Tips
For details, see "6.2.1 List of Error Codes" (page 56).
y Parameters relating to RS-232C (No. 25 to 28) can be modied only on the rst counter.If you
modify a parameter, reset the power switch of all the connected counters.
5.4.2 Assignment of CHs
When the power is turned on, the states of the counters are determined, and the CHs (channels) used
by RS-232C commands are automatically assigned.
The CHs are assigned starting from 01, from the CELs of the rst counter.
For counters with the display mode set to the optional one- or two-axis display, CHs are assigned to
only the used CELs and not to unused CELs.

5.4.3 RS-232C Data Output Duration
The maximum output duration of the command to output all data (GA00CRLF) can be calculated with
the formulas below.
1) When the transmission rate is 9600 bps
Maximum output duration [ms] = Number of connected counters × 5 + Number of connection
channels × 17 + 6
Calculation example
One EH-102 + 1 channel connection = 1 x 5 + 1 x 17 + 6 = Max. 28 ms
Ten EH-102 + 20 channels connection = 10 x 5 + 20 x 17 + 6 = Max. 396 ms
2) When the transmission rate is 19200 bps
Maximum output duration [ms] = Number of connected counters × 5 + Number of connection
channels × 8.5 + 3
Calculation example
One EH-102 + 1 channel connection = 1 x 5 + 1 x 8.5 + 3 = Max. 16.5 ms
Ten EH-102 + 20 channels connection = 10 x 5 + 20 x 8.5 + 3 = Max. 223 ms
Tips
Processing time of the PC is not included.
