Available Port Types
Channel (COM Port) Available Port Types
COM1 RS232, RS232H, RADIO, TW-RADIO
COM2
COM3
RS232*, RS232H, RS485*
TTL INTERFACE*
COMPASS INTERFACE*
TTL Only (listed as RS232)
*The TTL INTERFACE and COMPASS INTERFACE are multiplexed connections of COM2, along
with the RS232 and RS485 connections.
COM2 is multiplexed to support up to four fully separated communication
links.
The following table summarizes the typical communication link associated with each sensor type:
Sensor Type
Code
(Line Item #1)
Name
Typical Port Type
(Line Item #18)
Typical Baud Rate
(Line Item #19)
11 Serial Compass
RS232 or TTL (TTL if
used on COMPASS
INTERFACE port)
4800
12 CCSAIL Sensor
19 Asynchronous CCSAIL Sensor
RS232, RS485 or
Two-way Radio
9600 or 1200 (if on
two-way radio)
15 GPS Receiver RS232 or RS485 4800
16
General Serial Script Sensor
(USI)
Any
Any
13 SDI-12 Sensor
17 Continuous SDI-12 Sensor
18 Concurrent SDI-12 Sensor
RS485 1200
COM1 and COM3 are NOT multiplexed: if you attempt to connect more
than one serial sensor (or other communications link) to COM1 or COM3
using different port types, you will get garbled and unusable
communication.
In addition to the Port Type & Baud Rate for a General Serial Script Sensor (USI), you also need to
specify four more serial port parameters:
Line Item #20: Sensor Bits Per Character Valid values are 5, 6, 7 or 8.
Line Item #21: Sensor Parity Valid values are N (none), E (even) or O (odd).
Line Item #22: Sensor Start Bits Valid values are 1 or 2.
Line Item #23: Sensor Stop Bits Valid values are 1 or 2.
The available serial sensor types are summarized in the following table, along with their available
channels.
