Ramsey Electronics URC1 manual To set a Level, To set a Control Pot

To turn an output off:

*0{output set #}{Output #}0 or *6{output set #}{Output #}0 This code replies with a short then long tone to indicate “A” for acknowledge.

Note that the last one or zero denotes on and off respectfully. Note there is only eight output sets (0-7) and eight outputs per set (0-7). Any number entered over seven causes an error and the command is aborted. Also note that output 0,0 is used as a confirm tone output. In other words don’t use it as an output unless it is to generate a tone.

To set a Level:

To set directly: *L{Level #}[0-255] or *5{Level #}[0-255]

Using this method you can quickly set any level you desire. For example if you want 2.5 volts out, enter 127 for the level, and if you want the full 5 volts enter 255. Three numbers must be entered for the level.

This code replies with a short then long tone to indicate “A” for acknowledge.

1/4 scale example on level output 0: *50064

Where 5 is the command code, 0 is the device code, and 064 is the value.

To vary the level down: *L{Level #}* or *5{Level #}*

Press and hold the last asterisk to keep decreasing the level. The level stops decreasing at a value of zero. When it has reached zero, the URC1 replies with a short then long tone to indicate “A” for acknowledge.

To vary the level up:*L{Level #}# or *5{Level #}#

Press and hold the pound sign to keep increasing the level. The level stops at a value of 255. When it has reached 255, the URC1 replies with a short then long tone to indicate “A” for acknowledge.

Note that there is only four level outputs (0-3), so any value over 3 will cause an error and the command will be aborted. Also any value over 255 in the level code will do the same.

To set a Control Pot:

This method is almost identical to setting the levels except for the command code.

To set directly: *C{Level #}[0-255] or *2{Level #}[0-255]

Using this method you can quickly set any resistance you desire. For example if you want 5K ohms at the wiper, enter 127 for the resistance, and if you want the full 10K ohms, enter 255. Three numbers must be entered for the level.

The URC1 replies with a short then long tone to indicate “A” for acknowledge.
