SIN-10 Intelligent Serial Adapter

The SIN-10 is an intelligent serial line converter that simplifies application software development and improves overall performance. Dual, independent UARTS (COM ports) permit spooling commands at rates between 1200 and 115k baud. Specific operating instructions are contained in the SIN-10 Users Guide.

The SIN-10 has a built-in microprocessor that offers a number of features:

∙Emulating the SIN-8

∙Diagnostic LED’s

∙Numerous Input baud rates

∙Output (party line) baud rates – including the special 470k baud rate

∙DB-9 serial input connector

∙RJ-45 party line connector

∙5 volt powered from controller

∙250 character buffers for multiple commands per line

Because the SIN-10 eliminates the need for special echoed character software it can be used in Windows applications where either the machine or software is slow and/or the operating system prevents direct programming of input or output instructions.

SIN-10, intelligent serial line converter

There are several commands that the SIN-10 can execute including: “Scan for axis present” (required initialization) and “Wait until motion complete” (1 or all axis). A typical command string to a X-Y- Z system could be:

X+1000;Y+1000;Z+1000;9W*;XZ;YZ;ZZ

This would cause all three axes to move the specified number of steps; wait until motion is stopped then read back the three positions.

Other Party Line Signals

In addition to the serial data bus wires several other signals exist in the AMS party line interconnect.

1.GND (pin 2) Ground is common for all devices (axis). All power supply commons are connected to prevent high common mode voltages. Please note that the power common is generally connected to the case return.

2.+5 Volts (pin 7) is available to power the serial adapter (SIN-8 or SIN-10) from the first axis.

3.MVG Not available in this product. Software pooling must be used to query motion.

Note, The SIN-10 determines motion via special SIN-10 instructions.
