Maple Systems OIT Family (ASCII) - Manual (Page 57)

Function Key LED Coils (if applicable)
Default: C896
Range: C0 to C1023
The function key LED coils register is the 16-bit register that the OIT reads for information
about illuminating the function key LEDs (not available on all OIT models) if the function
key LED is controlled by the ASCII host. The default is C896-911, but you can choose any
16 bit register in the Coil (C) Register range of 0 to 1023.
Note: The least significant bit corresponds to the LED on F1 (example: C896 = F1 LED, C897
= F2 LED, etc. if C896 is selected).
Status LED Coils (if applicable)
Default: C912
Range: C0 to C1023
The status LED coils register is the 8-bit register that the OIT will read for information about
illuminating the status LEDs (not available on all OIT models). The default is C912-919, but
you can choose any 8 bit register in the Coil (C) Register range of 0 to 1023.
Note: The least significant bit corresponds to the LED on S1 (example: C912 = S1 LED, C913
= S2 LED, etc. if C912 is selected).
Address
Default: 1
Range: 1 to 100
The address field is the OIT address used by the OIT when the OIT is communicating to an
ASCII host using Network mode. The ASCII host must “log on” to the OIT by first sending
the OIT address before the control command.
Note: The ASCII host must send the OIT address in hex format (for OIT #100 the host sends
64 since 64 hex = 100).
Baud Rate
Default: 9600 baud
Also available: 300, 600, 1200, 2400, 4800, 9600, 19200 baud
This is the baud rate that the OIT uses to communicate with the ASCII host. Lower baud
rates will dramatically slow down the OIT’s ability to monitor the ASCII host so the fastest
baud rate should always be used. The default baud rate is 9600.
Parity
Default: None
Also available: Even, Odd, None, Mark, Space
This is the parity that the OIT uses to communicate with the ASCII host. The default parity is
none.
Data Bits
Default: 8 bits
Also available: 7 or 8 bits
This is the character length (specified in bits) that the OIT uses to communicate to the ASCII
host.
Stop Bits
Default: 1 bit
Also available: 1 or 2 bits
This is the stop bits per character that the OIT uses to communicate with the ASCII host.
