PCS-9785 Satellite Synchronized-Clock
6-11
Date: 2019-07-05
Command format: F?
To query the current value of optical inputs reception mode.
NOTICE!
For a IRIG-B signal input channel, the optical or electrical input working mode is
optional. To use the optical mode, the relevant electrical input must be unconnected
and its input mode should be TTL
6.3.5 Electrical Inputs Reception Mode
The two electrical inputs on the CLK module are used to receive IRIG-B signal from other clock
synchronization source. The reception mode of each input is optional between TTL (default) and
RS-485.
Command format: EDD
E
The command key word
First D
Reception mode of the first electrical input, 1: TTL; 0: RS-485
Second D
Reception mode of the second electrical input, 1: TTL; 0: RS-485
Example: "E01" means the first is RS-485, the second TTL.
Command format: E?
To query the current value of electrical inputs reception mode.
NOTICE!
For a IRIG-B signal input channel, the optical or electrical input working mode is
optional. To use the electrical mode, the relevant optical input must be unconnected
and its input mode should be idle-light-on.
6.3.6 Input Cable Length
To reduce the time delay due to signal transmission from clock source to this device, it is
necessary to consider the transmission cable length. This device can compensate the delay based
on the length so as to minimize the error in time synchronization.
Command format: ADDDD or BDDDD
A or B
The command key word, A signifies the first input while B signifies the
second
DDDD
Length of input cable (default value = 0), Unit: meter; Range: 1~9999;
Step: 1
Example: A0030 means the first input cable length is 30m
Command format: A? or B?
To query the current value of input cable length.
