Utah Scientific Party Line Connection Using UDI-1B
The CM- 4400 can be connected to a Utah Scientific Party Line through a
UDI-1B Universal Data Interface (see Figure 227). Some UDI-1B units are
equipped with a 9-pin RS-422 port; others ar
e equipped with a 25-pin RS-
232 port. Either type can be used.
The protocol for the UDI-1B port must be set
at: 9600 baud, 7 data bits, even
parity, and 2 stop bits. The UDI-1B must be equipped with software version
81.4 or later. The UDI-1B “AUX” rotary switch needs to be set to “E” for
“PL-160 Mode” and to enable all mode commands. Refer to the UDI-1B
manual for detailed procedures.
Note If the RS-232 port is used, it is advisable to use an RS-422 to RS-232 con-
verter. A Black Box, model GJ-IC455B Interface/converter, is available from
Grass Valley.
