS232 Serial Tributary Card provides six independent RS-232 data channel capability. Incorporating six
separate channels, each channel can independently assign any Nx64 timeslots from the aggregate E1. The single DB62 connector
mates to a 1 to 6 cable that terminates to DB25 female connectors. These serial data channels may be linked to leased line modems for
further extension or connected to other data terminal or data acquisition devices. When configured for synchronous use, the data
connectors carry both clock and data. For asynchronous use, the clock signals can be ignored.
