Before a PC can begin to receive real-time data from the iSIC, a RS-232 Direct Connect Cable must be connected into the iSIC enclosure.
Important: Always remove power from all NexSens communications devices when wiring to the iSIC.
NexSens supplies a variety of permanent RS-232 Direct Connect Cable lengths ranging from 25 ft to 250 ft. For stand alone applications without continuous real time connections, the supplied A72 RS-232 Direct Connect cable may be used to communicate with the iSIC. This cable simply requires connecting the iSIC DB9 connector to the PC COM port.
For real time connection to the data logger, A60-A64 Cables will need to be used. If an MS3 connector is located on the outside of the iSIC enclosure, simply connect the MS3 connector on
the A60-A64 DB9 to MS3 cable to the MS3 connector located on the iSIC and the DB9 connector to an open COM port on a PC running iChart software.
MS3 to DB9
If an MS3 connector is not available, an A60-A64 DB9 to flying lead cable can be used.
Wiring a direct-connect cable using a flying lead dongle, BTX: CD-MX9M
A direct RS-232 or RS-485 connection to the iSIC can be run through the DB9 port with a BTX CD-Mx9M dongle.
For RS-232 connection using the iSIC direct connect cable, the following pins are used:
|White||Terminal 2||Pin 2||Tx (iSIC to PC)|
|Blue||Terminal 3||Pin 3||Rx (PC to iSIC)|
|Green||Terminal 5||Pin 5||GND|
For RS-485 connection using a supplied cable, the following pins are used:
|Terminal 5||Pin 5||GND|
|Terminal 6||Pin 6||RS485A|
|Terminal 8||Pin 8||RS485B|
Secure the dongle to the iSIC DB9 port. Be sure to tighten the screws with a screwdriver.
