6.5.1 Control output
 The 16 points of control output is divided into H and L groups with 8 points each.。
 16 points of output are all OPEN DRAIN output types, with 50mA short-circuit current limiting
protection function.
 OPEN DRAIN Output，max. loading is VDC24V/30mA，only for driving SSR.
 The wiring diagram of DTM-DOX & SSR is as below.
Note: In the same DTM group, when the IO expansion module only uses DTM-DOX models, the number of
DOX allowed is up to 15. The maximum number of other combinations is 8.
6.5.2 Control Input
 H/L input pin OPEN, DOX #1~8 LED light default displays O1~O8 status, H/L LED light is on.
When the H/L pin is short-circuited to COM, the status of O9~O16 is displayed, and the H/L LED
is off.
6.5.3 Indicator LED
 10 LED，PWR、H/L、O1~O8。
 PWR(GREEN) ，indicating that power is normal
 H/L(RED)，When the light is on, the light of O1~O8 indicate the ON/OFF status of CH1~CH8.
When the light is off, the lights of O9~O16 indicate the ON/OFF status of CH9~CH16.
 O1~O8(GREEN)，They are the indicator light for output 1~16 output action, used with H/L light
6.5.4 Software setting
DTM-DOX output light switching:
Communication address: x7C1H ，x is the internal station number of DOX .
Written content 00A0H : the light of DOX OUT1~OUT8 (H/L LED on)
00A1H : the light of DOX OUT9~OUT16(H/L LED off)
If the content read is 00A0H or 00A1H, it means DOX model, and the rest are DOR, DOV...
