Counter Indicator

The TEX-CTR10 indicator is the ideal so-

lution for a variety of counting and rate

application requirements.

This meter has been designed for ease

of use, with intuitive, scrolling text

prompts that guide you step-by-step

through the setup process.

The front panel includes a 6 digit LED

display and five front panel buttons, for

simple operator interface.

One of the five buttons is user-pro-

grammable, so you can customise it as

a shortcut to your most frequently used

feature.

5.2 - How to remove the input module

A If the meter is already installed, remove it from the panel, and unplug all plugs

from the back of the unit.

B Using a small screwdriver or similar implement,

press downward into one of the slots at the

rear of the case. This will disengage one of

the tabs which holds the back plate on, al-

lowing it to be gently levered away at

one corner.

C Holding the loosened corner open

with one hand, disengage the le-

ver on the opposite slot (Fig 1).

D You should now be able to remove the back plate. If it does not unclip easily,

you may need to disengage the two remaining tabs by repeating steps 5.2B–C

on the other side of the meter.

Fig 1

E Slide the analog input module out

of the meter case (Fig 2). (See 3.1A

to identify the input module.)

F Position the headers on the input

module as required for your sensor

type, referring to 5.1.

G Slide the input module back into

the meter case.

Make sure that it is sitting in the tracks on the le and right. Press rmly until the input module is fully inserted and sits ush with the other boards that are visible from the back of the meter.

H Replace the back plate.

Begin by inserting the two lower tabs into the slots, and then position the upper tabs so that they will not catch on the top lip of the meter case. Apply rm pressure until the back plate clicks into place.

APPENDIX A - SERIAL MODES

A.1 - Custom ASCII mode

Custom ASCII is a simple, custom protocol that allows connection to various PC con-

guration tools. ('Custom ASCII' diers from the 'Modbus (ASCII)' protocol used by

some devices.) Custom ASCII command strings must be constructed in this order:

Start - Use 'S' for the start character of a command string (not case sensitive). This

must be the rst character in the string.

Controller Address - Use an ASCII number from '1' to '255' for the controller address.

If the character following the start character is not an ASCII number, then address '0' is assumed. All controllers respond to address '0'.

Read/Write Command - Use ASCII 'R' for read, 'U' for unformatted read, or 'W' for

write (not case sensitive). Any other character aborts the operation.

In Custom ASCII mode, data is normally read as formatted data (which includes decimals and any text characters that may be selected to show units). However it is also possible to read unformatted data by using a 'U' in the read command. There is no unformatted write command, as when writing to xed point registers, any decimal point and text characters are ignored.

number from '1' to '65535'. This character must be specied for a write com-

mand, but may be omitted for a read command, (in which case the controller

will respond with the data value currently on the display).

Separator Character - The separator character can be either a space or a comma,

and is used to separate the register address from the data value.

Data Value - Must be an ASCII number. The absolute limits for this number are

-1000000 to 1000000, but please note that not all registers will accept this range.

Message Terminator - This is the last character, and must be either a '$' (dollar) or

an '*' (asterisk). Neither of these characters should be used elsewhere in the

Page 20

message string. If '$' is used, a 50ms minimum delay is inserted before a reply is sent. If '*' is used, a 2ms minimum delay is inserted before a reply is sent.

Custom ASCII Read/Write Examples

Example Description

SR$ Read display value from all controllers, 50ms delay.

S15R$ Read display value from controller address 15, 50ms delay.

S3U40* Read unformatted data in channel 4 from controller address 3, 2ms delay.

S2W2 -10000$ Write -10000 to the display register of controller address 2, 50ms delay.

SWT CHAN_1$ Write ASCII text string Chan_1 to channel 1 text register, 50ms delay.

Custom ASCII Registers

2 Process display

4 Flow rate

5 Total

34 D/A scale low value

36 D/A scale high value

Controller Response - Aer the controller has completed a read or write instruction,

it responds by sending a carriage return/line feed (CR/LF) back to the host. If

the instruction was a read command, the CR/LF follows the last character in the

ASCII string. If it was a write command, CR/LF is the only response sent back.

The host must wait for this before sending further commands to the controller.

If the controller encounters an error, it will respond with a null (0x00) CR/LF.

A.2 - Modbus (RTU) mode

Modbus (RTU) is an industry standard RTU slave mode that allows connection to a

wide range of devices. Modbus registers are all holding registers, and should be ac-
