POL SELECT
Path: / POL SELECT
Type:
Data Editor
Syntax: POL-SELECT [= n] | [D]
Range: Integer: 1 .. 2
1 Pol 1
2 Pol 2
Notes: POL SELECT selects which POL input will be used for tracking. This setting is used
to control an RF switch internal to the DTR, and may also be used to control an
external switch using I/O Interface #1 on the back panel. GPIO 6 and 7 become
active based on the POL SELECT setting. Pins 11,24 represent the POL1 state and
pins 11,25 represent the POL2 state. These pin groups are connected to dry relay
contacts (1Amp max current).
POL SELECT (FOUR PORTS OPTION ONLY) (v1.19.08 or later)
Path: / POL-SELECT
Type:
Data Editor
Syntax: POL-SELECT [= n] | [D]
Range: Integer: 1 .. 4
1 Pol 1
2 Pol 2
3 Pol 3
4 Pol 4
Notes: POL-SELECT selects which POL input will be used for tracking. This setting is used
to control an RF switch internal to the DTR, and may also be used to control an
external switch using I/O Interface #1 on the back panel. GPIO 4, 5, 6 and 7
become active based on the POL SELECT setting. Pins 11,24 represent the POL1
state , pins 12,25 represent the POL2 state, pins 9,22 represent the POL3 state,
and pins 10,12 represent the POL4 state. These pin groups are connected to dry
relay contacts (1Amp max current).
PORT 1
Path: / CONFIGS COMM-PARAM PORT-1
Type: Sub Menu
Syntax: PORT-1
Notes: PORT 1 is an RS-232 (only) port used for remote M&C communications. The data
parameters are set in factory to: 8 data bits, 1 stop bit, no parity. Port 1 is
available on the back panel as a 9-pin D subminiature socket connector with the
following electrical pinout: pin 2=RX (from DCE); pin 3=TX (from DTE); pin
5=Signal Ground. The other pins are not connected.
