DATATEK D−2000/2166 CONNECTIONS
The VM 3000 can be connected to a Datatek D−2166 Buffer Control Module, which in turn is connected to a D−2000 Series
routing switcher (see page 2−27). The protocol setting is: 38400 baud, 8 data bits, even parity, 1 stop bit.
Although the VM 3000 is connected to one of the D−2166 Buffer Control Module ports labelled “RS−232,” the port must
be set with an internal jumper to operate according to RS−422. Refer to the manual supplied with the D−2166 for more infor-
mation.
